00:00The Cannondale Synapse and the Trek Domane have long been the pinnacles of the road bike endurance
00:05category. The question that we've been left with is how do these two new kids on the block really
00:10stack up against each other and which one should you really choose? So we're going to compare both
00:16bikes against ride quality, aesthetics, their features and of course the whole range option
00:22and the value in which they provide. So first off let's start with the features of the bike
00:26and you've got a pretty headline worthy feature. Tell us what it is. Yeah so I mean there are two
00:33main things to unpack for the Synapse and one is the bike itself and the other is the smart sense
00:39and that's really the the headline feature of the Synapse I would say this time. Let me just
00:43read how Cannondale describe it. It's integrated lights and radar designed to provide enhanced
00:48awareness while also creating heightened visibility so the rider can more effectively
00:52see and be seen. I mean the theory and the idea is a pretty rock solid one but in terms of execution
00:59and you know we're looking at this now from over a year on from when the bike was released
01:04how do you think it's played out for them? I think the problem with smart sense is that you can't
01:08choose your lights you're stuck with the ones that are there which are made by Lezyne. They're
01:11decent lights you know I thought they were good but yeah you know you just don't have the choice
01:15you're stuck with those lights and there's the battery on the down tube as well I mean you could
01:20take it off but it's going to leave the sort of cradle so you can't opt out of the smart sense
01:24system unless you go with the bottom of the range which is the four which doesn't have smart sense
01:29but is smart sense compatible so you could retrofit it if you wanted to. Does the Synapse have any
01:34other really key features worth mentioning? I mean there's the endurance geometry which mostly
01:38consists of a taller front end the size 56 which I rode has a almost a 60 centimeter stack height
01:45if you want comfort then it's all about that high front end. So tell me about the Domane so
01:50ISO speed decoupler? Yeah so that you've absolutely nailed it that is kind of the big feature of the
01:55Domane is that ISO speed functionality however there's a big difference between the Gen 3 and
02:01the Gen 4 version of the bike so previously you had two ISO speed points one in the head tube
02:06and one at the seat cluster and the one at the seat cluster was adjustable however it is no longer
02:13adjustable they've also stripped out obviously the one at the head tube so you're left with one
02:17ISO speed decoupler and it is non-adjustable now the reason why they got rid of that adjustability
02:22is because they found that riders weren't actually ever adjusting it now this has had kind of two
02:28really key benefits one is simplicity and looks it's just a lot cleaner and a lot smoother but
02:35also by making it non-adjustable and dinching the front end ISO speed so much lighter I think they
02:41managed to drop around about 800 grams out of the frame alone just by getting rid of and changing up
02:48their ISO speed system so that's the key headline feature for this bike the second one which is
02:54slightly less exciting and it is something that came across from the Gen 3 it's nothing new
03:00but I still really like it is actually the internal frame storage you've got a little access
03:05port down on the down tube where you can open up a door and then pull out the Bontrager tool roll
03:10that you can fill with all your spares and then pop it back in the frame which just means that
03:14you might not need to use a saddle bag or have a load of tools you know pulling down
03:18on your jersey pockets which is always nice so yeah those are the kind of the two key features
03:22from the Domane so Simon tell me about the Cannondale Synapse's ride quality so I think
03:32that um probably when I rode the original Synapse and we're talking about 16 years ago now
03:37it felt really really comfortable but that's probably because the race bikes at the time were
03:41so harsh the tires were very narrow the clearance was very tight so it felt really comfortable but
03:45now I think that the new Synapse is not really all that different from race bikes and mostly this is
03:51because of the tires race bikes now come with really wide tires and so does the Synapse the
03:57difference really is not that great between the Synapse and a race bike I think with with the
04:01Synapse where the difference really is is in the position the rider position you've got a very tall
04:06front end um the 56 that I rode the stack height was nearly 60 centimeters so it puts you in a very
04:11tall position where you're kind of you know you're looking over the roofs of cars which is great if
04:15you're using it to commute on if you if you're struggling a bit with a bad back it means you
04:19can sit more upright and you're more comfortable so all the all of the comfort really is in the
04:22position rather than the the bike itself although having said that Cannondale's built in these flex
04:27zones into the rear triangle adds a bit more compliance but I didn't really feel those um I
04:32think the comfort was all in the tire pressures for me and the rider position okay so then how
04:37did that translate towards how the bike was like to ride in terms of a if you wanted to you know
04:42show it a bit of aggression what did it feel like in those moments yeah I mean I think it's probably
04:47it's more performance orientated I would say and uh and like I was saying there's not really all
04:52that much difference between the kind of ride feel of the Synapse and I've been riding the Cervelo S5
04:56at the moment and you know it sounds crazy because the S5 is a pure race bike but really there's not
05:01that much difference in the ride quality it is a fast bike it's responsive you know it has the same
05:06sort of angles um classic sort of geometry as a race bike um so if you want to ride it fast and
05:12you know if you want an exciting ride then it can it can give that okay that's really interesting
05:17because I'd say that's in pretty stark contrast to what the Domane has been feeling like to ride
05:23I would say that actually it kind of wants me just to stay in the saddle when I do get out the saddle
05:28and try and you know throw it up a climb or get a little bit more aggressive it always makes me
05:33feel like it wants me to calm down and just sit in the saddle and just turn the pedals turn the
05:38watts out and it's something that kind of makes the bike feel a little bit lazy so it sounds like
05:43between the Domane and the Synapse actually the Synapse may lend itself slightly more towards
05:49those that do want to kind of be a little bit more aggressive rather than doing pure endurance miles
05:55why do you think it is that the Domane doesn't want you to push it really?
05:58It's a really good question actually I think there's probably a couple of things in that
06:02not only do you have the IsoSpeed technology so obviously that in itself does make the ride
06:09itself quite comfortable um but I think it's also the geometry of the bike so you've got
06:14um pretty decently long wheelbase it's over 100 centimeters from sizes 50 to an up and then you've
06:20got a pretty slack head angle as well because that's around about 71 degrees across the size
06:26range and obviously that does differ from size to size but it's all generally around 71 to 72
06:30when you do get out the saddle and you do stand up I find the the slackness of the head angle
06:36does just put me back down again that's how it's felt like to me oh that's pretty interesting
06:40because the Cannondale actually has the in the size 56 which I tested the wheelbase is just under
06:44100 centimeters so it's still got the kind of short responsiveness but it that's not to say
06:49it's not stable as well probably due to the front end the one thing that I didn't mention just then
06:53was that the Cannondale is actually quite heavy it's 9.5 kilos for that size 56. How does that
06:58compare with the Domane's weight? Well so the bike that I've been riding actually is in a
07:03specification that isn't available to buy so we don't have a direct comparison for the bike that
07:08you were riding and the bike that I was riding however if we look towards both Dura-Ace models
07:13of the bike there's a very big difference here so the Domane in the SLR version of the bike which
07:20uses their 800 series carbon that bike comes in at 7.25 kilos well and I believe the Synapse in
07:28its Dura-Ace configuration comes in at 8.3 kilos that's right yeah now there's a couple of caveats
07:34to this obviously the SLR version of the Domane will have that 800 series carbon and the Synapse
07:42does have SmartSense as well which is potentially going to add around 500 grams according to
07:47Cannondale so that's where you're going to have a pretty big difference in terms of weight but
07:53even if you strip away that 500 grams from SmartSense you've essentially still got this 500
07:57gram difference which can either be pegged towards the carbon that's used on the frame
08:02or perhaps the components that are used down to kind of wheels and tyre choices. Yeah like you say
08:08Trek uses the 800 series carbon for the top bikes whereas the Synapse just gets one carbon frame for
08:13all the models for all the Synapse carbons. Yeah absolutely so one thing that does make a big
08:18difference to how a bike feels is of course the tyres what was your Synapse running? Well
08:23unfortunately it comes with quite low end tyres the Vittoria Rubino Pros in a 30 millimetre size
08:28so they're quite big tyres and if they're cheap which they are it means they're going to be a bit
08:32heavier they're going to add quite a lot of rolling weight. Yes absolutely so I guess it's not
08:37only the rolling weight that's going to kind of bring it down but it's also the suppleness of the
08:43tyre as well because those Rubinos are actually quite harsh and they don't they don't kind of
08:47offer much so you can look at that either way obviously most people do tend to change their
08:52tyres over time but it means that you know there's potentially quite a big gain to be had if you were
08:58to upgrade your tyres say for example to some of the GP5000 either in a 30 or 32c size you would
09:04actually potentially feel quite a vast improvement in the ride quality. Absolutely and I think the
09:09other thing about the Synapse or in that build that I had which is the Altegra mechanical build
09:13is that you get these quite cheap heavy wheels which are Fulcrum Rapid Red 900 so I think they're
09:19just an OEM wheel and if you change the wheels as well upgraded the wheels and then you'd lose
09:23some weight and get a better ride quality with those as well.
09:31We'll move on to aesthetics now and that is of course something that's quite subjective
09:35but what do you really think of the Synapse's look? Well okay so it's got an angular kind of
09:40look I mean it's it's all straight tubes and I like that I like the straight angular tubes a
09:44very compact main triangle very heavily sloping top tube and drop seat stays underneath that so
09:50the Synapse frame is all about responsiveness and comfort because you've got the long
09:54seat tube and seat post. Do I like the look of it? I mean I think it's not particularly striking I
09:59have to say but I think what is striking about the model I tested is the beetle green colourway
10:04you know you see a sort of an ordinary looking frame with the straight tubes and you think oh
10:08that's just another bike but the beetle green colourway it looks sort of green but in the
10:14sunlight it turns into this coppery bronze colour so it's a really nice little twist and something
10:19that you don't really expect. I quite like the way Cannondale has kept the logo small so you've
10:23just got you know it's not sort of huge branding all over it so so yeah I mean I have to say I like
10:28the look of it it's not the most exciting looking bike ever but the paint is quite exciting. No
10:33that's really interesting for me looking at the Domane I'd say in some ways it's it's a bit of a
10:39weird thing to say but it's a very bike looking bike you know there's nothing really offensive
10:44about it but at the same time there's nothing really super inspirational about it. I think it
10:49looks quite elegant I like the it's it's a little bit curvier than the Synapse I think it looks to
10:54me like quite an elegant bike. Absolutely I mean I'm a really big fan of a classic bike frame shape
10:59I do love it when a bike doesn't have drop seat stays and I do like the sculpture on the head
11:05tube as well it's something that you do see across a lot of the Trek models so it's nice seeing that
11:09kind of design language you know being consistent across them and then one other thing that I will
11:14mention is that on some of the other Trek models like the Madone and the Émonda you do get a really
11:19big Trek decal logo on the down tube whereas on the Domane it is just a little bit smaller which
11:25is nice it's still large especially comparatively to the Cannondale but I think they've gone for
11:30a really nice set of color schemes just really bold colors with a pretty unoffensive looking
11:35logo and the frames just generally look pretty clean. So Simon is it fair to assume that we're
11:41in agreement that we both prefer the look of the Domane? Yeah I think in terms of looks it has to
11:45be the Domane for me. Yeah me too. Finally we are going to discuss the build options and the value
11:55that those represent and actually I think they make for a really interesting comparison because
12:00the Domane is available in so many more builds and that's because you can buy the Domane with a SRAM
12:07groupset whereas at the moment you can't do that on Cannondale. So run us through Simon what do
12:12you think about the Synapse's build options and the value that they provide? Okay so first of all
12:18I've just got to say that the one that I reviewed which was the Altegra Equipped 2 RL is £900
12:23more expensive than the outgoing Synapse and that sounds like quite a lot of money and I'm guessing
12:27that that is probably to recoup the costs of the R&D, the SmartSense and the new bike
12:34you know that's mostly where the costs are going to be. But actually if you look further down the
12:37range it starts with the AL, the aluminium versions and those bottom three are actually
12:42looking like quite good value for money I would say. You've got versions with Sora Tiagra and
12:47Mechanical 105 and they come without SmartSense but they're still SmartSense compatible. Then
12:52there's one Synapse Carbon that comes without SmartSense and that's the only one as we mentioned
12:57earlier. Sounds crazy to say but the higher up the range you go the better value it looks. Which is
13:02genuinely mad to say but this is the thing when you do compare it against the Domane which
13:07at the moment is what we're using as the point of comparison, the gaps become even bigger so
13:13at the bottom for the Sora Equipped aluminium version of the bike you've got a difference of
13:19£150 here in the UK. However when you get to the top end and you look at the Dura-Ace Carbon models
13:26you've then got a difference of £3,500. That's absolutely huge. Why do you think that is?
13:33It's hard to fathom actually because I think for any bike the flagship model with Dura-Ace Di2
13:41is normally going to be more than £9,000. This day and age yeah which I mean in itself is another
13:46point of discussion but like you say to get the range topping bike for you know four figures
13:52I mean it's not amazing but comparatively it's much better than the Domane. It is but actually
13:58I wonder if that's because as we said earlier there's just one carbon frame across all the
14:02Cynelapse models. They're not using a sort of super high modulus kind of very super light thing.
14:07Maybe that's part of the reason? I think that could be to come. As we know we have seen Lab 71
14:12bikes coming out of Cannondale very recently. It was launched with the Super 6. There's now the
14:17Topstone. It's pretty clear that they're using moulds that they already have so you know either
14:23maybe towards the end of the year or next it would not be a surprise to see a Lab 71 Cynelapse.
14:28So then it brings it up to the expected flagship price of £14,000. Yes exactly well and actually
14:33since the very top end Super 6 is £12,500 once you've mated that spec to a Lab 71 bike
14:41it would then be potentially matching the Domane exactly pound for pound. As I mentioned at the
14:46start the Domane does come in far more build options and I think you know we've discussed
14:52the top end it far exceeds the cost of the top end Cynelapse. However down at the other end with
14:59the aluminium builds the Domane does come in a Claris version whereas the Cynelapse only starts
15:06at the Soarer level. However there is again a caveat to this because the difference between
15:11the Domane Claris and the Cynelapse Soarer is only a difference of £50. So actually you could
15:18spend an extra £50 and then get yourself up by a whole group set level which is actually quite
15:24enticing. So I'd say those two bottom levels they're very similar money in terms of allowing
15:30yourself to get onto that platform but working up through the range with the Domane it is really
15:36nice that you've got smaller jumps and you can really fine-tune exactly how much you want to
15:41spend. If you have a budget there's a very good chance you're going to be able to find a Domane
15:45that suits that budget. So summing up what can we conclude from everything we've talked about so far
15:52about these two bikes? Do we like them? Do you like the Domane? Well I do like the Domane and I think
15:58as an endurance bike it is a fantastic tool for that job. If you do want to do some really
16:05comfortable really relaxed miles you know go and crush your first 100 mile sportive this is a
16:10brilliant bike to go and do that on. I love the fact that there's a huge range and essentially
16:15everyone can find a bike that suits their budget I think that's brilliant. As we've already mentioned
16:20we both really like the looks of the Domane it's just a very clean unoffensive nice looking bike
16:26you really can't get around that. I think the only thing for me is that as someone who does prefer a
16:32more performance orientated ride feel that's the only area in which I would say the Synapse
16:37clinches it. But what about you Simon what what do you think between the two bikes? Like you said the
16:42performance aspect is something that's quite important if you're after a sort of a racier
16:46bike if you like a racy ride feel if you like a fast bike then I think the Synapse has it but for
16:51me I would like to I would like it to be a bit lighter so I think I would have to do some upgrades
16:55on it it would need lighter wheels and lighter tires and I would go for a size down I would
17:00choose a smaller size the 54 and put a longer stem on it so that I had a more aggressive position
17:04instead of being so high at the front end. But the ride feel is great it is fast as a riding bike
17:09it's I do like it yeah. So I think we're pretty much agreed then in terms of what the bikes
17:14actually like to ride and what it feels like we'd both opt for the Synapse but in terms of aesthetics
17:20features and then just the sheer range that's available the Domane kind of wins in those areas
17:27so it's a tough one it depends what's important to you let us know down in the comments which bike
17:32would you go for I'd be really interested to hear all of your thoughts if you enjoyed the video then
17:37please do drop it a like subscribe to the channel for more content and we will see you again very soon
