Road Cycling “It is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them.

Cannondale six vs synapse???

I definitely want a Cannondale. I'm confused about whether to get a feminine synapse carbon or a six?
Synapse carbon are listed under "performance", Six is listed under "elite". Can someone explain the difference in the lines to me in simple terms? I want to get into this sport hardcore so I can keep up with the big boys.

Here's links to the bikes I'm deciding between:

Thanks.

Well, first of all, just from the two links you posted, I'm going to assume that those are the two particular Six/Synapse models you're interested in.

The first most obvious difference is in the component spec. The Six Fe*****e 1 has WAY better components than the Synapse Fem 5 that you posted.

On the Six Fem 1, you have an aluminum frame with carbon seat stays and chainstays. Seems more like a bike you would bring to a race, compared to the Synapse, which seems like it was made for long rides. The frame on the Synapse is all carbon I believe.

Additionally, the top tube on the Synapse slopes down significantly more than the Six does, so it would give you a more comfortable, relatively laid back ride, however sacrificing a bit of your positioning advantages should you want to race, or just go fast...

In simpler terms I guess, in my opinion, out of those two choices you posted, go with the Six. If your plan is to keep up with people, you probably want a bike thats geared more towards racing than comfort. Not to mention it just looks better and is specced WAY better than the synapse you posted.

The most notable thing is that geometry on the two frames is different. The Synapse has a much more relaxed geometry than the Six and the head tube lengths are different the angles etc. They carbon layup is different. The Six is a race bike the Synapse is a fast sport bike.

It's almost six of one, half-a-dozen of the other...

The Synapse was designed since its introduction as a smoother-riding road bike. The Six -- and I mean this aluminum-carbon version -- seems like it's built to placate the riders who want a frame like what so many others make, which is an aluminum front and carbon stays.

Despite the sloping top tube of the Synapse, the geometries are really close where it counts -- head tube and seat tube angles, wheelbase, etc. The Synapse does indeed have a slightly taller head tube in some sizes, yet it's actually a little steeper, which is supposed to give more responsive handling.

If you're a strong rider, you might sense more frame flex on the Synapse, such as when standing to sprint or climb.

But, again, these are so close that any differences would be difficult to quantify, and even if they were being raced, I'd think that any bike differences would be overshadowed by the skill and fitness of the riders.

For the rest of us, it's pretty easy to choose -- just get what you like. At this price range, nothing sucks. And, considering how much costlier the Six 1 is than the Synapse Carbon 5, I think a more apt comparison would be between the Six 1 and Synapse Carbon 3 or 4.

No, I'm not a strong rider. I'm just beginning. Considering the fact I've never had a road bike before, I guess I've made a better choice with the Synapse. I want to be able to do long rides (to me that means 60 miles) and not have my back kill me like it does on my flatbar hybrid after 30 miles. I do want to be able to keep up though too. Thanks for the comment on frame flex. All this time I've been shopping for a bike and I didn't know what they were talking about when they said one was more stiff than another. lol For this much money, I'd really like to buy the appropriate bike.

The Synapse is designed to flex vertically. That's what gives it some of its shock absorption and is part of what makes it a "comfort" road bike as opposed to a stiff-as-a-board racing bike.

The Synapse will, in addition to riding a bit more compliantly, not steer as quickly or be as "twitchy" and its design will mount the handlebars higher and closer to the saddle and make it easy to mount them yet higher and closer.

A race bike like the Six will have a stiffer ride but will accelerate more quickly under a stronger rider, will have quicker steering, and mount the handlebars lower and farther away from the saddle. You can mount the handlebars higher and closer to the saddle but the frame's design will limit how high and how close.

There are many on this board who ride racing type bikes, e.g. the Six, for long distances and durations and you can too but I think you'll find the Synapse to be a better first road bike.

One small piece to take note of is the taller spacer on the Synapse's steerer, which is seen right on top of the headtube.

Naked (that is, without anything installed), both frames have basically identical head tube lengths. However, the taller bottom spacer included on the Synapse helps to raise its handlebars a bit higher. What that also means is that, if you ever want to put the handlebars really low, you'll be able to do it.

Again, though, we're picking nits.

fwiw there are also many in my neck of the woods (and possibly on this board as well) who ride a Synapse for crit racing. And you can too. The steering on the Synapse isn't quite as instantaneous as it is on a bike with a more aggressive geometry, but there's nothing about either bike that's inherently Too Slow To Race, or Too Uncomfortable To Go Long Distances On.

The one thing I've never quite understood is why people who don't race buy a bike with full race geometry. They end up with a massive amount of spacers and flipped stem because they can't ride anything more than a 1.5" drop. I'm sure it's cool to have a full race bike in your garage but a bike like the Synapse is so much better suited for fast recreational riding and much more comfortable as well.

^^^^ Because race-ready bikes are so much easier to find than, say, touring bikes.

Yeah it's nearly impossible to find a Specialized Robauix or a Cannandale Synapse or a Giant Defy. If only your LBS carried these hard to find brands.

Those are all reasonably race-able. It's rare to find something like a Long Haul Trucker in the flesh on a shop rack, though; and Cannondale's heavy-duty touring bikes aren't even sold in the States.

Race-able yes. Race geometry no. Big difference.

Just thought of this as I was riding my CAAD8 back to work today --

Why not use a bike with race geometry? I could've ridden my Bianchi Valle (flat bar steel city bike), my FS MTB (it's like an SUV ), or my 'cross/rain bike, but I took the CAAD8 'cuz it's just so much fun to ride.

Besides, the Synapse has been raced professionally, so it's not like it's not race-worthy.

Thanks again for the advice. I SO trust my LBS now. I called and spoke to the owner about it, and he could have easily had me shell out another several hundered to get the other bike and get my money sooner. He spent a long time on the phone with me and said just wait for your synapse, you'll be very happy with. I'm sure they think I'm koo koo. Oh wait...I am.

Dude what part of my post confuses you. The synaps and the Six have different geometry. The Six is full race the Synapse is more relaxed. Christ you can race a long haul trucker. My post about why people buy a bike with full race geomtry and add a ton of spacers and flip the stem up is odd to me especially when there are plenty of bike to chose from that would be better suited for the type of riding those people will do.

Looks like you are approaching this the right way as far as your goals. I am sure you'll do fine on both goals. The HHH is still one of my "goal" ride/races, I had planned to make it my first 100 mile ride. I started cycling while stationed in Shreveport, LA and it was one of the first events I found out about. I was relocated shortly there after so I haven't made the trip to do it yet. I had actually planned to go this year but am in the process of another move, and unfortunately I keep getting further away...

I just made a similiar decison and went with the Synapse. I am new to this and realized that I just need a bike I can get out and ride comfortably. I am not in the TDF and may never race. One day I would like to enter a race but for now I just need to ride to build my strength and learn how to ride effectively. After I start accomplishing these goals and learn more about what type of riding I want to pursue and what I like in a bike I will move on to a different bike if I think it is justified. For now the Synapse seems to be a great fit and I am enjoying the riding experience and experience is what I need right now in the early stages of my riding career. If I find I don't ride too much in the future due to other interest and my busy life at least I have a bike that is better suited than an all out race bike that won't ever race. For now I will watch the Giro and TDF and dream of being LA (or whoever you are rooting for) when I am out riding. I bought the Synapse 5 AL for now as a starting point as I figure in 3-4 years Carbon will be much cheaper and with the dawning of electronic shifters Dura Ace componants will be cheaper to. In 3-4 years I will know if I need to step up to a higher level bike and by then have enough sense to know what I want and why I want it.

Can't believe you're getting so pissy about bikes that are fun to ride....
