Strong, and fairly light.
Scott customer service is excellent.
conservative aero design.
airfoil tubing.


Very tight tire clearance on chainstays behind bottom bracket.
Slow acceleration.
Exposed cables.
Stock bars could use an upgrade.

I have been using this bike for more than 2 years now so have had a good amount of time to pick out its strengths and weaknesses. With that said... I still own it! That says something right there!

Right off the bat, you notice that the shape of the bike isn't the most radical around. In fact, it's almost identical to those ebay carbon TT frames. However... that doesn't mean it isn't fast.

It may not be proven to be as fast as a p4 in a time trial, but it certainly doesn't make you slow. The frame is aero, and tubing is in an airfoil shape pretty much everywhere. It's a conservative TT frame (if such a thing exists)

The stock aerobars could use a little upgrade - do yourself a favor and chop off the ends of those bullhorns so that your base bars lay flat. I find it much more comfortable and it's faster.

Previous reviews have made comments about the seat mast - it's true, adjustments are made with a saw, and once you cut you can't go back. However, scott does offer a replacement seat mast with 50mm of adjustment compared with the one that comes stock with 25mm of adjustment. So if you cut it short, you always have another option.

The ride? It's fast. Obviously any TT bike is going to be faster than a road bike, and this is no exception to that rule. If you want to gain a couple mph, invest in a TT bike.

Climbing? Surprisingly, not too bad. The way mine is configured I often hit my knees on the arm pads if I'm not paying attention, but such is true for most TT bikes. It's not slow on the climbs, though.

Accelerating, it's bad. But it's what you'd expect from any TT frame. They're meant to go fast and stay going fast, not accelerate for sprints. Unlike a quality road bike where you feel every effort go straight to your wheels, it's very sluggish off the start. But once you're up to speed, no problem.

This isn't a review for the groupset, so I'll just say - it's 105. It gets the job done well, but weighs a little bit more than if you went with dura-ace. But it's a TT bike, weight shouldn't matter quite as much in this case.

The frame is solidly built, however there is one gripe I have. The clearance right behind the bottom bracket on the chainstays is very tight. With 23mm tires, I have less than a few mm of clearance. If you were to use 25mm tires, they probably wouldn't clear the frame, especially if your wheel was knocked untrue.

All in all, it's a solid bike. The geometry is very well suited for a TT as well as a triathlon where you're spending more time in the saddle.

With all the new aero regulations coming out, my bet is that manufacturers will start to go back to this more conventional aero frame design, and for good reason - there's nothing wrong with it.

Speed, vibration absorbing frame, speed, fit & finish, style


Integral seat post means adjustments are made with a saw (yikes!) although there is a few cm of adjustment in the seat mount.
This saves a lot of weight - so not a bad tradeoff

I picked this up at Boulder Cycle sport after a very thorough fitting and it arrived a few days later from Scott looking way more radical than the pictures. The shaping of the carbon tubeset lets you know immediatly this is a bike for speed.
The Carbon frame sucks up bumps and road chatter far more than I exepected and, once you get used to manuvering at slow speeds the bike tracks very well.
When you get it out on the open road and put the hammer down - Holy CRAP! This added 2-3 MPH to my average speed - and it is even a bigger difference on the downhills. Want to hold 35MPH for a mile or two after coming off a hill? Just keep your head down and mashing that big gear.
This bike is well laid out, the Shimano drive train is flawless and is a comfortable place for a long day in the saddle - although since you will likely set a PR , it won't be that long
