The actual bike ~ frame - adjustability, TT et up is great, however the wheels that come with this bike are a disaster. They are heavy and do not roll like other carbon wheels. They are apparently suitable for both road and gravel use ~ so a bit of a bizarre choice for a triathlon bike that you are never going to use off road or through the winter. I had my most difficult and slowest rides on this bike until I borrowed the wheels off my other halves Shiv - CLX64’s and it was like riding a completely different bike. However this leaves a difficult decision, do I save up and buy new wheels or cut my losses and sell the bike. Very disappointed.

Hands down this is the fastest bike currently on the market, and for the 1% of triathletes not immediately sold by that fact, the news gets even better, specialized has worked some of their black magic on this bike so that even with all the integration keeping you comfortable and slippery through the air all race long, its also a dream to dial in your fit and keep that fit locked in through transport to race day. Im not here to tell you its an amazing climber, but its still able to grind up at least a 15 degree incline even carrying an extra liter of water on the bike, and while its not optimized for quick turns and acceleration, the stiffness and power transfer you get on this bike let you put the hammer down exactly when you want to, without a moment hesitation. Bottom line this bike is freaky fast without being a diva to take care of. PS the other two reviewers or other Shiv Disc owners, if you get the 25mm offset seat post instead of the 0 offset post that comes stock, you get another two inches of clearance to bring the seat down without having to do anything else to the bike (I was also running into the same issue of incompatibility between my fit specs and the stock seat post/fuelcell.

My first trip bike. Long time cyclist, just getting into triathlons. It is very fast and quite comfortable. To Sam (the previous reviewer), I had the same issue with the water cell, but my bike store was able to cut the box/sail/fairing/ water tank to make it work. I did upgrade the wheels to CLX64 with Turbo Cotton's and the ride quality was excellent. Rode 66 miles today in 10 mph wind - 3 loops so for wind in every direction, but the bike felt rock stable and quick. A proper fit is key, but this is bike is so fun and fast, it should be illegal. Minor issue - lost the rubber lid to my hydration system on the drive back. I think it got disconnected from the base at a rest stop and the on the drive the thing fell off. Need to buy a new one now and figure out how to drive with it when the bike is mounted on the hitch.
