Stiffness and out and out pace.

Noisy

A fantastic bike. I bought mine from a collegue who always buys the best of anything. It was small for him at 6'5" but for me its perfect at 6'1". The short stiff back end makes the accelleration fantastic and I have not found the weight a problem on hills and we have plenty around here! It is fairly standard all bar a dura ace rear mech and works beautifully. I would recommend that you try one!

Aero and stiff Price--find one auctioned and grab a deal! Fit, my back is completely flat and I feel comfortable in the aero position

Slack seat tube a problem in du''s/tri''s? Welds a little chunky Stiffness could be a problem in Ironman-length races A little heavy for hilly/rolling courses (like all dedicated TT bikes)

This review is for medium Vengeance. I''ve been wanting a dedicated TT bike for some time now and when this opportunity came up, I couldn''t resist (everything stock for that price!) Please see my review for the bars in that section of this site, I''ll stick to just my impressions of the frame. Overall, this is one wicked fast, stiff, aero frame with one thing in mind: speed. It is a bit heavy for climbing, but you usually don''t find a lot of climbs on a good TT course. If you do, I suggest a light road bike with clip-ons. The 650C wheels combined with the laid back geometry create a very smooth and stable ride, even in a full-on aero position. The bike is nimble enough to take emergancy action if need be, but is just fine going straight. Sitting up and riding no-handed is a bit dicey, though, because a side wind can knock you around easily if you''re not careful. The seat tube angle is like a traditional road bike: around 74 degrees by my reckoning. I feel ok with this since I''m a road racer primarily, but I''m not sure how it''ll feel once I start doing some duathlons and running right off the bike. Everything on this bike is aero, including the seat stays and the seat post. The cables are all internally routed to keep the airflow clean and the bike looking nice. There are 2 water bottle braze-ons: one on the front of the seat tube and one on the back of the seat tube (under the saddle, above the level of the top tube.) The one on the back of the seat tube is a bit tricky to reach, especially while you''re legs are moving. One caveat: I''m 5''7" and 180# so the medium is little on the large side for me. It has a 55cm TT and the seat tube is an airfoil shape with a proprietary seat post and seat clamp. The seat post is a BMX 25 mm seatpost with an airfoil extension of the seat tube which means that it only goes down so far before the aero cowlings meet. I had to put a standard 25 mm seat post in the seat tube to get the seat low enough. The welds of the frame bear mentioning. They are the usual-for-GT chunky TIG beads but for a bike of this type and level, I would''ve preferred filet brazing to smooth out the transitions. It''s a shame that all the other aero bits are thought out but then they are these big, rough looking welds.

Lightweight and sturdy the frame is of the highest quality. Due to age you can get one fairly cheap. My bike has 600 comps so I can''''t say anything for the 105 that came with the bike, but overall the bike is great, I have no complaints.

None that I can think of.

Overall I absolutely love the bike. Incredibly light and in great shape it has truly been a benefit to my racing. Considering the frame is almost 3 years old, you can get an incredible steal on an incredible bike.

very aero,light,good on hills

headtube has alot of slack so steerer tube does''nt stay firmly in place it jiggles back and forth over bumps,seat clamp creeks all the time grease or not...and the mavic cxp 21 wheels suck..broken spokes every other week.

my bike is a giant aero it is very fast.. but the seat post area creaks all the time but i like it seems like a good foundation for upgrades.

Great cornering speed. Feels fast, ridged frame rides very well.

Only one space for a water bottle. For the price of the frame you would either like to have it custom made or at least a choice of what colour you wanted.

This is a ferrari the best bike I have ever riden. Never buy a carbon fibre bike again after the Giant CRF-1. For the first month I had to be careful because it feels so fast that when you corner you think your on a razors edge. Cornering speed increased greatly once I became use to the way it handled. Great for climbs and triathlons.

have used it for 1 ironman and 6 half ironman. With over 15000 kms clocked up it is still going strong.

Stiff, light and aerodynamic frame but still comfortable on longer rides. Great for triathlon.

Seat tube angle is not 78° which is normal on tri-bikes. This may mean less power but more comfort.

Nice bike for triathlon, affordable. If you got more to spend the GT Vengeance might be an alternative (even more Aero).

This bike is arocket, it feels, so fast and you can really feel the frame picking up in the wind.
I cannot believe that a bike can feel this stiff and still be comfortable to ride in big TTs and Triathlons

Perhaps a little on the heavy side for big hill races
It can catch the wind a bit if it is a big side wind

I love this bike and it propelled with out aero bars to a top 20 finish in the final stage of the 2001 speights Coast to Coast, over 70kms. The wheels and frame where flying that I averaged over 45km for the first 45min of the race
I would love a superlite version.

I would reccommend as a great TT set up, or Multisport race bike for flat rides, a little beefy on the hills. I use a Dean Al on hill races
