Strengths:    Smoothness and responsiveness of ride. Great gears and the carbon frame seems to take the stress of bumps away so they are mostly not noticeable. The bike is really fast and a joy to ride. Well worth every cent I paid.

Weaknesses:    The lighter frame in crosswinds. Doesn't happen a lot but when the wind is strong, I am not heavy, so I need to hold on really firmly. Only major problem would be in a crash with the carbon frame; very difficult to repair.

Bottom Line:   
My current bike is a Trek Madone 4.5 WSD. It is a wonderful bike. The frame is light and the bike is extremely responsive. It has a full carbon frame and the ride is really smooth, even on bumpy surfaces. It corners well at speed and going up hills is a dream. My bike has Shimano 105's on the front and Ultegra on the rear. The gears shift really smoothly. Even on longer rides over 50 kms, it feels easy and the bike does most of the work, so riding is a pleasure. I would recommend this bike to anyone who wants a really good ride and for people who ride long distances at a time. Even on my usual 50 km ride, it is a dream and never disappoints. A very reliable bike.

Favorite Ride:   Subi to Freo and back

Price Paid:    $3200.00

Purchased At:   Rider's Choice, Leed

Similar Products Used:   None really. My old Indi Condor had a steel frame, but it was a very responsive bike for its time and was also a real joy to ride.

Bike Setup:   Carbon frame, Shimano groupset with 105 on the front and Ultegra on the back. Changed the saddle to a Selle Italia and the tyres to Gatorskins because of flats. Powerful 900 lumen Nitelight for dark mornings around 5 a.m. and generic brakes with calipers, not disc brakes. They are fine. Bike has been fitted properly to my frame.

Strengths:    Price is good for what you get. Strong, reliable frame. Appearance is attractive. Fast ride. Holds up well in wet weather but a bit shaky when it gets windy.

Weaknesses:    Gears keep dropping out after a short while and need servicing. A bit shuddery and vibrates quite a lot over rough road surfaces; a bit uncomfortable on the rear end. Not as responsive when going down hills and around corners at speed. Not adjusted for a woman's frame, so more suited to a male. Tiagra and Sora components aren't too bad, but you really get what you pay for.

Bottom Line:   
Is actually 2009 model with standard Tiagra and Sora components. I bought the bike after not being on one for over 20 years and the new technology was noticeably better; faster and smoother ride, since my last road bike was a steel Indi Condor. The bike is fairly responsive but rattles a bit going over bumpy roads. Gloves help to absorb the vibration. It is fairly stable on flat road surfaces but isn't so responsive around corners. I changed over the original tyres due to a problem with continual punctures. Changed them to 'Flatfighters' which mostly eliminated the puncture problems and I would recommend them highly. The bike is fairly light and fast, but not really designed with a woman's anatomy in mind. I have ridden this bike over 8000 kms in the year since I bought it. The Tiagra shifters work quite well but are sometimes not really smooth and the gears tend to drop out occasionally when I put my foot down. Then my whole posture shifts suddenly which is not really comfortable. Lucky that I have very good balance. The bike has had to go for servicing probably more than I would like, simply to correct the gears from dropping out. Overall, the bike is good for someone wanting a reasonable road bike at a manageable price. It is solid and reliable and will give a good and fairly fast ride. I wouldn't be going around corners too fast though, because it's not so responsive and downhill, it gets a bit shaky at speeds over 35 kph. Recommended for riders who have some experience and want a decent road bike for recreational use.

Strengths:    Overall a great bike.

Weaknesses:    Saddle is a bit harsh.

Bottom Line:   
This bike is well worth the price. I like the frame geometry and the 105 components work really well. I had no assembly issues like a previous reviewer although there are some unique sounds from the crank that I had to get used to. I used to ride a lot and then turned into a couch potato. After dropping 200 pounds I got this as a present and it is the best, most responsive bike I've ever had. I'll never have a really high priced bike and this is the bomb at this price point.

Strengths:    Full Shimano 105 components, but require lots of adjustments.

Weaknesses:    Poor Quality. Bad assembly. Missaligned mechanical parts. Lack of Giant customer service. My Miyata has 30,000 miles never adjustments (not even cables), all original, no noise, rides like new. Giant makes all kind of mechanical noises and part of energy goes towards overcoming the friction. Kind of bike you will buy at Target.

Bottom Line:   
It's actually 2009. Bought new in the box. Bike makes all kind of grinding, squeezing, metallic noises regardless of gear selection. Brought back to the shop 8 times within 3 weeks. They were keep adjusting front/rear derauilers cables... Was very frustrated. No way to escalate to Giant, they don't have customer service. Forced to deal with Giant dealer. Finally mechanic took bike apart to bare frame. The BB, crank were not assembled, lubricated, and tight up properly. Unbelievable. was told it's a common problem with new Giant bikes. Bad idea to buy Giant bike if you not a mechanic. I'm not happy with the bike and Giant.

Out of all new 2009 bikes I tested, Rubauix stands apart as class act. Giant was discounting and dealing, but you got what you paid. I would only consider products from Speci and Trek (as 2-nd choice)

Strengths:    Geometry, light weight, solid components.

Weaknesses:    The seat. I took my own and I'm glad I did.

Bottom Line:   
I rented this bike for a week ride in the Alps. I normally ride a Lemond Zurich and was a bit concerned about riding an aluminum bike with 105 instead of my normal Ultegra.
No worries. I liked the geometry better than my Lemond; the bike was light, stable and a good climber; and the vibration was no different than I was used to. We climbed a range of cols that are on the Tour de France, and I had no trouble keeping up with those who brought their own bikes. I was impressed.
