Overall I'm very pleased

I have been riding a Tarmac with Ultegra mechanical group set. The Ultegra di2 is a major upgrade. Having wider tires and a longer wheelbase improved the comfort of my ride significantly. Axle to axle the Look 765 is 2 inches longer than my tarmac.

In a size large this bike came with 110mm stem and a 135mm saddle. Both had to be changed. I also dropped the bars a little. This required shortening hoses which was done at local bike shop after fitting.

After the changes i am really enjoying this bike. I ride mostly on paved bike trails and country roads. It rides smooth and quiet and looks good too.

Thank you for your feedback.

fast comfortable endurance bike

As an aging rider I'm looking for comfort, but still want a bike that is light and stiff enough. This bike perfectly meets my needs. I just bought it in November and live in the Oregon cascades, so only about 250 miles on it. It climbs very well and so stable on descents. Wheels are a little heavy, but very nice ride and I switched handlebar for a carbon I already owned. Otherwise, no other changes were made. The Shimano system is excellent.

Thank you for your feedback.

Great bike, great components!

This bike with the Di2 Ultegra group set and the carbon fiber wheelset has everything that I was looking in a bike. I'm not a competitive racer, so this frame geometry suit best for longer bike rides. The frame is light and the Di2 shifters are nice. I bought this bike on sale, so that is a plus. I'm very happy with the bike and everybody says that it looks amazing!

Thank you for your feedback.
