Look2025 765 Optimum Shimano Ultegra Di2 Bike(Return to Product Page)

The bike is fantastic, it has just the right amount of stiffness and give to make longer rides comfortable, but the bike is responsive when getting on it.

Since I was in between a Medium and a Large frame, I ended up replacing the stem with a 20mm shorter one along with the handlebar to a 46cm CF one to make it the perfect ride. Added a couple water bottle cages, some Garmin power meter pedals, computer, speed sensor, and lights and it is ready to go.

The CF wheels and DI2 system are fantastic. The only thing I wished for were additional frame colors, but all that is available is the grey/black, so the new handlebars got some orange tape to make the bike a bit more visible.

Here is to many more miles and smiles.

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.

This bike and build is fantastic. Vibration-damping carbon frame, fast stock carbon wheels, precise shifting with Shimano Di2 12 speed Ultegra. You get $1000ish carbon wheels and a $2200ish groupset at this very nice price. No regrets.

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.

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!
