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.
I've been road cycling for years but want to explore some gravel riding and touring. Not wanting to mess with my position on the bike and pedals, it was nice to have the option of the shorter axle to keep the q-angle unchanged from my road pedals. The difference in stack height is less than a millimeter, so no significant change there either. There's a little more float but that's manageable. The pedals hang just right for consistent clipping in. I'm pleased with the transition, although I do miss the large contact area of my road pedals.
So I'm an old guy (72) been riding and racing since I was a teen. So for quite a while anyway. These are the first TPU tubes I've ever run on my bikes. I like them, it's only been a couple months but they're lighter and I think maybe roll faster than butyl tubes. I've had no flats and no problems with the valve stems working with the stem extenders my wheels require. I'd recommend them.
