I’ve had the new Look for a few months now and agree with most of the things said by Josh Ross in his review: Look 795 Blade RS review: The climber's aero bike | Cyclingnews
Unlike Josh, I did not find the seat angle adjustment “maddening”, and did manage to get <7kg for a size M (albeit with THM cranks speedplay nano pedals). Josh’s overall conclusion:
Instead, this is a bike that feels fast. I never feel beat up by it but I’m not going to pretend this is an easy bike to ride. I’m happy with a deep bend and my arms stretched out. If you aren’t, this might not be the right bike for you. This is a bike that begs you to slam the stem, weigh every part, and ride it hard. It’s a race bike through and through and the harder you push it the more it seems to want. As long as that’s what you are looking for, you are going to be very happy.
I came from a Tarmac SL-6 and Supersix Evo before that. Both were great bikes, and both much lighter than the Look. You definitely notice the ‘free speed’ that comes from a more aero-focused race bike, but the same would apply to the SL8, 4th gen Evo, and other modern ‘all-round’ race bikes. To me, the bike isn’t as agile or playful as the old SS or SL6, and that may just be weight-related. The Look is stiff and responsive, but not uncomfortably so (w/ 28mm Vittoria tires). In saying that, I have enjoyed every km ridden on the Look and love the design of the bike w/ the mondrian theme - it’s definitely a beautiful bike:
The build quality is impressive, and all the little finishing details seem well-thought through.
There are some other first-hand accounts of the Look starting to trickle through on the WW forum: New Look 795 Blade RS - Page 6 - Weight Weenies
