Super quality, super stiff, excellent bottom bracket, chrome looks great on my bike. Length gives me power to stand and drive over climbs. Impressive power numbers on the trainer (hold 400watts on 10 min long climbs). Still trying to get used to the change in gearing. Really need close ratios as one shift makes a huge difference. I see these good for strength training and stretching out, but I cannot get a sprint going on them and struggle to hold wheels in motor pace sessions at 50km/h. Mainly because going a bigger gear takes a while to get back on top of it. Changes of speed are more difficult. Hard to stay smooth above 85rpm. On my fav climb I am doing 70rpm (3-6% climb @ 4km long) at >400 watts = above 20km/hr which is great for me. I am back to the shorter cranks for racing. These for strength sessions. 3 stars, the quality of the cranks and bearings are 5 star though.
