Hello Experts,
Im not total happy about my tt fuji bike. After bike fitting I dont fill like its fully comfy to ride and I'm not sure why is that..
I'd like to update my bike by some non-expensive upgrades to race a lil easier and faster. Except: wheels with hubs and tires I'm thinkin about to change the bearings in the BB. I have heared that it helps in cervelo bb's to get more smooth and stiff rotation and get more "confident".
1. Can anyone tell what which exactly bearings goes to BB86 pressfit as default (OD=30 mm Non-drive and OD=28 mm drive side)? Which bearings are the best for rolling resistance (RR) and durability in this case?
2. Is there somewhere rolling resistance test comparison for hybrid bearings vs sealed machine bearings? I've heared that hybrid brg's characteristics are sloping a lot after some mileage?
3. I've swap seat to ISM, armrests to PDesign and pedals to Favero. I thinking about to change chainrings to 54 or even 55 or oval. Can anyone reccomend any other changes in fuji bike?
