I own this bike from 2 years. It is very comfortable ,very Maneuvering bike especially for streets which are not very well-kept in good condition. Drives very well on flat with good speed (1 rotation in speed 9 or 10 is powerfull).
BUT i want to improve his climbing.So i intend to make it Dula Drive using Sturmey Archer CSRF3 rear hub to make the bike 3x9. But i prefer to make it 3x10 with speed 10-11-13-15-17-20-23-32 (or 34 ) tooth sprockets.If its possible. Any help is welcome because capreo cassette is compatible only with Capreo hub.So when i replace the hub with Sturmey Archer CSRF3 may be,i wont be able to use my capreo cassete and have to replace it with Shimano Tiagra HG500 10 Speed Road Cassette 11-32 or 11-34T If my chainweel is 45T which one will be ok? REAR DERAILLEUR is SHIMANO RD-F700SS CAPREO, 9 speed.All advises are welcome.
