ok.., i'm currently in the process of gathering parts to make this transformation. my plan is to change my sirrus to a time trial setup and upgrade the largest chainring from 48T to a 52T.
here is what I have thus far:
- Syntace C2 Aero Bar
- Nashbar TT Bullhorn Bar
- Cane Creek TT brake lever
- Shimano 8/9 Speed Bar End Shifters
- Profile Cork Tape
- FSA 8/9 speed 52T 110mm Chainring
now i'm not sure i can use my existing brake/ deraileurs cables, so here is my current spec of the sirrus. it's the entry level sirrus.
FRONT BRAKE: Forged 6061 alloy, 85mm linear pull, multi condition pad
REAR BRAKE: Forged 6061 alloy, 85mm linear pull, multi condition pad
BRAKE LEVERS: Shimano EF-35, EZ Fire, integrated with shift lever
FRONT DERAILLEUR: Shimano T-301, 31.8 clamp, bottom pull
REAR DERAILLEUR: Shimano Sora
SHIFT LEVERS: Shimano EF-35, EZ Fire
CASSETTE: Shimano HG-50, 8-speed, 12x25t
CHAIN: Shimano HG-53
CRANKSET: Specialized five arm, polished arms
CHAINRINGS: 48Sx38Sx28S, Super Shifter
BOTTOM BRACKET: TH Sport, square taper, 68mm shell, 113mm spindle, sealed cartridge
so, is there anything else i may be missing or may need? please advise if there are certain parts i can reuse from the original setup. also, how hard is it to tune the shifters so they will shift correctly? any pointers? i would love to learn how to do this myself, so if someone can shed some light, that would be wonderful!
