My tiagra 9 speed derailleur has gone bang (spring snapped).
1) can I fix it?
2) If not, I need to replace it. I need something that is 34.9mm band. All the tiagra ones I can find are 31mm band. I still have the band from the old one, will a new one screw onto that okay even if it is the one for the 31mm band?
If not, does anyone know anywhere that has a 9 speed triple derailleur in stock and can post it out today, 34.9mm band, triple, to suit 52 tooth front ring (ie not sora).
Or does anyone know if a 105 10 speed one will work?
cheers,
Joe
