Advice on 7 speed rear mech please!!

RichC-TRI

Dear all,

I'm running an old beloved 7 speed (dont laugh - I love my Claud Butler frame geometry!) race bike as my commuting bike. My old Sora deraillier is about to give up the ghost. Do you know if the current Shimano Tiagra long rear mech is compatable with 7 speed since all modern gear shifters are 8-10 now.

If not can you recommend a suitable piece of kit that is 7 speed suitable.?

if you have shimano shifter then any shimano mech will do fine.

Rich, try asking in the commuting workshop section, I think the gearheads have all started posting there now.

My old bike has a tiagra but I'm afraid I havent a clue (not too clued up on gears) :oops:

While we are on the subject - is the pull ration of Shimano mtb drivetrains the same as road?

My commuter's rear mech is on its way out (spewing brown grease and loose at the hanger) and I'm thinking of a mtb component in the hope that it will be more robust for the winter.
