Hi,

Can anybody advise if a 7/8 speed cassette will run on a quando hub currently running 6 speed?

The reason I ask is my Mrs brought a hybrid last year with 18speed gripshif. However she has issues shifting due to wrist injury. I want to convert it to Shimano STI (Alivio or similar) however I can only get these in 7 or 8 speed.

Advice greatly appreciated as I think 7 is the same spacing but 8 might be pushing it.

Thanks,

Phil
Cheers,

Phil

    is it a cassette or a spin on freewheel?

    The 7 or 8 speed shifter will work on the 6 speed 'gears' you'll just have 1 or 2 slots you can't use.

    6 speed is almost certainly a spin on freewheel, you'll need to measure the frame but usually a 7 will fit (8 speed freewheel's are available but rare).

    5,6,7 and 8 are all the same gear spacing and chain.

    Cheers guys,

    I thought that was case, I knew I could use the 7/8 speed shifters with the 6speed block/cassette
