I recently bought a shimano altus chain set from the retro mtb section and it has ended up going on my fathers bike. It is to replace his cheap shimano tourney FC-TX71 chain set. Got it fitted no problems, but when trying to set up the gears the dérailleur actually will not reach far enough to engage the outer ring.
So I figure a new BB will be needed with a shorter spindle. Is this correct or is there something I'm missing?
The tech docs for the old chainset can be found here
, and although I cannot find the tech docs, the replacement altus is a FC-MC16
Thanks in advance,
