I have a early 90's Raleigh RT 500 42/53,13-14-15-16-17-19-21 cassette All components Shimano 105. I need to gear this bike down. It is just too hard for me to pedel.(It was Great 20 yr ago)/. Shifters on downtube now set on friction.
At first glance it looks like the easiest way to do this is replacing my 42/53 chainwheel with a compact 34/50t. I saw several affordable ones on Azon.xom like Shimano FC-2350 Crankset.I was planning on overhauling the BB anyway.
Anyone know if a compact crankset will bolt right up to my bike? Any barriers or cautionns up ahead? I read somewhere I might need spacers? between the compact sprockets.
Would a triple compact be even Possible?(without major changes)
