Loose Crank

[Ootini]

It was a SRAM powerglide 48/34, I don't seem to be able to find any details on the original SRAM unit, apart from a couple being sold for around £30 on ebay.

I think it was this : http://trekbicyclesoftucson.com/product/sram-s150-powerspline-compact-crankset-50-34-75615-1.htm But with a slightly smaller big ring.

Which has been replaced with this: http://www.chainreactioncycles.com/...gclid=COfgtYzH2L0CFe6WtAodmxEAgQ&gclsrc=aw.ds

Do they seem comparable?
