Trying to replace my 52/42/32 front 21 speed chainset with same. The outer chain ring 104bcd 52t would also be OK. Unable to find. This is for an English trike.

original Shimano

    I Googled outer chain ring 104bcd 52t and found a number of options. Oct 20 '20 at 2:00

    104 is MTB/Compact so 52 is a big ring for it. Might be better off replacing the crankset with a standard road triple, 52/42/30 is common.

  • I did the Google search too, and the first hits seem to be pages that list both 52t and 104bcd rings, but not a ring that has both. Specialites TA has rings up to 50t, and I don't know about other manufacturers that have even that.

  • Try to avoid linking to a reseller. OP is likely not in the UK, even though they've mentionsed an "english trike". A Manufacturer's website would be better, and OP can work to find it somewhere useful for them. // I see they are the manufacturer and seller as well, so fair enough.

  • Spa are good - they built me a wheel (that I later destroyed in a crash), but they only ship within the UK & Ireland at the moment
