I have candy 3’s on 1 of my bikes, liked them so much just bought a secondhand pair for my road bike.
The secondhand pair have been pretty abused and need a big overhaul however i picked them up cheap enought that i am not botherd. New chromo spindles can be got for £12-15 and the service kit including all bearings, spacers, seals and a drift for knocking out the needle bearing is only £12-14.
Having sripped the secondhand ones down it is not a difficult process and there are good ervice videos on youtube.
I have deceded to upgrade the spindles to some aftermarket titanium ones that were £40, granted a little spendy however one of the spindles needed replacing any way.
