I keep reading that lowers servicing is a doddle but never got around to doing it for myself because I've never clocked where to get the right oil from and by the time I've bothered to work out where I've lost interest.
Never seen it on CRC/wiggle etc – or is just a matter of wandering into Halfords and having a look around the motoring section for something with the right weight?
I have not bought a complete bike for 20yrs, built all my own wheels for the last 8, but for some reason suspension servicing has always alluded me.
edit – actually bothered to look properly and there are loads of options – looks like I can't put it off any longer.
