Did the same on Saturday - replaced the jockey wheels on my MTB - the lower one was almost completely round. Hardly surprising that shifting performance was sub-par.Changed the jockey wheels after noticing some unusual noises and behaviour. Definitely some wear in the bearing.

Playing with the stem lengths ?I have been there done that too. In fact I have had more changes of stem length on my bikes than I have had hot dinners or so it might seem ! You will discover on the next ride when you get the sore neck or back.Washed the bike. I thought mudguards were supposed to stop crap forming all over the bike? Pah!
Washed the dog. She stank.
Took the vacuum cleaners to bits to clean them - filters etc.
Replaced the crappy guy lines on the new tent with the good ones from the old tent.
Put the slightly longer stem back on the bike...I'll discover next ride why I didn't like it in the first place...![]()
outside, thermometer might say 6 but with no sun and a cold breeze the road bike got a quick wipe and the still non ebiked hybrid pieces of cut inner tube glued where the motor clamps on to hopefully stop any creaks once it's refitted. The part I think the motor needs has arrived but missing a couple of bits so awaiting the arrival of those....Also an attempt to cure a squealing front disc on another bike by cleaning the rotor with Fenwicks degreaser/cleaner, sanding the pads and adding a touck of Copaslip to the back of the pads when putting them back. Still need to test ride to check whether it's worked.
Well I did buy a new disc & pads, fitted them and guess what - more squealing and it seemed to get worse as they got more bedded in. Having tried everything to sort this out including undoing and retightening everything at the front end with no result, the only thing left was the brake mounting. So today I took off the 180mm disk fitted as standard (probably a bit of overkill to be honest) and replaced it with a 160mm disk and refitted the caliper without the spacer mount.The rotor cleaning & pad sanding didn't work and it still squeals like a banshee even with a light touch of the brakes, so I dropped the wheel out and swapped the pads round left to right this morning, but no test ride due to yet more rain. I may end up having to buy a new disc & pads as a last resort.
you may have changed its resonant frequency (ever run a wet finger round the rim of a brandy glass to make it sing?) by reducing disc size .Just an idea but for whatever reason no squeal is better for efficiency and street credSo today I took off the 180mm disk fitted as standard and replaced it with a 160mm disk
