Gave the Stumpjumper a quick clean after yesterdays outing at Danbury
I whipped the driveside crank arm off too as it had come loose, inspected the splines which seemed fine and refitted it. I'll keep an eye on it and hope it doesnt loosen itself again.
Once I'd given it a quick once over and Mint was mud-free I noticed two things - the rear gear cable is irritatingly frayed and the drivetrain still had a large amount of danbury in it
Whilst there was nothing I could do about the gear cable (aside from ordering a new one, which I'll do later), I decided the drivetrain needed a proper clean so first out came the chain cleaner
I use Rhino Goo degreaser, its good stuff and supposedly environmetally friendly. Once I'd got the worst of it off the chain the rest came away fairly easily with a bit more degreaser. I even found a pair of jockey wheels in the rear mech, I thought they may have been lost forever
I rinsed it all off with the hose afterwards until it ran smoothly and all the grit was gone then left it to dry before lubing it up. Runs sweet now and seems to change gear better, weird that
