so I recently pulled the trigger on a 2nd hand Rune frame, even after reading all the neg comments on here regarding the bushings I thought it was worth a try. The frame is in really good shape but the bushings had been a little neglected so the rear end had a little movement side-to-side. The seller included a wear kit with the frame and some spare bushings.
So I removed the old bushing, most of which were worn out and installed new ones all round. The axles looked a bit worn so I installed the new keronite axles. All of them fitted fine (the seattube pivot axle was even a little loose in the new bushings. Normal?). But the main BB axle required a good bit of "persuasion" with the rubber mallet to go through. Once everything was in place the rear end had zero wiggle.
But squishing the rear end with no shock in place feels nasty. Whats happening is the main axle rotating a little because the axle's key has enough room to move within its hole in the frame. This small amount of movement becomes an inch or so at the rear wheel. Once the key can rotate no further in its hole the axle obviously stops rotating and the rear end feels pretty stiff. A noticable "thunk" can be felt through the frame.
So long-story-short = is this rotation of the axle/key normal? If there was less/no friction between axle and bushings would I not notice this thunk?
I hope that all makes sense! Any advice and similar experience much appreciated.
PS: the bike is looking awesome. Pics to come soon.
