But I think we're close to making it quiet. I've read it a few times on this forum, but this frame does have a lot of flex. Haven't had a chance to try it, but I can't handle creaking, Dropping the seat post down collar-to-collar must have dispersed the load of the post itself on the seat tube.įor testing, I made a 1.25" ID PVC collar so I can raise the post back up, but with this collar in place between the seat post clamp and the collar of the Reverb, which will hopefully disperse the load that the post puts on the frame. It was pretty amazing to ride a bike that was dead-quiet. I did a long climb the other day, stopped at one point and put my Reverb all the way to the collar and the seat-tube creaking went away entirely. This Rise has always been noisy since day 1 (creaks) and I actually only have about 300 miles on it to begin with.īut now that the linkage noise issue is resolved, that brought out my seat-tube-creak. I'll chime in with my results - I took the linkage apart (my axle was also installed with the threads facing the non-drive side), cleaned everything as usual, re-installed with LocTite 638. The Occam Blue Paper calls for Loctite 638 to be used. The Occam shares the same suspension design as the Rise. The Rise manual does not specify which cylindrical retaining compound to be used. The Rise Blue Paper calls for cylindrical retaining compound to be used on the upper pivot axle and linkage arm interface. However, Rises are coming from the factory with the threaded portion of the upper pivot axle facing to the left, non drive side. Also, the Rise Blue Paper manual calls for the threaded portion of the upper pivot axle to face to the right, drive side of the bike. This lack of retaining compound is causing the linkage arms to loosen up on the splined upper axle and thus rear frame play develops. However, Rises are coming from the factory without the cylindrical retaining compound having been applied. The Rise Blue Paper manual calls for a cylindrical retaining compound (Loctite 638) to be used on the splined interface between the upper pivot axle and linkage arms. While this does occur after a period of time, I've since come to the conclusion that in most instances, the creaking is the result of the linkage arms loosening up on the splined upper axle and play thus developing in the rear end. When I first wrote the post, I attributed the creaking to lack of grease. Please read the thread all the way through to page three. grinding and binding noises, you can "Short Cut" the upper and lower service procedures by just removing the axles themselves for lubrication. If you don't suspect pivot bearing failure, i.e. In the tech articles I go into full blown detail on how to clean, service and lubricate the entire upper and lower pivot assemblies. To avoid the creaking, I lubricate the axles about every three months.įor those interested, I wrote several tech articles on servicing the upper and lower pivot axles and linkage. Other than the occasional creaking, I've yet to have any major issues with the linkage and bearings. I now have about 2,000 miles on my Rise and know it fairly well. The lower pivot axle will sound similar to the upper, but will have a deeper tone to the creaking. When the upper pivot axle begins creaking, it will sound exactly like a creaking seat post or saddle rail clamps that are creaking. When this happens, the pivot axles will start creaking. Because there isn't any sealing, dust and water will eventually work into the pivot axle assembly and dry up or wash out the grease lubricating the axles where they ride on the bearings. The upper and lower pivot axles are not sealed.
