So I've been breaking rear rims a lot lately, and on particularly harsh hits. I've never really had an issue with breaking rims other than the occasional dent, but in the last month I've gone through 3, and on trails im very familiar with and never had issues before.
The one consistent thing seems to be that its on smaller maybe baseball size rocks, twice with a bit of a hole before it to make that square edge even worse and pretty sharp/square edge and on decently quick sections of trail. I think i had been on the brakes at least a little each time. But i've hit those same rocks for years and never had an issue, if anything my rims are stronger, and im running 23.5-24 psi, with inserts, once without inserts. none of these have damaged the tire at all, no evidence of the the tire bottoming on the rim, or the rim impacting the rock.
its hard to feel exactly what went on each time, because its been so sudden, but i hear a bit of a bang, the type you hear when your wheel imacts something somewhat hard, but not the twangy harsh sound/feeling when you hit a rim, or REALLY smack your rear tire. I feel it, but it doesnt feel like a huge impact, though there does seem to be a lack of movement from the rear end at the same time. hard to tell if im feeling the rim crack, or if the shock is actually bottoming, or maybe the linkage is hanging up somehow. These do not seem like situations where i should be bottoming.
My thoughts are maybe on the super high speed end of the spectrum of HSC movements, its not open enough. Or on those super high speed shock movements, its too open and blowing through all the travel to bottom.
to me it feels like if anything my HSC could be more open, like its not quite active enough on those really quick impacts, especially when they're repeated. though i can see how it being too open could cause the same feeling if its bottoming my shock too easily. its on such quick impacts that are over with so fast its hard to feel it very well.
Shock is an EXT Storia.
Any ideas?
