Crowd sourcing for rear suspension setting suggestions for my 2018 Pivot Mach 429 Trail that I recently picked on clearance from Competitive Cyclist.
Our trails here in Michigan are quite flat and pedally with a lot of “chatter bump” type stretches of roots, rocks and braking bumps. So both low speed compression for pedaling efficiency and high speed compression for small bump sensitivity are very critical to good suspension performance. We don’t have the big hits and drops or extended climbs and descents like other parts of the country have.
The bike has a Fox Float Factory DPS Evol rear shock. I have played around with sag and settings on the shock quite a bit so far and I’ve been able to a find a combo of settings such that the low speed compression is okay but I can’t seem to get the high speed compression dialed in. When I set it up such that the small bump compliance is close to where I want it the rear end feels way to sloppy while pedaling and in g-out situations and when I set it up such that the rear end provides adequate support for pedaling and g-outs it comes at a significant cost to small bump compliance.
The best combo I’ve found so far is to set sag such that the O-ring indicator is at the blue “trail” line (30%) on the sag gage and run the shock in the “medium” position. These settings seem provide an adequate pedaling platform but as I mentioned above cause the small bump compliance to fall well short of my expectations.
Do you have any suggestions that may help me out?
