I have a 2013 Kona Raijin with sliders.
I have run 34 x 21 for the first couple of hundred miles that I rode in the fall when I bought it, developed a knee problem, and just changed gearing to 34 x 22.
I have a HBC Ti 34 chainring, brand new Niner ti cog, and a chain with the couple of hundred miles on it from previous gearing set up. Drivetrain wear should not be the problem. It is a King SS rear hub in excellent condition with recent shop re-build. Chain line is good and was set-up according to recommended method on this forum.
I have ridden the bike on the streets a bit over the winter, with some climbing, and no problems.
I had no problems before changing the cog, although as I said have only put a couple hundred miles on it.
Went to the local trails last week to give it a go, and soon after beginning the climbs, I heard / felt a big noise as if the chain might have snapped. Inspected on the trail, quick link (Wipperman) looks fine, etc. Ride more, problem occurs more frequently, definitely notice the chain has lost tension.
Take it all apart at home, re-set tension, clean sliders, bolts, etc, re-install, take out in the neighborhood and crank up a few hills with no problems.
Go to the trails yesterday, and soon after beginning my climb, it starts again. Big noise, big clunk, chain seems looser...
Definitely losing chain tension, which leads me to believe the sliders are moving, although everything is tight and clean with adjusting bolts in place and supposedly doing their job.
Any suggestions?
LBS says take sliders apart and hit them with carbon prep...
