A nice soft rubber for those scary tree roots too….. Are black chilly Trail Kings or Hans Damps too heavy?
I've been running a Hans Dampf up front for around 2 years now, first 26" and now 29", all year round, and can't see myself changing anytime soon. Trailstar compound, 2.35". It's a big old tire, but grips amazingly and when it does let go, it is still easy to slide. Can't say enough good things about this tire. Whether it's too much for the BCBR? Depends on what your aims are, flat out racing or fun!
Tried a Hans Dampf on the back (26") and it's a bit of an anchor, especially in the trailstar compound. On my 26" I ran a nobbly nic on the back which I really liked, but since moving to 29" have tried and ripped the sidewalls out of a Mountain king black chilli (good but lasted about 3 weeks) and a nobbly nic (good but lasted about a month). Currently on a ground control, 2bliss ready GRID, which I don't know if it is available in a 26", but it rolls quicker than the other two, and has just the right amount of grip for me, as I don't mind the back sliding around a bit.
If you're worried about the roots, stick a Hans Dampf up front but get something lighter/easy rolling for the back as the climbs will be painful otherwise.
