Is it a setup issue, bad technique or inevitable that occasionally I throw the chain on my SS?
Previously I’ve thrown a 9spd chain off a trackend tensioned SS.
I then moved to a 1/8″ chain and it still happened, but less often.
Last night I threw a 9spd chain, surly singleator tensioned, off. Id have thought a tensioned chain – even a 9spd – would be less likely to come off.
Im a big lad, and quite strong on the SS at the moment. But I probably flop the bike over a little bit when honking – is that what’s causing the the chain to derail: twist/flex of the rear triangle plane?
This isnt a “clattering” derail on a bumpy descent either, its just a short sharp, steep honking climb.
On a similar thought, climbing a greasy 16% road climb, SS, with chunky Stouts on the back, I get a bit of tyre slippage. Especially if Im “dancing” on the pedals a la albert (it kind of un-weights the rear wheel a little bit on the start of the upstroke of the crank rev). Do road rider (especially featherweight ones) have traction problems on really steep climbs and naff-all rubber?
