    Identifying the pivot point is easy - look at where the big pivot holding the swingarm is. This only works with a single pivot, so there's no trying to work out where the instant centre or centre of curvature is. I've done this to 3 frames - Scott Gambler, Scott Voltage and Evil Undead, and I...

    Well I'm not just running tensioners; the DMR Bolt and Black Market Killswitch have concentric BB pivots which means there's no chain growth and therefore have horizontal dropouts so no tensioner required. With the Evil Undead and Scott Voltage I made a jackshaft, which put the chain around the...
