tartan pixie Posted February 6, 2008 Report Share Posted February 6, 2008 Being a relic from back in the day i think of cranks as having a square taper and 5 bolt chainring mounts, the isis system seems nice and i understand the principle of bolting the cranks onto a splined axle but could someone please explain how the chainring and bash plate are fitted? Are these splined too and just slip on between the crank and bb or do they thread on to something? I've been looking at pics of chainrings on tarty and in the wiki but they've all got 5 bolt holes in them so i'm guessing i've missed something.

Jason222 Posted February 6, 2008 Report Share Posted February 6, 2008 A lot of the newer, smaller cog'd cranks have thread on cogs. The bash guard just slips on, then you screw on the cog onto the crank, and as you pedal...it tightens...to hell. Next to impossible to remove them.

Luke Rainbird Posted February 6, 2008 Report Share Posted February 6, 2008 Most mods, and newer stock setups, run this threaded crank system, but there are still some of the older breed of spidered cranks.Stuff like 'burns is pretty much spidered, though the bash fits onto a spline on the cranks, which has a lockring. The ISIS fitting is seperate from this, and on the crank, with the chainring mounting directly to the bashguard Quote Link to comment Share on other sites More sharing options...
