Single Speed Spacing a Chris King ISO - what spacers fit?!

Recommended Posts

Hello trials hive mind!

Running full Shimano driver Chris King ISO rear hub and read in the interwebs, tested it at home - that most common spacer kits don't typically fit the driver..

Looking for some help if anyone has used any spacers to single speed one? I know TrialTech carbon ones fit (rocking horse poop), even considering getting a full cassette on it and just leaving it be..

TIA - Brett

Never had an issue with fitting single speed spacers to any of my king hubs…

Most SS spacers don’t have a spines anymore either. 

Not to teach you to suck eggs, but use the widest base sprocket you can as the alloy freehub on king hubs is soft, it will dig in. steel freehub/drive shells are hard to come by.
Torquingthe lock ring to 40nm should help reduce this.

Thank you for that Grant, attempted to pop a set I had lying around - think it's a Halo one, but just not having it. Have a wide sprocket that is a given as remember them being soft!

Will have a look and find something similar to the Superstar as they don't produce them anymore.

It's not just damage to the drive splines causing problems is it? I've had it before where the internal clearance on the spacers is minimal and a little filing of any burrs on the drive shell has made all the difference to getting them to fit.

A worthy point as well, the splines are worn but not horrific and I can get a splined single speed sprocket on it - just seems the diameter is out a mm or so for the spacers
