Not of much use to most I suppose, but if anyone is looking for threw axle crash bungs (I've fitted on my ccm),here's a cheap trick.
Skateboard wheels x 4 (£4.19 off ebay)
8mm studding (£1.59 from B&Q)
10mm clear tubing (£1.89 a metre from B&Q)
nylon washers X4 (had them in the shed)
M8 nyloc nuts X4 (likewise also in the shed)
the 10mm clear tubing sheaths the studding to make it a tight push fit for the axle, so it's not floating.
rather than the £29.99 per set this works out at under £10.
Oh and if you want to make it sound better for some reason, call them A.D.R.D's (Abrasion Damage Reduction Device's......

)
Cheers Mark.
