DT Swiss 54t ratchet upgrade kit - including springs and a virtually full tube of ‘special grease’. Probably enough to last a lifetime. 

Excellent condition - changed wheel set and back on the more basic 36t now. Gives a lovely buzzy noise.

Looking for £45 posted - bank transfer or PayPal if you cover fees.
