Tried to do the 30k run down into Ilans again missing the "over the mountain track" I mistakably tried last time. Climbing nicely out of Velendas, when spring in the rear mech gave out. 2mm Allen key usually releases a pin that allows it to come apart and re-tension on assembly but seemed to be blurred over from previous rock strikes so wouldn't undo! Jury rig of cable ties gave way as soon as I started riding again so removed chain and free wheeled down to the station where I was picked up by Steve. - third time lucky (if I can get the mech repaired???)
