I've got a Scott speedster hybrid and the crank is loose ( rocking side to side ) it's only done about 30 miles does any one know how I tighten it up also do I need any certain tools to do this thanks sinon
Chances are the crank arm is now damaged and will refuse to stay tight. I am guessing this is the left/non-drive side crank (it nearly always is). If the bike is new and has only covered 30 miles then it should be returned to the supplier for a new crank arm or chainset to be fitted as the bolt/nut that secures the crank has not been checked during the PDI.
ok home now and had another look i removed the allen bolt from the crank none drive side to see whats what and have now orderd a puller and also the other part to try and tighten or remove and inspect it.... thanks again for your help
Well one very happy chap here my mate popped over and he lent me the tools I needed to sort this so I took the crank right off and the bearings right out all ok so I greased them up and put it all back together and all is just fantastic.
Thanks again all for your priceless help
