Hill intervals today 9x4 minute efforts at 164bpm everything was going great untill i tryed to engage the 13 sprocket then all that i was experiencing was massive chain slip.
I was to annoyed to investigate there and then so took the lon route home at a good brisk pace to try and sort it out.
It turned out that i had completely buzzsawed my front chainring thats what happens when you ride nothing but the big chainring and change your chain but dont check your sprockets.
Buzzsawing is when a chainring loses its profile and each tooth ends up pointed (like a buzzsaws) thus making the chain jump.My fault lesson well and truely learnt!!
3+ hours tomorrow 130-140 with 5 minute massive gear efforts....cant wait!!
