Hopefully I have done a physio out of a lot of money by buying a $10 pair of foam grips.
The standard items were, I think, causing "tennis elbow" - pain in the elbow region after long distances and tingles in two fingers of throttle hand.
A pair of foam grips, off with the bump knobs and a bar of soap and water and the foams slid on easy over the old grips.
Shouldn't be able to do that according to the guys in the bike shops but the foams expanded enough. Don't know how long they will last being stretched but better than a couple of hundred bucks and the exercises from a physio.
Did a run out through Tenterfield and further south with them on - feels weird because the grips are now twice the size they were - but no aches and pains in the arm.
FarRally this weekend should test the theory - still planning but to get the points up it means a between 1200 and 1600kms in just under 30 hours.
