This might appear as a silly question - but in 40 years I have never used bar ends on any of my trial, trail or road bikes.
I understand that open ends can be a safety issue and as I would like to start competing I believe blocking the ends is a requirement. So I purchased some Hebo bar ends with the intention of fitting them to my TLR200 and Cota 247. However, I really don't have a clue what to do - do they go on the bars then place the grips on top of them or do they go on the outside of the grips ie: cut a hole in the grips....
One thing I do know is the Hebo units are too small for my bars although I can probably pad them with some old tube rubber.
