when I was a boy my father fitted plastic levers to my TY 175 due to constant breaking levers, now I'm older I run with cut down ones only big enough for a single finger. They suit me fine and don't have the childhood lever brakes. Not sure about rules on no bulb ends but cos I ain't no hand model it works for me.

Do you guys that use two or more fingers suffer from weak hands on a long trial?

I used to use Short levers on my Beta & were perfectly good & nice to use, Then decided to change to long levers & I prefer them so much more, just feels so much better & easier when using the levers.
