In reply to 9Tom Ripley:
> Old mountain bike inner tubes...?
Spirally cut the MTB inner into 1" wide tape ( a lot easier than it sounds) and wrap the shaft like a bike handlebar. No glue needed, the ends can be stretched and tucked under. You can add a simple 3/4" loop cut from the tube for extra security if you want.
I use it on my Apexes. 3 seasons (well, 2 and a half...)so far and no loosening. Gives an excellent wet grip and really reduces heat loss. Easy, cheap and warm. Just ask a bike shop for old inners from their bin if you don't have any.
