Changing gear during heavy rain

[DGR]

During heavy rain, instead of turning my twist-shifter, my fingers can just slip over it, even if I tighten my grip.  So it’s difficult (or impossible)  to change gear.  I assume that a film of water gets between my fingers and the twist-shifter, and acts as an unwelcome lubricant.

I’d be grateful for any advice that anyone can provide about anything I can do to ensure that I’ll be able to change gear reliably even during heavy rain.

Would wrapping an elastic band (a big one) around the grip a few times give a softer rubber surface to hold?

BTW there are at least 2 different Rohloff grips - maybe one is better than the other when wet?

Wrap a strip of double sided Velcro around the grip and lock it onto itself.

I like the triangular grip, in part because summer and winter I cycle with thin leather dress gloves, which can get slippery when wet.

Before I changed to the Rohloff and its original triangular grip, I used yellow knitted glassfibre workmen's gloves which came with little black spots of some rubbery, grippy stuff on the palms. I bought them at the local hunting, shooting and fishing store. Bit hot in summer but I live in Ireland where the rain didn't get the memo about taking a break in the summer...

I almost always am wearing bike gloves, they help get grip on the shifter.

I am in USA.  There is a product here called Shoe Goo that is similar to a glue, comes in a tube like tooth paste.  You can put some of that on a shoe sole to build up the sole where it wears down.

I put three beads of Shoe Goo on my shifter, mine is the second generation of shifter, round in shape.  I wanted to make it more triangular in shape.  I applied two or three layers of Shoo Goo, it shrinks as it hardens.

Photos attached.  Photos are nine years old, I am still using it the same way as shown in the photos.

I do not know if a similar product to Shoe Goo is made where you are or not.

I use the pimple gloves that are made for horse riders if it's cold and wet
.
I've also found I can slide a soft handle bar grip down over the twister. Once on I cut it to the correct length. The added diameter and rougher surface help to give me a better grip. Once it gets worn very smooth so my grip suffers, I can cut it off and replace it.

I never cycle without gloves or mitts, the only gloves that haven't been easy to shift while wearing have been the Buffalo Mitts and the Spada over gloves.  But those are rarely worn and so good in the circumstances that need them, that I'll put up with it.  I just think ahead, leave a bit more time for the shift and make sure I have the best possible grip before shifting.
