T34C - There's an alternative to leather wraps. It's called ColorWheelz, and it is a vinyl coating that comes in different colors and textures. I've used it sailing in freezing, blustery conditions on Lake Superior, and the metal
wheel was comfortable to use bare handed. In a nut shell, you pack your
wheel between two flat pieces of cardboard, ship it to them, and they fully immerse and heat shrink the vinyl to your
wheel in the color/texture you want. They then cut the vinyl up the spokes to within however many inches of the
wheel you want, and ship it back to you in about a week. It's very cool stuff. Though I only experienced it in cold conditions, they say it works equally as well in hot temps, as the metal is always insulated from extreme temps. And it doesn't absorb moisture, so the
wheel remains dryer in wet conditions.

I have a short "I Found it at the Boat Show" video of the product on our web site if you want to see more. It's under "Product Demos".
