Re: the felt covers
The adhesive works pretty well, but I tend to do lot of climbing on the hoods so a few factors have come up:
-The initial cut shape needs to be perfect. If there's any overlap, the felt won't adhere to itself very well and eventually unravels. Also, if it is even a little bit stretched on the lever, over time it will come loose from all the minor twisting and fores that come from grip. It's also a matter of getting 3D curves doable with a 2D shape - this would have been a lot easier if I had a perfect 3D model of the SRAM lever body shape) - but anyway I'm really close now, on my 6th iteration of the shape.
-I'm looking into a few ideas of how to 'bind' the shape together around the lever body without adding much weight or effort, and making it as comfortable as possible. Judging by the reviews of Hudz hoods, people can be very picky about how the hood feels on the underside of the hood between the lever and the handlbar, so I'm trying to account for that as much as I can. By itself the felt is super comfy, but again it will eventually slip.
As for the finish? Felt is super comfy to start off with. Untreated it will last about 2-3 rides total, but looks pretty naff very quickly.
I can't say what I'm doing to the surface to make it work, but in a sense I'm making it tougher and harder (with no weight gain here), and the prototypes have held up for months, which is nice! The only thing keeping them from lasting all year long is the adhesive/shape/binding issue.
But, just for playing around or race day? Stretch it and mount it, you'll be fine and it works well. I'm just more interested in seeing if I can turn my efforts into a little product for sale to others... you know, to pay for my WW addiction.
