Groove between tire and rim - silicone or latex or ?
Moderator: robbosmans
Hey
I'm interested in filling the groove with something. What have you who have tried this used with good results? I'm thinking transparent and something that doesnt fall off from normal riding easy.
I hardly ever have any flats so for me if the stuff adheres well enough to stay there a few years the better.
Cheers! /a

Is the application for aero? Or what purpose does this serve?
you would think that the tire companies would have a rim lip to fill the gap...just like they make lips on car tires to prevent the rim touching the curb.
but i suppose all the rim lips are different in size and thickness.

What are you going to save? 1 watt? It sounds like a giant mess.
Mavic had/has such a product, called the aero "blade" albeit UCI banned its use.

As for using silicone or other to fill gap in search of aero savings, seems like a fools errand....no offense.

Thank you for all the replies.
I know it's not uci approved. Just about to build a nice deep wheelset and thought I shouldn't overlook such a simple mod to improving the shape.
I remember when doing tilework in the kithen/bathroom that some of these gap fillers are quite elastic and would probably do ok in moving with the tire/rim flex. Only the color might not fit hehe.

Well, I used some silicone to fill the gap, and that stuff is pretty durable. I was able to change tubes without it getting torn up but it was hard to seat it properly when inflating the tube again. It was a major pita to get it off the tire, so look at it as a permanent mod

Maybe a fools errand, but I recall seeing Contador's mechanic doing this in some of those TDF TT tech galleries from several years back. That was with tubulars of course.
The Mavic blade may be disallowed, but are you aware of anything specifically banning this silicone caulk strategy? I would think that, particularly on a tubular, it would be difficult for the UCI to determine if that it was simply an aero mod as it could also help tire retention, and prevent water getting into and weakening the tire/rim bond.
