Rim Band Replacement- Which Way?

[pedronicman]

i have replaced the rim band a couple of times and sealed it differently each time, but it still goes down.tried using a bit of silicone but this still does not work any good suggestions?

See the rypusa website. There is a guy at the factory who does these in a matter of minutes every time, its down to technique unless there is something unusually wrong. new rim band and follow the technique should be ok

Ah... Rim Band's! Been there, Dabsters yer man!

I would suggest leaving the little "spacer" piece out that keeps you from squishing out the rim band.

I have used slime as lubricant, but mine is currently installed using the lubricant to install Tire ballz, without the little spacer piece and has held for several months.

Just be careful that you do not crank down on the nut when you install the valve stem.

For what it is worth, as others have said, it just get's easier the more you do it. I know I struggled and tried a million different things to get the dang things to go in place when starting to fool with them.

I spent a day in the Sherco world round pits and watched all the top guys do them and it is just a matter of technique and practice.

I clean everything up real well with brake cleaner and a wire brush and run a bead of silicone in both channels where the band sits.

I also silicone all around the valve.

If I had a new band and a new rim, I'd skip the silicone.

I use the spacer. I put the hole in the band over the hole in the rim, and everything is so slippery from the silicone that I just push on the valve stem and I can feel when the spacer pops through the hole in the band.

I think the 2 challenges are to squeeze out air bubbles, and not to pull the band near the valve so the hole becomes oval and pulls out from under the valve.

With a little practice, the whole thing takes 10 minutes.

Forget the silicone, clean the rim and band thoroughly, use plenty of tyre soap on both the rim and band and the band just pops in! Use silicone to seal the valve though. It's a doddle.

Put some grease in the groove where the rim tape sits, making sure it is completely covering the spoke nipples. The rim should be really clean,I use WD40 to do this.Only use as much grease to give a thin coating or you will have "bubbles" of grease stopping the tape seat properly.It is real easy as the grease lets the tape just slide in the groove,and if you get it wrong its easy to clean up and start again.This method has been 100% effective for me.
