The Bontrager Strips and valves work perfect with the Velocity Blunt 29er rims. I mounted a Nevegal on the front tire without a problem and the mounted a Small Block 8 on the rear flawlessly. I ordered the parts on Trek Online. I used a mixture of Stans (70%) and auto Slime (30%). The setup has been great, going on my second month without a flat. Follow the directions here, but I would use a compressor to make things easier.

Ok, so I have been trying to use a floor pump all week to no avail. Finally took them to the LBS to use the compressor and it took thirty seconds. I am using Schwalbe rocket ron’s. They ended up being a superb fit with this setup. Once I finally got them out of the center channel the beads locked in and held air overnight with no sealant. I recommend not even trying this without a compressor though. Do the smart thing and hit up the LBS.

It’s all about PSI for that. Are you using a hand pump or a compressor? If you don’t have a compressor, use the gas stations (taking out the core of the stem) or at least a CO2 cartridge. In an extreme case, you can use a strap. Inflator straps fit around the circumference of the tire and have a friction lever or buckle that connects the ends of the strap.
Tightening the strap compresses the tire and forces the tire beads against the inside of the wheel rim. The strap is removed once the tire begins to fill with air.

How did avoid the tire sitting in the middle of the strip?

I have my tires mounted, soaped, patted and ready. However the bead seems to drop to the middle of the rim strip where it is recessed. I was able to seat one side by pressing it in with a lever, but can’t get the second side to seat without pulling it out of the first. How did you avoid this?

Sorry about that. However, I’m really not active on this site any more as other sites have taken up my time. I did do a post yesterday, but it is very rare that I add anything.

With that said, I did just add the feed to my Google Reader, through another account just fine. Try doing a search for the site within Google Reader and adding or if that is the method you used, try using the button at the top of the home page.

Thanks for the comment.

29er Velocity Blunts with Bonty Symtrical Strips all done with hand pump last night.
My only tip…follow the video exact, pat the tires all the way around to shape. Soap/water acts like a lubricant and temp sealant for the first seating. Once done, everything went very smooth.

“Watch the video, then rewatch…Pretty easy, take ur time, drink a cold beer.”

Great job on the video.

Just scored my Bonty rim Strips that were backordered will set up tonight on my Velocity Blunts.

Check the New Jersey Warehouse with your local Trek store….they had some in stock…

My local LBS said they were sold out (no more available from Trek). They wouldn’t be able to get a hold of any more until the 2011 line came out. Bummer. I just went to a fully rigid bike and I’ve had more flats this summer (regardless of air pressure) than ever before. I was hoping a tubeless set up would alleviate that. Thanks for the info. I may call them.

Interesting. I just checked my invoice from them, and it says:

2 406892 RIM TAPE BONTRAGER RIMSTRIP 29 RHYTHM

You may want to e-mail them the SKU# (406892) and see what they have as I couldn’t find that on their site anymore.

Good luck, and thanks for the comment.
