Looking for a rim with a tubeless ready inner profile, that’s also rim brake compatible?  So were we!  Unfortunately it just isn’t an option in the world of rims, but we finally found a solution with the Sta-Tru Wheels TR21.  This double wall alloy rim has a 21mm tubeless ready inner profile with a CNC machined rim brake compatible sidewall.  The rim’s 22mm height and 25mm outer width makes for a really strong profile design, while the inner width works with a wide range of usable tire volumes.  Last but not least, the valve hole works with both schrader and presta valves.  If you have an old school MTB V-brake bike that you’re just not ready to part with, (completely understandable), or you’re just looking for a quantum upgrade for your original factory wheel set, this is it!

Since these rims are so versatile, we’re offering to build them up with a variety of hub options.

It’s true, not everyone out there gets to fly Airwolf, the Raddest 1980’s TV attack helicopter starring Jan-Michael VincentErnest Borgnine, and the guy with the eye patch?  Air wolf time!  Look at where they park the thing!   They sure don’t build ’em like they used to, (warning, seatbelt and sweet mag wheels may be required.  “Here we go”…”Woooo”).  What were we Muse-ing about?

Overall, these wheels represent a solid wheel set option, capable of fast, aggressive driving, I mean everyday riding, and will hold up to regular big city impacts.  The rims, hubs and spokes are all from quality manufacturers.  Here’s a pro tip, be sure to check out the sweet coupon codes here, and you will ultimately save money.  From start to finish, these wheels are built with quality components, and given the mileage you’ll get out of them, are an unbeatable deal.  We’re not joking around here.

Should you buy this wheel set?  Entirely your call.  Should you watch this short but sweet rock climbing video?  Absolutely.  One More Fun One.  Make That Two.

Thanks for watching.
