Description

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 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!

The Speed Tuned ST280 hubs feature 72 points of engagement, (5 degrees) via a 6 pawl free hub.  The drive ring and pawls are super overbuilt in terms of diameter, (drive ring), height, (drive ring + pawls), and materials, (quality stainless).  Their bearing placement is proper, in terms of overall design meant to promote hub function and durability.

DT Swiss 350 hubs are excellent as well, they are finished to incredible standards, and include DT Swiss’ Star Ratchet engagement system, (same exact drive mechanism as with their DT 240’s and 180’s).  These hubs get the job done, hold up extremely well in an assortment of conditions, and have proven reliable even in the emerging context of high torque drive trains, (29er wheel bikes with 1×12 Eagle drive trains).  Essentially, DT 350’s offer you the option of buying one of the best performing hubs available anywhere, for only a modest price bump.  Given their huge value proposition, they are hands down a great option for any MTB rider that cares about their gear.

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.
