Description
At I Know A Guy Bicycles, our “Trusted Partners” are more than just brands—they are vetted small businesses that represent the heart and soul of the cycling industry.
I choose to partner with people who take immense pride in their craftsmanship and who live by the same rule my dad taught me back in his shop: “If you can’t do it right, don’t do it at all.” In a world of mass-produced, “good enough” gear, these partners are true gems. They prioritize quality and longevity over quick sales, ensuring that when I recommend a product to you, it’s a product I’d trust on my own family’s bikes.
Trusted Partner: Bicycle Wheel Warehouse
Bicycle Wheel Warehouse is designed to offer a new dimension in the online market for enthusiast riders, aiming to meet cyclists’ need for high-quality wheels at affordable prices. We specialize in offering wheels that use component specifications that make sense, rather than wheels assembled from miscellaneous parts.
Our wheels differ from many other wheels available online. All of our wheels are 100% built in-house by hand, checked, and rechecked for proper spoke tension and wheel trueness. Compare our wheels with those offered by other websites that often purchase wheels and parts at close-out auctions from overseas factories and repackage them for sale in the U.S. as quality products.

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 make 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 Vincent, Ernest 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.
