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.
The Mavic A319 is arguably Mavic’s strongest road/pavement rim.
Description:
The Mavic A319 is arguably Mavic’s strongest road/pavement rim. This feat is accomplished through the prodigious usage of aluminum alloy, a wide 24.5mm (x19.2mm tall) profile, and full double stainless steel spoke hole eyelets. This latter feature is a bit of a legacy tech, meant to help band-aid weaknesses typically associated with complex rim profile tolerances and difficulties associated with producing consistent quality metal alloys. But having said that, it’s a welcome feature that can only help improve durability. The double stainless eyelet also serves to act as a hardened bearing for which a softer alloy or brass nipple can rotate against, helping to build a better wheel. Last but not least, there’s this idea that the double eyelet serves to help absorb spoke vibration to a limited extent by acting as a dampener as it isolates the nipple from the rim material inside its chamber. Mavic employs this technology on some of their top end road rims.
Quick diatribe moment. The full double stainless eyelets are only offered on a few Mavic clincher road rims, the A319, the A719, and the Open Pro. Over the years on the internet we’ve read about Mavic Open Pro’s suffering rim cracking around the spoke holes. These occurrences seem to be met with a certain amount of enthusiastic naysayers about the Open Pro’s capability. For the record, we’ve been building with this rim for many years and we’ve built tons of Open Pro wheel sets, and haven’t experienced any rim cracking issues what-so-ever. If you over tension a wheel, rim cracking manifests regardless of rim strength. Every situation is different, but often we’ll see posted pictures of a wheel with five or six spoke holes with cracks. Funny how easy it is to assume the rim is bad, but yet the frequency of cracking, (several spoke holes simultaneously), rarely translates into some tough introspective questioning about the pertinent wheel builder’s skills, (or lack thereof).
End Diatribe.
You can’t go wrong with the A319. Due to its width it’s typically not suitable for full-blown, narrow carbon road race frames, but even this dynamic is changing as the industry is shifting to wider road rim designs. (Which used to be the Norm 15 – 30 years ago, what’s old is new again.) But aside from this one extreme, it’ll work well with just about everything else. In fact, they’ll work, and work, and work well for years to come.
