In this blog we get to talk with Lael Wilcox, an ultra-endurance athlete who is known for winning the 2016 Trans Am race 4,200 miles long, and the Tour Divide 2,745 miles long. She also set the fastest known time in 2017 on the Baja Divide, a 1,700 mile route through Baja, California. ...
Asymmetric Bottom Brackets BB30A/PF30A
As if the current crop of bottom bracket standards weren’t confusing enough both shop mechanics and consumers now must contend with even muddier waters in the form of “Asymmetric” bottom bracket shells. Simply defined an asymmetric bottom bracket shell is not identical on both sides of the frame’s...
Anyone who's ever tried to press a standard screwdriver against a Phillip's head screw knows the importance of having the right tool for the job. With bicycles and components becoming more specialized all the time, having the proper tool at hand for a given repair has never been more important. Having the right tools helps in several ways...
What do I need, Over Axle or Open Bore Adapters?
This is a question we get a lot in our tech calls. And the short answer is it depends on the type of axle your hubs use: shouldered or non-shouldered. A non-shouldered axle is smooth across the length of the axle, allowing for it to slide completely thru the bearings. If you can remove the axle ...
Bearing Maintenance & Replacement
With Summer winding down and Fall right around the corner Cross Season is here! As tough as cross is on your body it can be even tougher on your bike and its components. Mud, rain, dust and snow can be brutal on some of your bike’s most vulnerable parts: bearings. While mileage affects bearing life, there...
T47 bottom brackets are fairly new to all of us. We discussed some of the finer details of T47 in this post. Two advantages of the T47 system are that it can be used across a large spectrum of frames and with almost any crankset. Wheels Manufacturing currently offers T47 cups with either inboard bearings or outboard bearings. Both types of cups ...

Think of T47 as a ...
A history lesson
To understand the differences between a standard mount derailleur (and hanger) and a direct mount, let's first review a few key features of what we now call a standard mount derailleur. We should all be familiar with how a rear derailleur attaches to the bike. Hopefully it uses a replaceable derailleur hanger, which has an M10x1...
Derailleur Hangers, nobody gives them a second thought until they break one. About the only thing that’s a bigger pain than breaking a hanger is trying to find a new one. Because of the large number of hangers out there, the chances of having one in stock are pretty slim and often times you may not be able to source one from the bike ...
In 2018, SRAM introduced mountain bike cranksets which use a new technology name DUB™ (Durable Unified Bottom Bracket). Meant to simplify frame BB and crankset compatibility across their product lines, it brought about yet another standard to understand. In 2019, SRAM began rolling out DUB cranksets on their road cranksets. Once the SRAM road...
