Cycling Components That Don’t Quit—Because You Don’t Either
At Rotation Engineering, we build cycling components the motorsports way—no compromises, no shortcuts. With over 20 years of experience in NASCAR and 4×4 engineering, we apply racing-grade precision to the parts that matter most: bottom brackets, bearings, and drivetrain lubrication.
Precision-Machined. Rider-Tested. Race-Proven.
- Machined to tolerances of +/- 0.0001″
- Engineered for 10x the stress loads of standard cycling parts
- Sealing systems tested at 200mph
- Designed in-house in Ellington, CT
We ride, we test, we refine, so you can ride harder, longer, and with total confidence.
Lubricants Designed for the Extremes
Unlike large-scale manufacturers, we machine our bottom brackets and formulate our lubes for the toughest riding environments—from gritty gravel to the worst New England mud.
Because Every Pedal Stroke Should Count
- Enthusiasts who simply want the best
- Competitive racers chasing podiums
- Long-haul riders demanding longevity
Join a community of serious cyclists who refuse to settle.
I finally got to ride my hightower today, broke my foot in June and haven’t been allowed/able to ride it since. Your BB is the smoothest one I’ve ever ridden, and I had 3 Enduro XD-15 and Wheels Manufacturing BBs. Nice job!
I’ve worked with these BBs since the first prototypes: silky smooth and outlast the rest
Smoothest and most durable BB on the market…period.

About us
Long before our name was etched on a bottom bracket, we were building championship-grade components for motorsports.
Motorsports Precision, Applied to Cycling
We design, test, and refine our products to racing standards — ensuring that every watt of your effort translates to motion, not friction.
Cyclocross demands more from your equipment: instant power transfer, predictable handling, and absolute reliability in the worst conditions. The RaceLab 35 CX Tubular Wheels are purpose-built to meet those demands, drawing on Rotation Engineering’s motorsports-derived precision to deliver race-day confidence when the course gets ugly.
At the core is a 35mm tubular rim profile, optimized for the perfect balance of low weight, lateral stiffness, and compliance. The result is a wheelset that accelerates instantly out of corners, tracks confidently through off-camber sections, and maintains stability when conditions deteriorate into deep mud or frozen ruts.
To match your performance priorities, RaceLab 35 CX wheels are available with DT Swiss 240 or DT Swiss 350 hubs:
-
DT Swiss 240 for riders chasing every marginal gain with premium weight savings and elite-level engagement
-
DT Swiss 350 for bombproof reliability and race-proven durability without compromise
Both hub options deliver legendary DT Swiss performance, smooth engagement, and long-term serviceability, critical for a discipline where grit, moisture, and repeated pressure washing are part of the routine.
Every RaceLab wheelset reflects Rotation Engineering’s commitment to precision manufacturing and real-world testing. These are not just cyclocross wheels, they’re tools engineered to perform under race stress, lap after lap, season after season.

Check out the most common questions our customers asked. Still have questions ? Contact our customer support.
Where are your Bottom Bracket cups made?
Our Bottom Bracket cups are made right here in Connecticut using either aircraft-grade 7075 aluminum alloy or Grade 5 Ti-6Al-4V titanium.
Where is the anodizing done, and are custom colors available upon request?
Anodizing is done right here in Connecticut at one of our manufacturing partner’s locations, and yes custom colors are available upon email request (fee applies).
Why should I pay extra for ceramic hybrid bearings?
Ceramic hybrids roll faster, are more corrosion resistant, and pulverize small amounts of contaminants in the raceways.
Why choose titanium for a BSA cup over aluminum alloy?
Titanium is significantly stronger than aluminum alloy. BSA cups have limited material where the cup flange meets the threaded part of the Bottom Bracket cup, so material strength is key. Titanium offers more stiffness and resistance to misalignment than aluminum alloy. Titanium is also extremely corrosion resistant even without anodizing, and they look damn sexy, too.
What’s the deal with the hot dip chain wax?
Our proprietary wax hot melt is a custom mix of two different types of American-made Paraffin wax and three specific micro sizes of tungsten disulfide (WS2) dry lubricant particles. In crafting our wax hot melt, our goal was to save between 5-8 watts over traditional wet lubes, achieve better adherence, and offer better longevity and value than our competition.
What’s the deal with the polished bearings?
We offer polished bearings in both traditional and ceramic hybrid versions. Our proprietary isotropic polishing process first uses chemicals to soften high/rough areas in the bearing raceways left by machining and grinding. Next, the bearings are polished with ceramic media to remove the high spots. The process is repeated until the surface is super finished and micro-textured. The polishing process decreases rolling resistance and allows the lubricant to be better retained inside the raceways.
What brand of bearings do you use in your Bottom Brackets?
We start with the best Japanese bearings from NTN or NSK and upgrade their performance through an in-house service. We painstakingly remove the balls, cages, seals, and stock lubricant.
After disassembly and cleaning we inspect, re-assemble, and refill the
bearing with one of our application-specific greases. If selected during
checkout, we also can add ceramic balls and super finish the bearing
rings.
Does your hot melt wax lube contain PTFE or PFAS?
Heck no! PTFE is a frequently used long-chain polymer lubricant and also a very common dry additive in bicycle chain lubes. Fortunately PTFE is consistently outperformed in every applicable area for bicycle chain lubes by the much safer WS2.
The risk of PTFE being overheated
in a hot melt formula (changing it to a potentially dangerous short-chain polymer) and releasing PFAS emissions is too high for us to include it in our product.
Do you guys offer a hot melt waxed chain ready to install?
Yes! We offer 5 options:
- SRAM T-Type XX
- SRAM Eagle XX1
- SRAM Flat Top Red
- Shimano 12s XT-Ultegra
- Shimano 12s XTR-Dura Ace
How do you recommend melting the wax?
You should use only dedicated wax melters to melt your hot wax lube and always follow the manufacturer’s directions. We personally like the Silca wax melter but other paraffin wax melters are available online. Never heat our wax above 185° F (ideally 165-175° F). Never melt our wax near an open flame.
What Bottom Bracket standards do you make?
We currently make BSA MTN, BSA road, and t47 internal road. We also make spindle reducers for 24mm and 29mm spindles. Additionally, 30mm spindles fit directly in our Bottom Brackets without a reducer.
