Bitex BX 211 Front ISO 6 Bolt Disc Hub
The Bitex BX 211 is the six-bolt disc sibling of the BX 212, and for a lot of riders the BX 211 is the better buy: six-bolt rotors are cheaper and more widely available, and the flange itself is a robust mount that has been on mountain bikes for twenty-five years. Bitex makes the BX 211 in Taiwan, and Bitex builds hubs for half the wheel brands you know.
We use the Bitex BX 211 Front ISO 6 Bolt Disc Hub on budget-conscious gravel, cross-country and hardtail builds where the customer wants the money to go into the rim. The BX 211 has been a reliable hub for us, and it is one of the lightest six-bolt hubs at its price.
The Bitex BX 211 is sold here only inside a wheel we build. Choose the rim, spokes and nipples in the configurator and the finished BX 211 wheel ships from Georgia laced, tensioned and trued.
Design and construction
The BX 211 hubshell is machined from aluminum bar with J-bend flanges and an ISO six-bolt rotor mount. Bearings are sealed cartridge units in common sizes, so replacement years down the line is a ten-minute job with a bearing press.
Bitex keeps the flange spacing wide for the rotor side, which is what gives a BX 211 wheel its lateral stiffness.
This is the front hub, and a front hub has no freehub. What matters here is the part of the hub that carries the wheel: the bearings, the seals, the axle and the two flanges, and the front BX 211 shares all of them with its rear partner. It is the simpler half of the pair and the one that runs longest between services. The driver and engagement story belongs on the rear hub's page; this page is about a front wheel that spins freely, stays sealed and builds stiff.
How it rides
The BX 211 is not a downhill or e-bike hub, and heavy riders on rough terrain should look at a stouter option. For road disc, gravel, cross-country and everyday trail riding the Bitex BX 211 is excellent value.
A front wheel is where you feel a hub least and a build most. With no drive torque to carry, the front BX 211 can be laced two-cross or even radial on the non-rotor side on a rim-brake bike, which makes a lighter, more direct-feeling wheel; on a disc bike we lace both sides crossed so the rotor's braking torque has spokes to pull against. Either way the front wheel is the one that steers, and a stiff, true front wheel is most of what makes a bike feel precise.

This version
This version is the 6-bolt hub in Thru Axle 15x110mm Boost, Thru Axle 15x110mm Boost RockShox Torque, drilled for 24h, 28h, 32h, about 140g, in black, red. Those are the only things that differ between the versions of the BX 211; the shell, bearings and seals are the same.
Six-bolt is the original disc mount and still the most universal: any ISO 6-bolt rotor from any brand bolts straight on, rotors are cheap and easy to find anywhere, and the six-bolt flange is a robust, simple interface that has been on mountain bikes for twenty-five years. Centerlock rotors do not fit it.
Sizes, fit and compatibility
The BX 211 takes J-bend spokes in any gauge; Sapim Race or Competition with brass nipples is our usual recommendation on a BX 211.
Good rim matches for the Bitex BX 211: Stan's Crest and Arch, WTB KOM Tough, DT Swiss M 462 and XM 421, Velocity Blunt, KinLin TL, Race Face AR.

The figures, certificates and media above are Bitex's own. ProWheelBuilder does not run these tests; our part is the wheel we build on the hub.
Building it at ProWheelBuilder
Bitex makes the BX 211; ProWheelBuilder is an independent custom wheel builder in Georgia, not the manufacturer. Spokes are cut from the ERD we measure on the actual rim, the wheel comes up in stages on a tensiometer, and it is stress-relieved and trued before it goes in the box; tape and a valve go on if you ask.
In the configurator only rims and spokes that fit the drilling appear, combinations that are not made are struck through, and the price updates live.
Warranty
Manufacturer's warranty. Bitex warrants this product against defects in materials and workmanship. The duration, conditions and claim process are set by Bitex and can change without notice, so ask us and we will confirm the current terms before you buy.
ProWheelBuilder. Lace this into a wheel here and the finished wheel gets our own one-year warranty as well as the maker's. For twelve months we replace broken spokes however they broke, and the work on the wheel is on us - truing, re-tensioning, a rebuild where it is needed. If the rim or hub is covered by its manufacturer we put the claim in and chase it; if it is not, we supply an eligible replacement rim or hub at 25% off the current retail price. Carriage both ways is the customer's, and this does not cover wheels built from parts you send in.
Full terms are on our Policies & Warranty page.
BX 211 Front ISO 6 Bolt Disc Hub questions
Will my rotors fit this hub?
This is the 6-bolt version: any ISO 6-bolt rotor bolts straight on with six T25 bolts, which is still the most common and the easiest rotor to replace anywhere. Centerlock rotors do not fit it - for those, take the centerlock version of the same hub, listed separately.
Six-bolt or centerlock?
Six-bolt rotors are cheaper and universal; centerlock is lighter and quicker to swap. The BX 211 is six-bolt; the Bitex BX 212 is the centerlock version of the same hub.
Can I convert the BX 211 axle later?
Yes, with Bitex end caps. Tell us your frame's standard and we fit the right caps before the wheel ships.
Is ProWheelBuilder the manufacturer of the Bitex BX 211 Front ISO 6 Bolt Disc Hub?
No. Bitex makes the hub. ProWheelBuilder is an independent custom wheel builder in Georgia that builds it into a finished wheel to your spec.
Does it need special spokes?
No. It takes standard J-bend spokes, which the configurator offers in every gauge and finish we stock.
How long will the wheel take?
Build time comes down to parts availability rather than bench time. The estimated ship date is shown in the configurator before you check out.
