Wolf Tooth comes to the rescue of non-boost wheel owners

Boostinator saves high-end hubs from oblivion

If you’ve been reluctant to upgrade to a new mountain frame or fork because you’ve already invested in a high-end, non-boost wheelset, Wolf Tooth might have the solution to your worries about the cycling industry’s nefarious attempts at planned obsolescence.


Wolf Tooth’s new Boostinator kit allows you to use your non-boost wheels with boosted frames and forks. Specifically, it changes the front axle spacing from 100mm to 110mm, and the rear axle spacing from 142mm to 148mm. 

The front hub kit consist of a longer axle endcap:

Boostinator front hub kits consist of an precision-machined elongated end cap, while the rear axle kits consist of an end cap, rotor spacer and longer bolts. Pricing for the kits range from $25 to $39. (UK and Australian pricing was not available.)

The rear hub kit consist on a rotor spacer, longer endcap and longer rotor bolts:

Hubs supported

DT Swiss

Wolf Tooth makes front and rear kits for DT Swiss 240 and 350 hubsets.

Additionally, Boostinator end caps are also compatible with some wheelsets made by Roval/Specialized, Giant, Syncros and others that employ DT Swiss internals. Owners should contact Wolf Tooth with specific compatibility questions.


Riders with Hope hubs are also in luck, so long as they have the EVO Pro 2 model.

White Industries

The Boostinator is compatible with MI6 hubs.

Industry Nine

Wolf Tooth supports Industry Nine Torch wheels, but not those that use a 2:1 radial lacing.

Boostinator considerations

Wolf Tooth notes that front and rear wheels will need to be redished to center after installing the Boostinator kit. Additionally, these kits are not approved for use with rotors larger than 183mm.
