This is for the Boost version. To run this version you need a Boost spaced MTB fork. Your standard gravel or cyclocross fork will NOT work with a Boost hub.

Pillar Wing 20 J-Bend spokes and alloy nipples are laced double-cross with 24 spoke front and 28 spoke rear. The ultra-light, yet durable, 370-gram rim (370 gram/29er; 340 gram/27.5) measures 26mm internal, featuring a 2.8mm offset rim bed for better tension balance and a more responsive wheel build.

These specs total up to a 1380-gram (1380 gram/29er, 1330 gram/27.5) wheelset that has a modern day wider rim design and can handle the rigors of cross country mountain bike riding.

For more extreme terrain, the 30mm Ridgeline Enduro wheels are a perfect pick.

Cross Country mountain bikers will lust after the nimble, yet durable wheelset. If your events have you looking for a weight advantage while still riding off the pavement, the Trailblazer is the option for you.

The rim is strong enough to be ridden on mountain bike trails, gravel roads, and for cyclocross. Due to the fact, however, that most current mountain bikes and gravel bikes having different dropout width standards, the Trailblazer wheels will be most often used as a mountain bike wheel with Boost spacing and a gravel or cyclocross wheel with standard 100mm front and 142mm rear spacing.

This page shows the Trailblazer in BOOST spacing, so this will be for MTB use!

Your mountain bike races are won on the uphills, not a timed segment downhill. Going lighter without sacrificing rim width and durability is key to better performance.  You are already gaining weight with a larger tire, offset that with a lighter wheel!
