JUICE
MTB HARDTAIL - BOOST

SOMA - JUICE 29 TRAIL FRAME (BOOST 148) - DESERT METALLIC

The latest Juice 29er hardtail frame features practical updates to its feature set and geometry without diving too deep into progressive geometry. The seat tube angle is slightly steeper for easier climbing, but it isn't super slack and low. We wanted this to excel at flowy trails, singletrack, and long days in the saddle exploring or bike packing.

On this lively steel frame, you'll find lots of braze-ons and bosses for utility, sliding dropouts for versatility, and industry standards like 148mm Boost hub spacing and an English threaded bottom bracket shell.

A few words about sliding dropouts

We recommend positioning the sliding insert in the middle or front half of the slot. Sliding it all way back puts extra stress on the frame.

When setting up make sure sliders are evenly aligned. Wheel will be crooked if dropouts are not aligned. Loose bolts here can be hazardous to riding.

Make sure the bolts holding the sliders are safely tightened at all times. Those bolts should be tightened to about 25nM.

Inspect inserts and wheel periodically for correct alignment. Try carbon paste on the slider contact areas, if you are experiencing slipping even though the bolts are adequately torqued.

Don't forget to tighten the nut against the dropout after setting the limit screw.

Can I fit a rear rack?

Yes, you can. The Juice has braze-ons on the dropout and seatstay to fit a rack. You may need a rack that is "disc-specific" so the left strut can clear the disc brake caliper and cables. Axiom, Topeak and others make racks to fit with disc brakes. Also make sure your rack is tall enough to clear 29" tires before purchasing.
