IB13: X-Fusion Sweep 650B Fork Joins the Family – Plus Updated Thru Axles & Remote Levers
X-Fusion’s big news was the very expensive Revel inverted crown fork, followed by their new dual crown DH fork and a prototype stealth dropper post. We covered all that right here.
But, hidden in plain sight was the all-new Sweep. It’s a dedicated 650B fork, designed specifically for the middle wheel size with specific offsets and axle-to-crown heights. Across the different wheel sizes, they standardized the trail ratio to keep the steering consistent regardless of size. The 26″ forks are 42mm offset, 27.5″ is 46mm and 29er is 51mm.
It’s also the first to show off their new thru axle, and there’s a new and much improved remote lockout lever that replaces the plasticky original. Pics and full fork specs below…
This, like many of their forks, offer internally adjusted travel in 20mm increments using a pin-and-ladder system, with 10mm fine tuning done with spacers. Check this post for internal pics and details to see how it’s done.
All forks with a quick release thru axle (generally up to 160mm travel) get a new proprietary thru axle. It uses a four pronged expansion piece that wedges against the inside of the dropout to keep it tight and prevent it from accidentally unthreading.
Lastly, there’s a new remote lever that controls the shock / fork lockout or travel adjust. It only does one at a time. It’s all metal and replaces the overly plastic model from before.
