1UP Rack FAT & 29er Hybrid MTB Wheel Chock

Do you have a 1UP Rack and both FAT bikes and 29er MTB's and have the fat width conversion for the rack? Have you noticed the signature 1UP wobble when carrying your fat bike or 29er in those WIDE spools? This HYBRID wheel chock is the solution!

This FAT/29ER hybrid wheel chock accommodates both FAT 26/27.5 tires AND reg width 29er/27.5 up to 2.6" width. The center portion features a specially designed contour that locks-in on round XC and square DH/enduro/trail 29er MTB treads for excellent stability. The outer portion is contoured specifically for 26/27.5 fat tire profiles and features gripping lugs to locks onto the tread. Both profiles have a very low stack height for rock solid compression stability.

There are 2 versions of this model available as different print profiles:

1. Single piece, snap-on chock; NO hardware required! This version is a single piece chock that securely and firmly snaps onto the fat width spool. Choose this version if you don't want to bother with purchasing and installing hardware. Installation TIP: Press and snap on one side on at a time, then the other for easy installation. This chock clamps firmly around the spool for good retention.
2. 2-piece bolt on chock. This version is a chock with bolt on cap that requires m3 hardware to complete. Parts list below. This model is more freely rotating around the spool since the cap itself provides maximum retention.

The bolt on cap requires the below hardware to fasten:

• 4x, M3 heat set inserts
• 4x, M3 x 20mm stainless hex head screws
