The Paul Component Engineering Disk RHUB 170 is designed for symmetrical fat-bikes with 170mm rear axle spacing. Made right here in the good ol’ US of A in Chico, California.
If you’ve been around mountain biking for any amount of time it is likely that you are familiar with Paul Price’s Paul Component Engineering and the sweet parts they’ve been making since 1989. As with all Paul parts this hub is a thing of beauty. Precision and attention to detail are immediately evident.
Paul chose to partner with Industry Nine, a North Carolina-based US maker of high-end hubs, for their freehub and we think that was a smart move. The Industry Nine free hub uses a unique 6-pawl engagement mechanism with a 60-tooth ratchet. By using a “phased system” 3 of the pawls are engaged at any given time resulting in 120 points of engagement just 3-degrees apart. For comparison, most standard free hubs have about a 20-degree engagement range. Instant power is what we are talking about here!
The freehub body is compatible with 10-speed cassettes from Shimano and SRAM as well as 8 and 9-speed cassettes common on fat-bike drivetrains. In addition, the disk mount is the ISO 6-bolt standard.
There are 4 bearings in the Paul RHUB, 3 sealed bearings for the Q/R axle and a 40mm bearing supporting the freehub.
The included instructions have information about Specifications and Adjustment as well as detailed Servicing of the Industry Nine freehub including conversion to a 3 pawl system that reduces noise and drag but changes the rotation before engagement to 6-degrees instead of the standard 3-degrees.
These build up great using a Northpaw-S 47mm symmetrical rim and Sapim CX-Ray spokes!
