I came upon a bike with the Fox F29 in 15mm form. This is Fox’s new change to their highly regarded F29 fork specifically built for 29ers. The 15mm is a design between Fox and Shimano designed to be stiffer than the normal quick release, but lighter than the 20mm thru axle. I got a couple of pictures of the F29 mounted on a bike and wanted to share them with you. The bike the Fox was mounted on will be discussed in more detail later this week.
Shimano XT 15mm hub
F29 with Fox’s proprietary 15mm thru axle
Comes with FIT Technology which to non-techies = RP23 for the fork
The bike was not available for demo so no thoughts on the fork. We do have leaked 2010 info on these forks here.
For us “non-non-techies”, what the heck does RP23 mean?!?
RP23 means “RL Policar” 23 is my age reversed.
Glad I could help.
RL
The RP23 is the very popular top of the line Fox Float shock. The Float lineup is usually used for XC/AM usage. I believe the acronym breakdown is:
R: rebound
P: propedal (sort of like a lockout)
2: engage propedal or leave it open
3: 3 settings of propedal (such as propedal really engaged, midly engages, barely engaged).
