Compatibility of your bike with the Old Man Mountain Racks

For full suspension bikes with disc brakes or v-brakes, for wheel size 26, 27.5, 29 and Fat Bikes, with QR skewer or 12x142/148 axles or een front QR15 acles.

With the entry on the market of bicycles with the new 12x142/148 axles it has become more difficult for you to know which Old Man Mountain rack is suitable for your bike. Axles have now different length and different thread pitches as there is no longer a standard.


Below we detail the compatibility of each of our racks with the different bike brands. The list is not 100% complete, as there are thousands of brands on the market. Old Man Mountain is able to fit a rack on almost any bike, but unfortunately there are a few bikes that are uncompatible. These will also be detailed below.

NOTE: In theory, all the brands and models detailed below are compatible with our racks. However, every bike manufacturer can suddenly change the configuration of their bikes, from one year to another or on certain models. Old Man Mountain has no way of knowing how each of the thousands of bike models on the market is configured. Nevertheless, for the moment the list below is accurate (and will be updated over time if necessary).




There are versions of Sherpa for 26-27.5-29 wheels, with QR skewers or 12x142/148 through-axles and for front QR15 axles by Fox and Rockshox. There are also solutions of Sherpa for Fat Bikes.



Almost all the versions of Sherpa are also available for the Pioneer.
