It utilizes the same locking zero frame contact ratchet arms to secure the front wheel of the bike by the tire, making it safe for carbon fiber frames. The tire trays work with tires up to 5” wide. Finally, with the optional Ramp & Bridge (sold separately), you can make loading heavy, larger bikes a breeze by simply rolling them up into place on the rack.
*Note that weight capacities of the rack vary when using the add-on. Acceptable weight configurations can be either:
60 lb per bike on innermost two bikes (Skaha 2 Plus), 30 lb per bike on outermost two bikes (Skaha 2 Plus 2 Add-On)
OR
45 lb per bike on all four bikes (Skaha 2 Plus, Skaha 2 Plus 2 Add-On)
