Great Fat Bike Roof Mounting Option

I've put it through the wringer

The details didn't call it out, but this is the 15x150mm version of the adapter. It installed quickly onto my Trio rack with just an allen key. The strap that is included for securing the rear wheel is kinda janky but considering this only cost $20 I couldn't be happier.

Expands options of Trio rack

I've used it several times

I bought the 9mm version for my Trio rack to use with my Pugsley, which has a 10x135mm QR fork. It installed easily and mated up with my fork just fine. Swapping this out for the 15mm adapter to use with my other bike takes about 2 minutes. I only gave it 4 stars because the strap that's included is just another regular-size strap. You can slip it into your existing strap and extend the length to fit around a fat tire, but the added hardware rubs either the tire or the rim. It's functional, but just seems like a shoddy compliment to an otherwise well-designed and well-built roof rack system. Simply providing a longer plastic strap would be a welcome improvement.


Hi what is the length of the 9mm one it does not have it listed. Would love to know ASAP.


There are two different answers regarding the front hub spacing? Which one is available currently? 142mm or 150mm?


Is this a 15mm x 142mm, or 15mm x 150mm?

Hey Brittany! The 15mm has a spacing of 150mm.

Hey Brittany we only have the 15 mm x 142 mm in stock right now.


will this adapter fit a borealis yampa?
