BlackburnTrainer and Trailer Axle Adapter

Adapt You Ride.

Blackburn's Trainer and Trailer Axle Adapter conversion kit replaces the original thru-axles on many disc brake bikes allowing you to use your bike on a trainer. This kit also allows you to install the Copilot trailer hitch on your thru-axle bike as well. Works on most bikes with 1.5 or 1.75mm thread pitches, and hub widths between 135-148mm.

Choose thread pitch 1.75mm for Rock Shox Maxle style thru-axles and the 1.5mm version for Shimano and DT Swiss E-Thru.

Works perfect

  • Familiarity: I've put it through the wringer

This adapter has been perfect!! I use this to pull a chariot brand trailer on a few different thrh axle bikes. What I love about it the mot is that 1 skewer is working for both thread pitches! I’ve used it on and off road and into rough single track — never let down. I also used it on my trainer over the winter.
