<p><a href="https://surlybikes.com/blog/road_plus_brought_to_you_by_the_midnight_special">The Surly Midnight Special</a> uses open face dropouts which are compatible with both standard 12 mm thru-axles &amp;, with the use of <a href="https://surlybikes.com/parts/10_12_adapter_washers">their adapters</a>, 10 mm QR hubs.</p> <p>Although stepping the diameter up from 10 to 12 mm is trivial, you must also increase the Over-Locknut Distance OLD from 135 mm (very common OLD for road &amp; mountain wheels) to the newer 142 mm standard.</p> <p>These add the necessary 3.5 mm per side, giving a total addition of 7 mm + 135 mm = 142 mm.</p> <p>There may be some variation in the OLD, but a few mm shouldn't be too big of a deal.</p> <p>These adapter washers also provide a clearance fit for the M5 QR skewer to pass through. The OD is 19 mm, which I confirmed by measuring the locknut on 2-4 different thru-axle hubs I own. This OD is sufficiently small to allow the tool to install/remove cassette lockrings. The 19 mm OD also is likely to play a big role in locating the hub in many thru-axle dropouts.</p> <p>Good for emergency wheel replacements.</p> <p>Keep in mind you need to print a pair - one for each side.</p> <p><a href="https://surlybikes.com/parts/10_12_adapter_washers">Here are Surly's instructions</a>.</p> <p>These are untested. I don't anticipate ever testing them myself because I like thru-axles so much.</p> Category: Sport & Outdoors
