Product info
About This Product
Let us guess, you've just got home from the nationals and you left your drop-out adapters behind while packing your bike to fly home? All good, we've got you covered. Dropout packs are sold separately in Pro 10mm, 15mm, and 20mm. Please note, there is a slight tolerance difference between the Velox & M2 frames, so if you have an Velox, we do not suggest purchasing the M2 adapters as they will bottom out against one another before the wheel is secured in the dropout.
