Bought a SNAP three weeks back. It arrived, got unpacked, then I fitted my Kona DEW+ to it, no problemo. Took about twenty minutes in all, start to finish. Next I tried to fit my half-century old Motobecane Grande Record with its 120OLD Campy Tipo hub & 5-speed freewheel.
No dice. The SNAP's axle-capture isn't long enough on the non-drive side to accommodate the 132.6mm overall length of the hub's hollow 10x1.0mm axle.
Buried in Wahoo's Support documentation there's mention made of an A&B adapter (that I apparently misunderstood should have been included with my SNAP) intended to overcome this kind of thing. Wahoo Support tells me these adapters are furnished with the higher priced wheelless trainers, not the SNAP.
Excerpted from an on-line Wahoo Support diagram.
Not exactly fully cognizant of the differences in models I bought a set of Wahoo adapters (yet unopened) that are for through-axle adaptation. Seems 12mm is a standard now as that's that these things are designed around, not the 10mm of my Campy hub.
If any forum members might have a wheel-less Wahoo trainer and don't need the A&B adapters that came with their device, let me know. I'd be willing to buy them off you if I can't somehow persuade Wahoo to sell me a pair.
I've made up adapters of similar nature before but lacking metal machinery and skills I've availed myself of the services of others to achieve this. In this case that seems unnecessary if I can source a pair of the Wahoo A&B adapters that someone else has but doesn't need
