I’ve got one of those NukeProof axles which I have used to swap my Hope Pro2 EVO wheels between my bikes (one QR one 12×135). The only problems with it are that the little sections on the end which fit in the dropouts are pretty small so it doesn’t look that secure (I’m sure it’s fine), and that it’s made of steel so weighs nearly half as much as the whole rear hub (200g).
To be honest I’ve never used it other than for popping a wheel in to check the set up or for storing a wheel in the frame. For riding I’d much rather take the cassette off and swap the proper end caps over rather than carry around that much excess weight… yes it’s weight weenie but 25g vs 200g… and considering the efforts we make elsewhere leaving that in there is a little daft.
My advise – buy the proper adapters and a chain whip and cassette remover.
Side note – 12×135 is fine with a Hope Pro2 EVO hub… but, if your hubs not EVO the axle may break (and I have read of EVO’s breaking but I’ve yet to do/see it myself and I broke many non EVO’s).
