Hexlox suggest configurations

These are the Hexlox setups we use on bikes we sell and service. We no longer sell new Riese & Müller bikes, but we still service them, so the R&M setups are here for owners.

Tern GSD

Front wheel — not recommended, uses a cafe lock already. V1 GSD uses Q-LOC and V2 uses Universal fit — threaded 15mm front.
must be paired with a 6mm Hexlox bit
Rear wheel — not recommended, extremely hard to access and because the stock axle is much longer than normal, the Universal fit — threaded 12mm rear has a bad and scary tendency to unthread during use. This is a big safety concern and also is just unnecessary theft protection for a rear end that is already difficult to access by a trained mechanic, let alone a thief.

Saddle — sometimes needs to be paired with a magnetic bolt, depending on what comes from Tern’s factory
must be paired with a 5mm Hexlox bit
