Disc lock size

[Bobz64]

Looking at a disc lock for a 2019 Gen 1 and there`s two size options available 10mm or 6mm pin, can anyone help me with hole size on the front discs please?

cheers

Most disc locks lock in the lattice mount of discs, and in the case of BMW - simply beyond the inner circumference of the disc.   Pin diameter is not important.

(Perhaps you are fitting a ‘Roadlock’ one to the brake caliper?  (I think that is the right make)

I’d recommend an alarmed disc-lock for two reasons.

1) you are not likely to ride off or move the bike after forgetting to remove it

2) They are pretty sensitive so shriek like crazy if anyone attempts to take an angle grinder to it.

I have an ABUS one (can’t remember model) but I think Oxford produce a pretty good one these days too.

I`ve had Oxford shackle type before but this has choice of pin sizes so I`m assuming it`s relevant to the hole size on the disc?

The difference is in the depth that the lock reaches.   

The one on the left - the pin goes on the inside of the disc where pin diameter is greater as it is possible to get a small grinder in to it.

The one on the right- the pin does go through the disc holes, so max diameter is important (but should fit)

Got an Oxford Quartz XA10 can attest to the shrieking like crazy, it's absolutely deafening, i keep it under my seat usually but recently haven't carried it, supposedly you need to charge it once every 3 months or after it activates once or twice but i had mine over a year now and only had to charge it once and even that was because i accidentally triggered it. Imo for daily use the built in alarm on the XR is more than adequate and far more sensitive than the disc lock. No way someone is moving the bike without it going off. So it makes no difference really if it's chained or not because I'll hear it. Despite this the disc lock is good to stop them still rolling away with it but that's all the security I need/use. XA10 can be had for about 40 quid, i think there are some newer versions available though.

Thanks for all the info guys. I`ve gone for a different model in the end

You should keep the model a secret.
