London Road brake caliper bolt size?

[scrw.]

Can anyone tell me what size bolt I need to mount some Shimano calipers to an LR frame please?

I'm pretty sure it's a hole for mudguards. The drop from hole to rim would be too big for any Shimano road rim brake calipers.

Perhaps the Tektro ultra long drop dual pivot brakes could be made to work, but why bother? It's a disc-brake frame. Get a second-hand PX Uncle John or similar and use cantis/mini-Vs if you prefer rim brakes.

No, I am building up a LR frameset and need to know the size of the bolts I need to mount hydraulic calipers to the frame. PX are not responding to my emails

I think post mount bolts are M6.

The bolts came with my disk brakes when I built my LR frame up, so I can't be sure but that seems about right.

Apologies.
