Shimano Ultegra Calipers on Audax Mk 3......

[Planet X]

Hi,
Can someone please clarify just what I'm looking for here please. I see two options on "Bike Discount.de",
 https://www.bike-discount.de/en/shimano-ultegra-br-r8100-brake-caliper-set
or
https://www.bike-discount.de/en/shimano-ultegra-br-r8110-direct-mount-brake-caliper-set-1

basically, the r8100 or r8110's?
Just a tad unsure what to order.
Cheers.

I don't think you want either.  You definitely don't want direct mount, that requires a frame and fork with specific fittings, rather than the generic hole for a central bolt.  I'm also almost certain you need a deep drop brake for the Audax frame, something like the Shimano 451, but you'll need someone with that model, or a phone call to SJS to confirm that.

Thanks for the reply PH, actually, I’m going to measure from crown bolt to mid rim and get an idea, as recommended.

Current brakes, Shimano R451, dual Caliper, deep drop. Mechanic told me they’re fine, in good nic and no need to upgrade……..except, 😀, I’ll fit good quality pads instead, most likely SwissStop.
Ultegra will not fit. Money saved.
