SRAM S-900 direct mount brake — actual weights, prices, specs

S-900 brake spells end for mismatched builds

We’ve finally got a hold of SRAM’s S-900 direct mount rim brakes for an upcoming build.


We’ve measured the brakes on the BikeRadar scales of truth and the pictured example comes in at 152g including pads, which is actually 22g lighter than SRAM’s own quoted weight (though it’s possible this weight included some additional hardware).

Despite fluctuations in the wider cycling market, the original RRP of $125 / €130 / £116 per brake still stands true.

Fans of matchy-matchy bikes will rejoice at the news that SRAM has finally released a direct-mount brake — the memorably named S-900.  

The new brake looks very similar to SRAM’s regular calipers

The brake differs little visually from SRAM’s standard road calipers save for the loss of the rearmost stiffening plate and the mounting bolt.

The new S-900 brake has clearances for 28mm tyres, though looking at the images in the press release, we suspect you’ll be able to fit in something a little chunkier. The claimed weight is 326g per pair.

It has been a common sight to see SRAM sponsored teams building bikes with Shimano Dura-Ace direct-mount calipers over the last few as the new standard has gained traction; a practice that we’ve no doubt SRAM will be happy to see the back of. Katusha-Alpecin will be the first team to use the S-900 brake.

Expected to ship to the public in March, the SRAM S-900 brakes will retail at $125 / €130 / £116 each.


We’re big fans of direct mount brakes — they offer notably better power compared to a traditionally mounted brake, all while dropping some weight — and it’s great to see more options popping up on the market
