DSS1 Performance Disc Road



The DSS1 is handcrafted performance steel at its finest. A few years ago we were ahead of the curve when we introduced disc brakes onto one of the Rapha Continental builds, and all that we’ve learnt from that project and the many disc road builds we’ve built since feeds into this. Built for the purpose of all day road riding, this bike is comfortable and forgiving but very importantly remains a lot of fun to ride. It’s quick yet stable, comfortable yet punchy, it will take the edge off that punishing climb and will blow your mind coming down… All the important factors that add up for an amazing ride.

The bike is disc equipped for comfortable all weather, all season braking and is built from oversized Reynolds 853 Pro Team tubing. Reynolds 853 Pro Team is Reynold’s highest quality, highest strength seamless air hardening steel, drawn to give an incredible ride while keeping minimal weight. Its heat treatment increases fatigue resistance, making it incredibly strong and impact resistant. We have custom selected the tube diameters, butt profiles and wall thicknesses to give the incredible ride of the DSS1.

The DSS1 is TIG welded and coupled with the excellent light weight and confidence inspiring ENVE Disc Road carbon fork. It is available in 54, 56 and 58cm sizes and includes a Chris King Inset 8 headset. There are options for Di2 cable routing and the frame will accept both cable and hydraulic discs.

Finished in deep granite grey with the striking pink to lime pearl fade it flies the ‘Signature Steel’ head badge, featuring the two Swallows, symbolic of speed and safe travel…

And here’s what the press have to say:

“Its got ample spring in its step and a level of comfort that will save you winces if you encounter, as I did, the occasional pothole disguised as a puddle.” Cyclist, Jan 2015

“Over several weeks of testing, with a handful of other highly desirable, top-end carbon bikes sat by its side in the garage, I found myself repeatedly picking the Donhou for a ride.” Cyclist, Jan 2015

“Donhou has sincerely delivered on the promise of something ‘for all roads, all day’. Its a charming bike” Cyclist, Jan 2015

“Fabulous bike with sparkling ride and handling” road.cc, Apr 2015

The DSS1 was selected as one of the RCUK 100 where they had this to say about it:

“Of course, there’s more to a bike than its paint job, but the deep granite grey with its pink to lime fade is gorgeous and utterly befitting of the craftmanship that has gone into the frame” RCUK 100 2014/2015
