Surly Big Dummy - Now available with Alfine or Nuvinci Internal Gear Hub!

In collaboration with Xtracycle in the USA (the longbike pioneers) Surly have created the Big Dummy.

Surly Big Dummy

The collaboration between Surly and Xtracycle means that most of the Xtracycle accessories are compatible with the Big Dummy frameset. Practical Cycles  have the range of accessories for the Xtracycle and Surly Big Dummy available to buy online.

Unlike the Xtracycle 'Freeradical' Kit, which converts a regular bicycle into the Xtracycle long bike, the Surly Big Dummy is a one-piece frame and fork set that is a ready made longbike frame (so no conversion is necessary).

This means a stronger and stiffer set up than the Xtracycle and thus a larger payload. So if you want to transport really heavy cargo the Surly Big Dummy may be the better option for you.

Practical Cycles can sell you a Surly Big Dummy frame and forkset for you to build yourself or we have our own specification of fully-built Big Dummy. We can also 'part build' your Big Dummy if you wish. We can supply and fit Bottom Bracket, Headset, and Seatpost if you wish. These are available on our Gears & Transmission shop page.

All Surly Big Dummy frames are supplied with a fully reamed and faced bottom bracket, reamed and faced head tube and fork crown race and all bosses for rack mounts mudguards etc tapped clean. This saves you a trip to your local bike shop and more importantly about £30 or more. All new frames should be prepared in this way before you fit bottom bracket, headset and other attachments - it ensures the longevity of the fitted parts. Disk brake mounts are not faced as, with the advent of adaptors being sold with most disk brakes, parallel fiting of pads next to rotor can be acheived by moving the adaptor.

Full bikes take 2-4 weeks build time depending on how busy the workshop is. Why so long you ask? We build it without rushing it which means you get a well-built bike with no corners cut. We hand-build your wheels and this takes time but rewards you with long-lasting wheels which will withstand the weight and wear. We grease all the right bits, tap, ream and face the various frame 'interfaces' and generally put a lot of care and attention into your bike.
