Some Things About Our Steel

Fat Tires and Front Derailleurs
Earlier last year I was experimenting with wide rims + big tires on my Karate Monkey and had the joy of dealing with tire rub on my front derailleur cage. I was using an early proto of what led to…
Removing and applying decals on our frames
We do not apply a clear coat over our decals. Except for one brief period a long time ago, we never have. Yeah, your frame’s decals can get scuffed up. But we have never thought scuffed decals look bad. In…
Hub, Fork, and Disc Brake Compatibility
There are many 135mm-spaced hubs available these days, and until recently all hubs of this spacing were considered rear hubs. But 'fat bikes' have captured popular attention and more manufacturers are offering fat bike hub, fork, and frame options and…
Kickstands On Long Haul Truckers
Well for f*ck's sake. We thought publishing this piece would help pre-empt some of the emails we'd been getting about putting kickstands on Long Haul Truckers and others of our frames. What happened instead was that it brought a spate…
Getting The Most From Your Big Dummy
Geometry Chart | Installing Xtracycle Freeloader Bags (PDF) We’ve believed in the Xtracycle cargo bike system for quite a few years. We even thought about building ourselves custom complete long tail frames to house the Xtracycle modular components. So when…
The Environment

Bike Fit
Surly Bike Fit One of the most controversial and confusing aspects of cycling is bicycle fit and sizing. We here at Surly receive tons of e-mails and phone calls from folks all wanting to know the same thing: what size…
Fixxer
Judging by the regular flow of emails regarding our Fixxer, there seems to be some confusion about this item. Several folks have written and asked if this is what they need to convert their bike to single speed. Most of…
Pugsley
What Makes Pugsley So Weird? It all starts with the tires. Big, fat tires, particularly run at low pressure so they flatten out a bit, provide more ground contact and better traction than any standard tire. It allows the tires…

Single Speed Gearing 101

Spoke Calculation Info
These are the necessary Surly hub dimensions you'll need to help determine proper spoke lengths. Since we cannot do the calculations for you, we are not responsible for incorrect calculations. When in doubt, consult a professional bike mechanic. Please note,…
Caliper Brake Reach
The Pacer and Steamroller* frames use standard reach (47-57mm) calipers, although some short reach (40-50mm) calipers will work. We do not recommend the use of anything other than a good quality standard reach brake, including Sidepulls with 53-71mm or 61-78…
Bottom Bracket Sizing
What length bottom bracket (BB) spindle do we recommend for your new Surly? We don't. Spindle length is determined mainly by what the manufacturer of your crank recommends. If this information was not supplied with your crank, look it up…
Why Seatposts Slip

One-speed off-road drivetrain spew Despite the thorough instructions that are shipped with every Singleator, it has been called to our attention that not everyone understands exactly how to install one or what to do in the few instances that installation…
