Customization

Can I Run an Internal (IGH) Gear Hub on your Frame?

It is possible to run an IGH in the Rhino with sliding dropouts. Rohloff

Can I Order a Custom Bike?

We’ve assembled our stock builds to provide you with the best mix of price and durability. In the case of small parts substitutions or, if you would like a completely custom build, please contact your local bike shop.

How Big of a Tire Can I Fit in Your Frame?

All of our frames can fit up to a 5” tire.

Do You Offer a Single Speed Version of Any of Your Frames?

The Rhino is offered as a complete bike built as a Single speed.

General

Can I use a dropper post?

Yes - the Skookum/Skookum FLT/Rhino FLT all have internal routing for a dropper post. The Rhino and Corvus have cable routing for externally routed dropper posts.

Can I Run A 27.5 + or a 29+ Wheel Set on My Fatback?

Yes, the majority of Fatbacks of yesteryear through today, and all the new models will accommodate a 27.5+ or a 29+ wheel set (with exceptions of course). The main exception is the fork, the Bluto is not recommended with 29+ tires but works great with the 27.5+. The bottom line if you’re using a Bluto, go 27.5+. Go 29+, if you’re running rigid (or want to purchase a 29+ specific suspension fork.

With older models: 190, 170, Steel, and Ti, you can run a 2X drivetrain with exceptions of the Ti slider and the Rocker frames in 16” or smaller with the Plus size wheels.

What is the Difference Between the Fatback Alaska Edition and Hadley Hubs?

Hadley makes hubs we consider them to be the finest hubs available in any width. They have proven themselves time and again under the most extreme conditions both hot and cold (Rating: Durability - 10, Weight - 8, Performance – 10, expense -10 (but worth every penny). Our Alaska Edition hubs have been the beneficiary of trickle down technology and have been getting better and better every season. For 2016 have made them smoother, lighter and stronger than ever before. (Rating: Durability - 8.5, Weight - 9, Performance – 9, Expense - 6 (worth buying a second set for a good friend).

Why run the 80mm rim width?

In our years of experience, 95% of the time, with the right air pressure you can ride the same snow with a 80mm rim as you can a 100mm rim. That other 5%, we don’t mind a little walking to warm up, and we are glad to save the pound of rim for that other 95% of the time that we are riding.

What can I do to “winterize” my bike?

Luckily, we do most of that for you (depending on the build). Most of our complete bikes come stock with carbon handlebars to reduce the transfer of cold to your hands, a saddle that stays flexible in extremely cold temperatures, and hub bearings that perform well down to -40. Many of our bikes come stock with Sram Gripshift, which has proven itself to perform better and is easier to use in lower temperatures.

Beyond that you can always do a little more: There are two parts to winterizing a hub.
The first and most important is the grease in the freehub body. The Alaska Edition hubs have slightly thicker grease in the freehub and we recommend replacing it with lighter oil if you’re riding in conditions below -15 Fahrenheit.


The second parts to winterizing a hub (other brands) are the main cartridge bearings. Other brands hubs may use grease that thickens in the colder temperatures and can be remedied with new bearings with a lower temperature grease.

What Assembly is Required with Complete Bikes?

Bikes purchased through a dealer will be completely assembled and ready to ride. If you don’t have a local shop that you can purchase through, the bike will be shipped in as small as a package as possible to reduce shipping charges, and will need to be professionally built. We recommend buying through a bike shop, and having them build it for you. If that is not possible, and you do not feel comfortable with the complete build of the bike yourself, please contact us.

What Kind of Brake Mounts Do Your Frames Have?

All frames are rear post mount 160.

With Tires So Large, Can You Feel a Difference in Frame Materials?

Simple answer: Yes, but not so much as you would riding a road bike. The biggest difference is with the weight and the responsiveness.

Shipping

Internation Shipping

We are more than happy to ship internationally, but please understand that it is not cheap. When shipping bikes, frames or wheels we must almost always use UPS or DHL. To ship a bike somewhere in Europe is often around $300 – $500 or more and then at least that much in taxes imposed by the country the bike is shipping to. Check your country’s import laws for more information. We try our best to get the biggest discounts possible for the customer, but it’s still an expensive proposition to ship outside of the US.  If you have a preferred carrier we don’t use or feel you can find better shipping rates elsewhere on your own, we encourage to make your own shipping arrangements. 

In the case of small items such as tires, crank sets, forks, etc., we can often ship those using US Postal, which is much cheaper.

How Much Does Shipping Usually Cost?

For a complete bike shipping is usually in the range of $100-$125, frames generally ship anywhere for $40 to $80. Prices are for the lower 48 states in the US.
