Mountain

With the best mountain bikes from Rocky Mountain, KHS, Felt and Surly, Missoula Bike Source is Monta's mountain bike headquarters. 

Surly Krampus
$1,550.00
Surly's Krampus rolls fast, holds speed, and devours corners. Surly built its Boosted frame and fork out of tapered and butted chromoly and gave the frame a long top tube and short chainstays, so it's playful, smooth, versatile, and durable. The 29 x 3-inch Dirt Wizard tires on 40mm Alex rims take your trail ride to new heights of fun. These big tires offer increased traction, incredible float, and reduce the need for suspension because the large volume is plenty to smooth the trail. You'll also get a SRAM NX 1x drivetrain, Answer Pro Taper bars, and SRAM Level hydraulic brakes to make you the new master of terrain that used to be out of bounds.
Surly Pugsley
$1,900.00
The Surly Pugsley may be the original fat bike, but this one is far from the original. Previously a great all-around fat bike, the Pugsley has been redesigned to be an ideal off-road touring and exploration rig. Surly lengthened the chainstays 12mm for stability when loaded and so your heels float effortlessly past panniers. The tweaked rear rack mounts on the dropouts let you center your rack over the wheel, despite the offset rear triangle. Those dropouts will take a 142x12mm thru axle if that's your schtick, but this rig comes with a 135mm QR hub, snug as a bug with a pair of adapter washers. Pugsley brings back the 135mm-spaced offset fork, so you can run a front wheel with a spare cog or freewheel as a bail-out option to swap with the rear if your internally-geared hub freezes up in neutral or you smash your derailleur having too much fun. A plethora of three-pack mounts give you gear-hauling options aplenty, and a Surly Moloko Bar gives your hands damn near as many options as well, so they stay clappably happy even on your longest, story-generating adventures.
Surly Karate Monkey
$1,550.00
Years ago the Karate Monkey helped start the 29-inch wheel movement and, as time's gone by, many companies ­– Surly included – have experimented with even more wheel sizes. With so many different types and sizes of tires now on the market, riders have begun to understand the effect that tire width has on overall wheel diameter, and with ample tire clearance, you can see the benefits of multiple wheel sizes all on one bike. 27+ tires have the same rolling diameter as a 29-inch wheel, yet you get all the traction and floatation benefits of extra-wide knobbies. And that's just the tires. The Karate Monkey frame has recently gotten a makeover that includes the addition of features like internal dropper post routing, a new tubeset that uses the same trumpet tubes found on Surly's Instigator 2.0, and a slight tweak in geometry that is more progressive and trail-oriented. The Karate Monkey uses a horizontal dropout with a derailleur hanger that features Gnot-Boost spacing, which gives the rider the ability to run any kind of mountain bike hub they choose. 10 x 135mm QR, 12 x 142, or 12 x 148 Boost will all work in the Karate Monkey frame. The frame uses a 44mm headtube for broad fork compatibility and is ED coated for an added layer of internal protection. If, at any point, you decide you want to throw on some skinny meats, standard 29-inch wheels and tires can be swapped in with no issue. If you want to round-house kick some trail right in the face, the Karate Monkey is your sled. - 100% Surly 4130 chromoly steel frame and fork; double-butted main triangle and 44mm headtube - Adjustable rear dropouts with 145mm Gnot-Boost spacing. Works with 142, 148 12mm thru, as well as 135mm w/ 10/12 washer - Internal dropper seatpost routing with 30.9mm seat tube ID - Clearance for 29 x 2.55 or 27.5 x 3 tires

Surly ECR 29+
$1,900.00
The ECR is Surly's answer to those times when you just need to escape to the woods for a while to get away from the humdrum of life. Those familiar with this steel mule know it’s designed around plus tires, previously of the 29” variety. A fully loaded 29+ bike is an excellent way to explore and get away for a while… if you’re of a certain stature that is. For smaller riders, it poses several challenges though. And no one wants new problems when they’re in the woods trying to escape old ones. To solve this, Surly redesigned the smaller sizes of the ECR to work with 27.5+ while the larger sizes are still equipped with 29+. All you medium specimens out there get your pick of the litter as Surly is offering that size in both options. Other updates to the ECR include and are limited to: Gnot-Boost rear spacing and a killer new beige paint job. It retains the abundant accessory mounts that we all know and love like Surly Trip Guide for brakes and derailleurs, fender, rack, and Bill/Ted eyelets, and a Rohloff torque arm slot. The 29+ sizes have two water bottle mounts and one set of Three-Pack bosses. You’ve got lots of options to bring all your “necessities” with you and still have room for excess baggage if you’ve got it.

Surly Wednesday Frameset
$650.00
Wednesday is a frame with a decade of Surly's Omniterra design experience distilled into one steel package. Wednesday can ride over the same type of pretty much anything all of their other Omniterra bikes can, but they borrowed elements from both their Trail and Touring categories to create an Omniterra ride that can truly handle anything you want to attempt. Want to point the thing down a mountain and roll those dice? Wednesday has geometry spry enough to get you through the techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish when you have to ride back to the top. It also has the chops for any sort of expedition you may want to undertake. It has plenty of bottle mounts; triple bottle bosses on both fork legs and the down tube; standard bottle mounts on the seat tube and underside of the down tube; plus rack mounts on the frame and fork and fender eyelets on the dropouts, along with barrel bosses on the crown, fork legs and mid-blade, thru-blade eyelets on the fork as well. It also has internal dropper post routing and Surly Trip Guides to manage all the housing and cables on your frame with style. Wednesday also has its very own dropout design as well – a rear-facing, slotted dropout that can use either 10mm or 12mm axles and exit rearward or vertically. They’re cast steel and spaced at 170/177mm. Wednesday gives you a lot of options in the tire clearance category. In the full-forward, short chainstay position you can run 26 x 3.8? tires on 80mm rims and in the full-rearward, longer chainstay position you get the option of 26 x 4.6? tires on an 80mm rim. Wednesday is made out of Surly's own proprietary 4130 CroMoly steel and is ED coated for extra protection from the elements.
Surly Wednesday Frameset
$650.00
The Wednesday is the result of over a decade of Omniterra design experience distilled into one steel package. It can easily ride over or through most anything our other Omniterra bikes can and then some. With the Wednesday Frameset, Surly borrowed elements from some of their Trail and Touring models to create an Omniterra whip that can truly handle anything you want to attempt. Want to point it down the side of mountain? Go ahead, roll those dice. And if you make it to the bottom, you’ll be able to ride back to the top for round two. Wednesday’s geometry is spry enough to get you through techy stuff, stable enough for the fast stuff, and doesn’t feel sluggish on terrain-crawling stuff. While Wednesday is plenty confident on terrifying terrain, it also has the chops for any sort of expedition you may want to undertake. Surly gave it all the necessary braze-ons and mounts for whatever accoutrements you feel necessary in your travels. Racks? Front and rear, friend. Fenders? You got it. Bottle mounts? How does triple bottle bosses on both fork legs and the down tube, and two sets of standard mounts on the main triangle grab you? They even gave Wednesday internal routing for a dropper post and Surly Trip Guides to keep everything nice and neat and free of rat’s nests. In the dropout department, Wednesday uses a cast steel, rear-facing, slotted dropout that can exit either rearward or vertically. They’re compatible with either 10mm or 12mm axles and are spaced at 170/177mm.
Surly Ice Cream Truck Frameset
$825.00
The Ice Cream Truck goes where most other bikes can’t. Snow, rocks, mud, sand — you name it, and chances are, someone has ridden it on an Ice Cream Truck. Don’t let that terrain-crawling ability fool you into thinking the Ice Cream Truck is slow and sluggish, though. A long top tube (best paired with a short stem) and short stays make it trail-approved and ready to rip. And with 4.8” tires on 100mm rims, “trail” is relative. Show a snowman who’s boss, ride through a sand castle — all while riding the perfect get-away vehicle. Or you can stick to riding terrain that won’t ruin a child’s day. It all starts with Surly's proprietary ED-coated 4130 CroMoly steel. ED coating provides a solid foundation for paint externally while adding a layer of corrosion protection internally. The Ice Cream Truck’s frame is symmetrically-spaced at 190mm and features Surly's MDS dropout system, so you have the option of running a 197mm thru-axle, 190mm geared or a single speed rear end. Each frameset comes with all three MDS chips so you can choose your own adventure. A 132mm wide PressFit 41 bottom bracket allowed Surly to play with the stays a bit more and move them a little further out, creating a much stiffer rear end. If you feel like swapping out the included suspension-corrected, straight blade fork, you’ll have plenty of options thanks to the Ice Cream Truck’s 44mm headtube. In a world full of uncertainties, there’s one thing you can count on: Ice Cream Truck will really take you places. At least when it comes to riding a bike — it can’t do much to help you fix the rest of your life.
