Jeff & Paige's 29 Plus Tandem

This project was really fun for a lot of reasons. Not only was this my first tandem build, but it was for a good friend, and that is always cool. I worked for Jeff back in my engineering days. He is a super talented designer and it is really cool to have his support now that I am doing the bike thing full time.

Anyhow. The other exciting part was designing and building a 29+ tandem. This is Jeff and Paige's third tandem, and they actually do quite a bit of off-road riding. I think the big plus wheels are going to be awesome for addressing many issues that are normally seen on two-seaters.

We went with a 1x11 drivetrain, which allowed us to run the timing chain on the drive side and use modern MTB cranks. This was very helpful in dialing in tire clearances and chainlines. The 140mm Fox fork just clears a 29+ tire. Other build highlights are the Industry Nine/Velocity wheelset, Smooth Move bars from Rick Hunter, XT drivetrain with Zee brakes, and matching stems by me.

It was awesome to see how stoked these two were when they came to pick up the new bike! I am gald it is sticking around Bozeman so that I can see it from time to time. Can't wait to see the adventures it goes on!

Andy's B+ Bike Packer

Andy wanted a cool bike for daily riding on the front range as well as something that could take him farther. This 275 plus bike can be run rigid, with lots of mounting points for bottles and anything cages, or with a 130mm suspension fork if he wishes.

All around a comfy, playful nimble bike that can handle it all from a quick spin on the trail to a big bike packing trip!

All Road Gravel Crusher

This all around gravel road crusher is the bike to do it all. The geometry is dialed for efficiency during long days in the saddle. Comfortable handling for rough stuff and singletrack lend themselves well to the all road position as well.

Don't be fooled by this bike's massive tire clearance though. Throw on the skinny tires (or dont) and take this thing to the race course for some fun weekend races during cyclocross season.

Toffer's 27.5 plus Mountain Bike

This bike received Best Mountain Bike at the North American Handmade Bicycle Show 2017

Toffer approached me looking for a bike that he could use to explore the trails in his new home in Missoula Montana. He wanted a capable and versatile mountain bike that would not only perform well in Montana, but something that represented the culture of self reliance and Independence that attract so many folks to this state. We went with silver and gold components from a number of domestic companies like Paul, Industry Nine, and Chris King.

Much like myself when I moved to Montana, this bike is sold on single speed. That said, if the big mountains prove a little much, Toffer will have an easy switch to gears with stealthy internal routing and a simple Paragon slider swap. The suspension corrected fork can easily be swaped out for 130mm of suspension if that is desired as well.

Guest Review - Colin's B+ Adventure Bike

This is a review written by a Customer and friend, Colin, who's bike I built in the summer of 2016. I love hearing feedback, especially this kind. Enjoy!

Words By Colin Frazer

In 2015 I moved to Bozeman, Montana from Austin, TX for a job in academia.

Young academics tend to move a lot and the process of assembling a new community every few years is pretty tiresome. Luckily for me, I quickly found a bike shop in town that had a vibe that I immediately got along with: Alter Cycles is friendly, laid back but professional, community oriented, throws weekday rides and weekend parties, all in a small nicely designed warehouse space.

When I first walked in I had that overwhelming ‘these are my people’ kind of feeling. Not only that, but next door is Adam Sklar’s shop where he builds handmade steel frames, one at a time, day in and day out when he isn’t eating tacos.



What began as friendly conversation between Adam and I quickly turned into the sort of riding friendship that I luck into every now and again. He and I shared an exploration-oriented, ride-from-town kind of vision, plus it turned out that he could not only build bikes, but shreds pretty well too—we started to ride together fairly often.

As a long time MTB’er from Colorado and Oregon I’ve mostly gravitated towards hardtails in my time. I like the workingman’s efficiency of them, the grunting (or pushing) up steep stuff, charging climbs, picking precise lines down the tech stuff. I don’t mind limiting my speed a little bit on the descents for a bike that is simpler, requires less maintenance, and climbs efficiently. The more I got to know the local riding in Montana, the kernel of what I felt constituted the perfect Montana bike started to take shape, and it was watered by new technologies and trends in the industry including bigger tires and wider, stiffer wheels.

Custom steel plus bike

You see, the riding in Montana is crazy good, it basically has it all: from loam to desert, flow to tech, it’s not hard to find places to get stoked here and ride them from town, plus you're more likely to happen on wildlife or huckleberries than other people. The rumors are that the riding season is super short here due to snow, but (shhhh, don’t tell) there are plenty of low-elevation deserty places to get your fix, even in February. A lot of the riding (like most of the mountain West) involves long climbs (often steep) followed by really long descents that are often pretty chunky due to the lack of bodies to do much trail maintenance in a vast state with just over a million people. My ultimate Montana bike had to be efficient enough to get to and from some of the farther out of town trailheads, but burly enough to deal with the punchy, loose climbs and fast, steep, chunky descents. But I also wanted it to be great for the many options for overnighters here, and even multi-day tours. More than anything, the bike needed to take advantage of the B+ platform to make the shreddiest hardtail possible for all our variable conditions.

275 plus hardtail

So Adam and I started talking about this dream bike every now and again on our various rides because he'd been thinking about a similar bike. It would need to be slack and low, built around a big front end, and maximize front triangle space for bags. It would need to be stiff and long, but still nimble. Building it on a plus platform would give it the extra grip in muck of Spring and allow it to ride packed snow trails, all while providing some extra cush to the rear end while sending it through the mank.

I’ve now ridden this bike for several months and I think that Adam pretty much nailed it with the geometry. To say this bike shreds is an understatement. I’d venture that it descends faster than any hardtail you’ll find, it’s an absolute screamer through anything but the gnarliest of sections, and makes you question whether anyone *really* needs a full squish. In loose, flat corners the extra contact surface inspires confidence—it’s giggly fun in flowy fast sections. Like any bike with a longer wheelbase, it takes some getting used to on the climbs, but the amount of grip you have in the rear makes the thing feel like a rock-crawler! Having ridden this bike now in Montana, Washington, Oregon, Utah and California, it is clear that this bike is at home just about anywhere.

The details don’t hurt either: Boost spaced Industry Nine rear mountain hub, and a SON Dynamo front hub laced to 50mm wide Chinese carbon 27.5 rims mounted into slick custom anodized Syntace dropouts. An XO/XX1 drivetrain with a Wolf Tooth elliptical ring makes climbing a bit easier, and a stealth dropper with a Brooks Cambium saddle, wide Enve bar and a 50mm 26 Designs stem tighten up the cockpit. The front end is plenty plush with an Alter Cycles tuned 140mm Rockshox Pike taking the hits. The rear end is tucked and stiff: 425mm chain stays to a well-curved seat tube and a T-47 BB ensure this. After blowing through two WTB Ranger tires immediately on this thing (Can’t say enough good things about tire plugs for tubeless plus tires - get you some) I changed over to the newly released Maxxis 2.8 Minion DHF (best tire ever) in the front and a Chronicle in the rear and haven't flatted since.

Final verdict?

This is hands down the best mountain bike I've ever owned. The only problem is that now Adam can’t keep up with me…that is, until he builds one for himself! Hit Adam up for your best MTB ever or to get some details on the geometry.
