Introducing Bucksaw


After three years of development, we’re excited to introduce Bucksaw, our full-suspension fatbike!

Bucksaw 1


Bucksaw 2

Bucksaw is a new breed of mountain bike that takes the best attributes of fatbikes and blends them with the proven benefits of Split Pivot™ full-suspension. Floatation and traction are further enhanced by bump absorbing suspension that features a properly tuned leverage ratio and damper unit, in a layout that yields great pedaling efficiency and exceptional braking performance.

Bucksaw will change the way you ride. Every obstacle will be encountered with increased traction and stability. Your choice of lines will increase exponentially, only being limited by your sense of imagination. As long as you can provide the power, Bucksaw will supply the traction.

Where does Bucksaw thrive? Start your list with places where trails don’t exist and go from there. Now add in pretty much any trail in the world, whether dirt, sand, or rock. Picture open country with slickrock to ledge transitions, and big sandy washes. Head out into a vast expanse and let the big fat wheels and efficient suspension do the talking.

Bucksaw. Redefining boundaries.

6066-T6 Aluminum Front Triangle & Chainstays
Top-shelf, double and triple-butted, heat-treated 6066 Aluminum tubing; Formed and shaped for optimized and appropriate stiffness, strength, and weight

Carbon Seatstays
Increased stiffness and lighter frame weight than aluminum

Split Pivot™ Rear Suspension
Ground-up application of the Split Pivot suspension design to solve fatbike design challenges/opportunities

The concentric rear axle pivot in conjunction with precise wheel link, brake link, and control link placement, results in several performance gains:
• Exceptional bump compliance
• Maximum traction
• Incredible pedaling efficiency
• Predictable braking
• Elimination of unwanted suspension movement during acceleration and braking
100mm of Front Travel
Designed around the RockShox® Bluto™ fork at 100mm of travel

100mm of Rear Wheel Travel
100mm of rear wheel travel, combined with 3.8” fatbike tires, makes the Bucksaw capable of taking on incredibly diverse and challenging terrain

RockShox Monarch™ RT3 Rear Shock
Custom-tuned for Bucksaw

Maximum Rear Tire Clearance
Designed for use with 3.8” tires on 82mm, or narrower, rims

Tapered Headtube
Combining the tapered headtube with the large downtube greatly increases the front-end stiffness and strength of the frame without adding significant weight

Bottom Bracket
PressFit 41 (121mm width – same as used on Salsa Beargrease fatbike)

177mm Rear Spacing
Equivalent to 170mm rear spacing, but thru-axle design adds convenient hub catches that make wheel removal/installation easier; results in a properly aligned drivetrain for optimal shifting performance

Front Derailleur
High direct mount, 2x, top-pull only

31.6mm Seatpost/35.0mm Seat Tube
Dropper-friendly diameter with stealth routing. Get loose!

ISCG-05 Tabs
Allows mounting of 1x and 2x chain guides for added chain security when the going gets fast and rough

Water Bottle Friendly Layout
Front triangle design provides space for full-size water bottle

Cable Routing
Full-length housing; 1x, 2x, moto/regular, and dropper/stealth dropper routing compatible

Four Sizes
Small through X-Large sizes; exceptional standover clearance

I love being outside. I prefer to ride on dirt. Or snow. If I was born a hundred years earlier I might have been a polar explorer. There's a great natural world out there to see, smell, taste, listen to, and experience. Life slows down out there and the distractions we've created will disappear if you let them. Give me a backpack and let me go.

Salsa continues to impress with innovative design…. I think some what underrated?

But, that’s ok… Speak softly and carry a BIG BUCKSAW I always say!

Congrats Team Salsa.

Scott Fitzgerald | April 10th, 2014

I’ve never been one to take other people’s word on things but when the Salsa guys told us how amazing this bike rides as an everyday trail bike I was convinced this is a viable new platform.  Can’t wait to ride one - looks great!

This is awesome. I will be placing my order as soon as I can! When can we expect to geometry specs?

Kathy | April 10th, 2014

Rode the Beargrease (an awesome ride!) in the West Yellowstone Equinox event a few weeks ago and now I’m looking to ride a fatbike across the Meseta de Somuncurá in Patagonia.  A crazy idea but there it is—and this looks to be the bike for it.  As we say in Wyoming ... yeehaw, let ‘er buck.

Diego | April 10th, 2014

Well done! a dream come true. I can’t wait to try it!
Thank you Kid! Thank you Salsa!

Sanny | April 10th, 2014

I’ve been waiting for this bike to be made ever since I started taking my Beargrease into the Scottish Mountains. A ride last July knocking out 6 Munros near Aviemore on the Beargrease convinced me that a full suspension fat bike could be the ultimate bike for big mountain riding…..hmmm. I’d better start saving!

Kid Riemer

Kid Riemer | April 11th, 2014

Thanks very much folks for adding to today’s excitement. I’ll address the questions that I can now.

Weight - Bucksaw 1 size Medium pre-production bike that we have at Sea Otter weighed in today by BikeRadar at 32 lbs 6 oz.  We aren’t sharing the weight of the size Large gold one because it has some non-spec parts on it, including some prototype carbon tubeless rims from Whiskey Parts Co.

Geometry - We aren’t sharing the bike geometry until later this summer. I’ll be straight up with you…we put a lot of work into this bike and there is nothing to gain from us sharing our numbers with our competitors at this time. Bucksaws will be available in Small, Medium, Large and X-Large sizes, and fit the way our Salsa mountain bikes fit. So that should give people an idea of the size they are looking for. Then, later this summer we will release the geo numbers.

Frame Only option - Yes, there will be a frame only option.

Colors:  Blue and Gold. Sorry no Black version planned.

Salsa Dealers will be able to start ordering these bikes at the SaddleDrive dealer event this July. Again, the bikes are slated for Fall 2014 delivery.

One quick thank you. I’m typing this from the motel at Sea Otter after having a very exciting day launching Bucksaw. It wasn’t until after dinner tonight that I saw the comments and questions, and Facebook posts about this bike. THANK YOU! Your interest helped make a great day even better.

JYB | April 11th, 2014

Can this frame fit Knards on Rabbit Holes???

Kid Riemer

Kid Riemer | April 11th, 2014

JYB -No, Bucksaw doesn’t fit 29+. The Bluto fork will accept 29+ but the rear end of the bike won’t. The outer tire diameter difference between 3.8” fatbike tires and 29+ tires is too great.

No avatar image

Loui | April 12th, 2014

The bike is really great! Thanks to Salsa! But i´m also a big fan of 29+ bikes, and so my question is: are you planning a 29+-FS-Bike in the same design? Thank you, Loui

CJD | April 13th, 2014

You guys at Salsa have it so totally figured out that you are competing with yourself now.  I was sold on a Spearfish after riding a 2014 at a demo in AZ.  Then Kurt Refsnider tells me how much fun the 2014 Horsethief is and I start looking into that and convince myself that is the bike I want. Then this beauty shows up!  Now I have something else to keep me up at night again but I can’t wait until September.  Great job guys!

Brilliant bike. Is there any chance that you’ll also offer an XS size? I think the small will fit me, but my wife who is 5’ 2” will likely need an XS.

CJD | April 14th, 2014

What does Salsa envision this bike’s PRIMARY purpose to be?  General trail bike?  Bikepacking? Snow bike?

No avatar image

Ronnie Mac Jr. | April 14th, 2014

CJD, I’m sure that Salsa envisioned this bike to be a money maker. They were smart, and recognized that this is exactly what the market wanted. Face it, most people do not do a great deal of riding in deep snow, but tons of folks are riding their fatbikes year round on the trails. It was a savvy move.

Kid Riemer

Kid Riemer | April 18th, 2014

CJD and Ronnie Mac Jr - The Bucksaw is aimed at dirt…and rocks…and roots. We did not approach this as a snow bike. Snow trails are smoother than dirt singletrack, and that is also where running really low tire pressure becomes important: floatation.

Think of Bucksaw as a mountain bike/trail bike that just happens to be a fatbike.


Think of Bucksaw as a fatbike that just happens to be a full-suspension bike.

Having ridden Bucksaw on Porcupine Rim in Moab this past Tuesday, I can say that Bucksaw absolutely killed it on that trail and in that terrain. The big, wide tires provide immense stability and obscene amounts of traction. Those traits were valuable both descending and climbing up technical bits. I could change lines at will. I could take lines I wouldn’t take otherwise.

At the same time, I should relate that last fall…riding a Split Pivot Bucksaw proto with pre-production Bluto on a technical trail THAT I HAD NEVER EVER CLEANED BEFORE…I made the entire 3-mile loop. No dabs.

So, while yes I am a marketing guy, I will say that Bucksaw is no joke. This is a serious machine with incredible capabilities. Thanks for your interest.

David | April 22nd, 2014

my girlfriend’s looking at me oddly ... it seems I’m making sounds that I usually only make with her! So it looks like aggressive all-mountain mix with greater trail capability? What’s this thing like in the air? The geometry “looks” like it could handle some serious down-hill - or is that asking for too much cake with icing and cherry on the top?

Eric | April 23rd, 2014

will you be at dirt fest? and can i demo a bucksaw there?

No avatar image

CJD | April 24th, 2014

Since I have your attention Kid…

I need a Swiss Army knife bike.  I want it to be good for bikepacking on the CT and AZT while still being a fun general trail/endurance bike for every day use.  It is going to be a Spit Pivot FS from Salsa but which one?  The Spearfish seems a little more XC/race oriented while the Horsethief seems more trail bike but maybe not as good of a choice for bikepacking ? and the Bucksaw is???  I really wish I could ride these bikes and find out for myself.

No avatar image

Mike | April 30th, 2014

Well done guys the dream has been completed, that is all we would talk about why has someone not come up with a fat tire for riding on dirt. I am going to have to demo it when I find it. Congratulations again. On another note could you guys produce the Fargo in carbon fiber, I love mine but man could you imagine what it would be like in a light weight material. Keep up the good work!

Matthew Englert | May 8th, 2014

I cannot wait to ride one! Love the new X01!

Kid Riemer

Kid Riemer | May 8th, 2014

Eric - Salsa will be at Dirt Fest but unfortunately we won’t have a Bucksaw there. The few we have are all on assorted missions currently.

CJD - I’ll paraphrase Dave Weagle here…“There is no one bike that will make everyone happy.” I’ll take your question and ask you a few questions in return that might help you find an answer.

-How important is speed to you?
-How important is maximum all-day, long, long ride comfort?
-How gnarly is the terrain you will typically ride?

Each of these machines (Bucksaw, Horsethief, Spearfish) has unique characteristics. In my opinion, each one of them is totally capable of being an excellent bikepacking machine. Personally, I’ve used my Horsethief that way and it rocks. It is very efficient.

Watch our Events listings on our Facebook page, as hopefully there will be a demo near you so you can try out the bikes.

The RS Bluto fits 4.8 tires….

Kid Riemer

Kid Riemer | July 17th, 2014

Russel and Shark: No, the Bucksaw frame is specifically designed around 26 x 4” (common designation for 3.8” tires). The Bluto fork can however accept 5” tires. You can read more about the Bucksaw this coming Monday and why we went that way, but I’ll cut to the chase and say that the tire sizes and ride characteristics are vastly different between 4” and 5” tires. We decided to optimize the Bucksaw around 4” tires rather than making compromises to the bike’s final ride quality in order to fit 5” tires. Thanks for your interest.

Longbiker | July 22nd, 2014

This looks to be an incredible machine. Demoing this week, I am so stoked.

No avatar image

Russell | July 22nd, 2014

Thanks for the replies.  The Bucksaw frame cannot accept the 4.8”-5” wide tires.  The Bucksaw frame can only accept up to 3.8”-4” wide tires.  But the RockShox Bluto fork can accept up to 4.8”-5” wide tires.  I suppose you could run a 1” wider front tire than rear tire.

Kid Riemer

Kid Riemer | July 24th, 2014

Edgeworker - Depending on terrain we would suggest between 8 - 12 psi.

Joseph - Whiskey has announced a tubeless carbon rim…and 45NRTH a tubeless fatbike tire. So there you go…

Everyone - Note that we now have Bucksaw’s in our Salsa demo fleet. Check out of our Facebook events listings to see where the truck will be. And again, thanks for all of the interest in Bucksaw.

Brenden | August 18th, 2014

I understand that the Bucksaw is designed and aimed for dirt/trail riding, but I’m hoping someone could comment on how well, or poor, the Bucksaw will perform as a sand and snow bike.  Given that the bike shines as a trail bike, will it be ridable on beaches and on snow as well with lower tire pressures?  Or is the geometry just not right?  Also, what are the temperature limitations of the suspension and hydrolics (0-30 above)?  I ask because I’ve wanted a fatbike since moving to MN about two years ago and now I’m moving to the coast of Maine.  Seems like the Bucksaw might be a great solution to Maine’s roots, sand, and snow.

Thanks in advance

Kid Riemer

Kid Riemer | August 25th, 2014

Pete - Please let us bring the Aluminum version to market first. Then we’ll go from there.

Kid Riemer

Kid Riemer | August 25th, 2014

Brenden - Bucksaw in snow and sand? The geometry will be just fine actually. Performance in cold weather? That is really more a function of the fork and shock internals than the frame design. There are a few things we do know: cold weather makes fluids like oil ‘thicker’ which can affect compression and rebound. I believe RockShox is offering a cold weather conversion kit for the Bluto, though I don’t know the specifics of it.

Of course, there are folks (including some of us) that have ridden full-suspension or front suspension bikes in cold weather before for many years.

Personally I’d probably be somewhat cautious about using Bucksaw in an ocean beach environment, simply because salt is so corrosive and even riding in the wet sand is going to put your frame, fork, shocks, and drivetrain through the grinder. I also don’t know for sure what salt water does to a suspension fork or shock, but have a hard time believing it wouldn’t create wear.

I hope that helps. Thanks for your interest in Bucksaw.

David Miller | August 25th, 2014

Loving how these are coming along :)

Here in New Zealand one of these would be awesome as an all-weather / all terrain toy. We have beaches, lakes, forests, downhill, trails, snowy mountains - you name it, we have it all within a couple of hours’ driving :)  For beaches ... simple: just need to be disciplined and wash the bike down with a gentle pressure after riding. All of our beaches already have hose-down stations plus it’s not that different from rinsing the scuba gear :)

And finally I REALLY DO have a VALID FUNCTIONAL requirement for spending the $$$ on an enclosed gear-set. Now we just need air shocks and forks and then it’s time to write a letter to Santa :)

Picked up my Bucksaw 2 last weekend and have been on a couple of rides.  First was local single track up here in Ipswich.  Ran the bike with 10lbs front and back and it was very nice.  Took it over some side hill terrain with lots of roots and it handled everything very nicely.  Yesterday, I took it out to Cranes Beach in Ipswich for my first ever beach ride.  Ran it with 8 lbs for half the ride and then let some air out.  Checked when i got home and i was at 4 lbs psi.  That worked really well.  Rode for an hour on the beach……awesome, even on a cold rainy day.  Really fun bike.

Kid, we love our Salsa bikes. I’m with CJD in wanting a 29er + full suspension.  I just sold my Spearfish 1 and have a 2014 Mukluk 2 I ride single track up Noth from May till Oct. Then I’m down here in FL. I am getting ready to mount uo Hugo 26” wheels to my hubs and then I’m going to make up a 29er + Hugo wheelset.  I love my bike but as soon as someone makes full suspension 29er + frame I’m going to jump on.
