Roamer update #5 Build and geometry

I get a lot of questions about the geometry on the Roamer so here is the build and numbers.

My idea about this frame was to get a bit more fun and aggressive fat bike. It´s basically an all mountain hardtail with 4.6″ tires. Ready to fit a 120 mm suspension fork up front for summer and rigid steel fork with anyting-cage mounts for winter bikepacking.

BTR makes the best hardtails in the world so they were the obvious choice for this bike.

I gave Tam my requests and he did the design with a little input from me regarding the fat bike specifics.

Since i ride it like a mountain bike in the summer i went for 100 mm bottombracket and 177 mm rear spacing. It fit 4.6″ tires (maybe 4.8″) on 80 mm rims. I´ve been running Dunder/Flowbeist from 45nrth and never felt i needed wider. And i ride snow for 7 months a year and plenty of beaches in the summer. Also 177 rear and 100 bb make it more like a regular mountainbike.

Roamer update #4 “There can be only one”

After a series unfortunate events the last pices of the puzzle finally fell into place. Finally time to put the Roamer together. I took a day couple of days off from work to build her up. I really enjoy bike building and every thing went according to plan. The only thing that was a hassle was fitting the seat post, but after a few twerks with the cable it worked like a charm. The thing i was worried about was changing the rear break hose. But that was way easier than fitting the post. Shimanos bleeding system is genius and super easy.

By the time i was ready a heavy rain fell and it had started to get dark. Good for me i had another day off work to ride…

Firts impressions, the engineering on the frame is stunning Burf is a genius. When mounting a new bike it takes a while before it’s tuned in. But getting on this was like coming home. Tam has nailed my wishes and it totally lived up to my expectations. It’s exactly the bike i had in mind. Comfortable but still aggressive with the slack 67′ head angle and short 435 mm chain stays. Wide bars and high stack makes it very easy to handle. The Roame is ready to take a 120 mm suspension fork but that’ll have to wait untill next summer. However the rigid fork works like a charm on roots and rocks combined with the 4.4″ Jumbo Jims. It’s rides like a freight train down hill and climbs like a goat. The short rear end makes cornering and jumping a walk in the park. It’s my riding skills rather then the bike that sets the limits.

There were a few people that had thought about if BTR was able to make a fat bike since they never built one before. The thing is fat bikes are mountain bikes and it doesn’t have to be slow and bulky just because it has more rubber.

Once again thank you Tam and Burf at BTR-Fabrications for making my dream come true. Cheers guys you rock!

Can’t wait to get it up to the big mountains in a few weeks.


Roamer update #3 The arrival

Today at noon the long awaited box from BTR-Fabrications landed at work. It´s been a long wait, but well worth it. Un-boxing a new bike/frame is like Christmas for bike geeks, you know the feeling. When waiting this long, and when it´s a custom frame that  is only one of a kind the expectations are pretty high.


Let me tell you, BTR did not let me down.

Here´s what i wrote in the last email…

“Tam and Burf,
Just unpacked the frame. It’s stunning. You guys are not just frame builders, you are artists. So beautiful and well made. 
It’s incredible value for the money getting custom from you guys. Especially regarding how expensive the big brands are with their Chinese made frames. 
Thank you so much, just waiting for tires and seatpost now, but will start building tonight. 
I’ll post an update on the BLiSL site soon. 
When it’s ready I’ll try to get a story about it on and some other sites. It’s a rare bird. 
Once again thank you so much!
I got the delivery guy to drop the boxes at work and here it is. I forgot my camera at home so just Iphone photos, but damn it´s one beautiful frame set. So incredible well made…


The same snowflakes as on the bars sits on top tube and right fork leg. Graphic by the grand master at Oddity Cycles Burnsey. Very surtitle but turned out better than expected.


I can´t wait to get this baby ready and hit the trails. It´s designed for 120 mm travel fork but that will have to wait until next summer. I think it still shreds pretty good with the 67 degree head angle tho. Wheels by the master wheel builder Gav at August Cycles


More to come soon…

The Oddiy upgrade

Sometimes you just fall in love and there is just nothing you can do about it. I did and now i cant think of anything else.

I don’t really remember when i saw the wonderful works of Burnsey at Oddity Cycles. Pretty sure it was on Instagram at Endlesbikegirl or Taddihogg. They both run beautiful Oddity bikes. These frames are hand made in Colorado and is the most beautiful, badass mountainbikes i have ever seen. My dream has always been to have a custom frame and if it happens one day it will be one of these.

And Yes! They make fat bikes.

Check this beauty out!

Morning tracks… #biggrin #odditycycles

A post shared by Oddity Cycles (@oddity_cycles) on

Oddity don’t just make frames. They make the coolest handlebars and forks too.

The Razorbar really caught my attention. Razorbars are old school klunker inspired mountainbike bars in titanium or steel. I just love the look and you get to choose rise, backsweep and width, after all they are custom. I shot Sean an email and wadda ya know! The ship world wide.

I think i have had four of five differet bars on the Mukluk and i have never been completely satisfied. The Razorbars looked spot on.

After a few conversations over email it was a go. I decided to go for 800 mm width with 8° backsweep in steel. My hart screamed TITANIUM but my wallet said; hahahahaha… Yeah riiight, in your dreams buddy.
So steel it is. Not the lightest but i mostly ride my bike. Not carrying it around.

And now a couple of weeks later The White Queen got here new crown. Stunning finnish and feels amazing. I’ve only ride to work yet but first impression is: On my god i love it!



 One day i´ll sell all my bikes and go all in to build up my dream ride. There will most definitely be Oddity parts on it if not i´ll go for a complete frame. Thank you internet for making the world smaller. This would not be possible with out you. Me shopping bike parts from a small custom frame builder across the globe.

And thank you Sean for making dreams come alive with your amazing craftsmanship and excellent service. You sir are a really nice guy but then again you are a cyclist.





Getto Tubeless Beist Master

Since my adventures on the MAXX Jagamoasta last winter i’ve been eager to go tubeless and fatter  on my Mukluk. 

The test bike was equipped with Schwalbe 4.8″ Jumbo Jims but they are very hard to come by. Also i guess they’re too big.

Instead i had my eyes on the 45nrth Dunderbeist. 4.6″ winter tires with massive tread pattern. Also avalible through my lbs since there is a new agent, Nordic Trade, for 45nrth in Sweden. 

My current tires. Vee-rubber Snow Shoes are totally worn out. I’m not at all pleased with their performance and they got loads of self steering and the tread pattern is pretty lame for snow. 

I gave Fredrik a visit on monday and three days later the Dunderbeist arrived. First impression were, they are massive!


Now time to go tubeless. I’ve never done that until i tryed gettotubless on the Instigator. Experimented on the rear wheel and it worked like a charm on the first try.

Should work on the fat bike too. Here is how i did it.

First i bought a pair of 24×4.0″ baby fat tubes from on-one. Need to have a smaller size on the tube compared to the rim.

Then just put it on the rim. No gorilla tape, just the regular rim strip under the tube.

Cut tube open like gutting a salmon. 

Spread it open and put on the tire.


Since i don’t have an air compressor (yet) i went to my lbs to steel some air and put in the tubeless fluid.

Air tight on the first atempt! Cut off the remaining tube. 

The chain line is very close to the tire when on biggest rear cog. We’ll see if it changes when the tire forms up after some riding. Then i might have to change the bottom bracket distances or move the chainring out. 

I did get a short spin. First impression, no self steering! Ok, i ran pretty high pressure but they felt really good. 

Also the look effing kick ass! 


Mukluk upgrade XT 11

This summer has mainly been about the Instigator. This bad girl is a lot of fun and have get it ready for summer i had to rob the fat bike for parts (cassette, rear derailleur and trigger).
This left my fat mistress in summer-rest. I had loads of fun on the Instigator this summer, going to bike parks and hitting the local trails. But, after a while i started to miss those fat tires. The Instigator runs 26+ 2.75″ Dirtwizards but still it feels almost like a ordinary mountain bike compared to 4.0″ tires. Especially on the more technical trails.

A few weeks ago i decided to buy a new drive train and was aiming for XT. I checked in at my lbs and was just about go for the regular XT when it struck me that the new 11 speed was going to be released this fall. I asked my lbs when? Fredrik told me it was already out and yesterday i upgraded the Muk with brand new 11 speed XT.

I´m all about single ring up front and have been riding the Oneup 42 cog upgrade. It has worked very well and even if quite expensive it is a bargain in compared to Srams 11 speed groups. With Sram you also need a complete new drive train including rear hub with special body for the 11s cassette. 


Shimanos cassette fits on regular 10 speed body. I can also run the same front n/w chainring. The whole XT set is also way cheaper then just a cassette from Sram. 

Installing was super easy and it worked super smooth with just a few adjustments. I cant imagine going for nothing else than Shimano. Both drive train and breaks. Maintenance is a walk in the park and cost is very competitive. Hopefully we will see a XT crank set for fat bikes soon. (fingers crossed)

I only had a chance to take a short ride for adjustment. But first impression is close to perfect. I’m planning a longer ride this weekend and will be back with a ride report.

It feels good to be back on the fat bike again. She still is my number one. 


Surly Instigator 2

Ever since i had my On-one 456 I’ve had a soft spot for steel all mountain hard tails. When sold it to buy a full suspension Specialized I’ve kind of missed it. I dont know why i have this weakness for these kind of mountain bikes. Perhaps it is the feeling of old school Going back to basic kind of thing. Or perhaps it’s just that they are badass. 

When Surly announced that they were bringing back their Instigator but this time with 26+ tires and 140 mm fork i put up my full susser for sale. This was the bike I’ve been waiting for. I got the frame last summer but the project had been on ice for the whole winter. Yesterday it was finally finished.

I got the last parts and stolen some stuff from my poor Mukluk to get it ready.

Drivetrain. Shimano Zee cranks with Superstar w/n 32 chain ring. XT cassette Slx derailer. Both upgraded with OneUp 42 cog and rad cage.  


Chris King headset, Thomson stem and Easton Havoc bars. XT breaks. One thing on the Shimano breaks. They are awesome! Super easy to fit. Did not even had to bleed after cutting the cabels. Me like!  

When buying the Instigstor ready built it comes with a Fox fork.  I like Rock Shox so i went for the 140 mm Revelation 27.5. The Dirt Wizards got plety of room. They’re sitting on 40 mm Alex rims, bomb proof! 

Regarding dropper post i wanted the best. I’ve had problems with droppers before so i went for Thomson Elit dropper. However i’m having some problems with that. Digging it to that and will follow up in future blog posts. 

I love the neat little remote.

I can’t wait to hit the trails with this beast. I love my fat bike but when going more agressive it’s a bit bumpy.  


The Superstar saddle is not only super cool it is also quite comfy. 

I’ve just rolled it for about an hour. I will be back with full review in a few week when I’ve got some dirt on it.
