Singular Puffin fat bike – first impressions + photos
Thanks Aidan. What’s the rough weight and build cost from scratch?
I suspect the classic beaches and blizzards marketing fat bikerists do doesn’t really help their cause. If I bought a fattie it would be as a trail bike.
Update when you have more miles in please.
I agree with BB re looks, that’s a big plus.Posted 4 years ago
Note: If you’re thinking “Who needs a fat bike in the UK? blah, blah, blah!” My response is this:
1) They’re fun
2) About half way down this list: http://www.alaskaultrasport.com/race_roster.html
I picked up my Singular Puffin fat bike yesterday, and went straight into two test rides with a nominal amount of work in-between.
First impressions are that it has a very lively ride: easy to manual and throw about. Geometry also works well for climbing, but it’s not exactly a rocket up the hills. That said, the dusty loose bits of Swinley can now be approached with a “Straight up the middle” rather than a “Desperately seeking grip” approach. I’ve currently got On One tubes weighing in at 700g each, so it’ll probably climb better without 2kg of rubber around each wheel(!).
The top tube is pretty dropped which is great for the aforementioned throwing about and also for snow. A common Iditarod scenario is failing to float on some mushy snow; having to put a foot down; said foot going straight through the snow; and balls getting whacked on the top tube. The Puffin allows a bit more space before you get whacked.
The cornering performance is great, encouraging you to get over the front and aggressive in the turns. As with any fat bike, there is some initial resistance as the tyres push against the turn, but you have frame geometry in your favour. Pretty soon the Puffin has you cornering hard and wondering if there is any limit to the grip offered by those massive tyres.
I still need to mess around with tyre pressures a bit more as tiny changes make a big difference when the tyres are so big. Can’t wait to go bash it into some rocks in Wales next week!
The build is:

Sam’s going to be doing pre-orders for the production version, so contact Singular if you want in on the action!Posted 4 years agotazzymtbMember
Did you have to take a hammer to it to tweak the clearance in the rear like the pre-production versions or is this the final finished ready for market all sorted version. Looks lovely be interesting to see what happens with fatties this year with genesis caribou, on-ones at silly prices etc…. should see rise in fat on the trails.Posted 4 years ago
Weight is fairly hefty at the moment. The revisions for the production version will mostly be about reducing weight.
Unfortunately, I don’t really know about costs either. This is a fairly high-end build since the parts are what I will race in Alaska. Sam was talking about sourcing some far-east hubs to be able to offer a cheaper package than using Hope. That’s not confirmed by any means, though.
gee – certainly! Maybe sometime in September?
taz – this is one of the first batch of protos, so it has had some treatments to get the crank clearance. It turns out that Tessa the beagle is not scared of angle grinders. That’s clearly another change for the production version 😀Posted 4 years ago

piha » Nice report and good looking Fatty you’ve got there. I had a ride around the Gorrick course at Minley last night on my 9zero7 and it was great fun on the Fatty.
I’m not sure 100 miles on a Fatty though!
My record is 80.
My record is 1000 🙂

It’s a bit hard to say. In the past I’ve only ever used Endomorphs and Larrys on 65mm rims.
The Husker Du looks comfortable enough on the 100mm rim i.e. not overly stretched to fill the width. It’s been awesome in the dry, and I’d say an improvement on the Surly tyres I’ve had in the past.
Pretty sketchy in very wet/muddy conditions as it doesn’t dig in enough to find grip. But that’s been true of every fat tyres I’ve used.
Why are you going for 100s? I picked them for snow use. For normal trails, you might be better off with 80s. Less weight, but still pretty wide.Posted 4 years agoKeefMember
Huskers on 80’s work very well in all conditions,not bad in mud,but not as grippy as a Nate.Posted 4 years ago
Tried Nates,HD’s and larrys,larrys best and fastest on sand,or hard pack,Nates on mud,snow and very loose loamy/wet roots.
HD’s do all of the above,but not tried them in snow as yet…..

Thanks for Your answer.Posted 4 years ago
I’m mot sure which width I’ll go for. I live in northern Finland, 7-8 snowy months per year. And I weight 95kg. I guess a 100mm rim might give me some advantages on winter, but only with a good tyre choose.
Puffin’s frame doesn’t accept the widest rim/tyre combinations, I’ve understood. So propably I should play it safe and go for 80mm rims.
On the kickstarter info site it says:
“Frame clearance for 26×4.7? tyres (Surly Big Fat Larry on 80mm rim) Fork clearance for 26×4.8? tyre (Surly Lou on 100mm rim)”
I must admit that I’m only still reading/learning these fat rubber issues, and being mostly confused. I’ve read the rim+rubber=width chart given by Surly, and also what Salsa says on it’s site about different crank options… Glad I still got time before the frame arrives.Posted 4 years ago
Received this from Middleburn
At the moment we do our X-TYPE cranks with the option of a 100mm axle.
We also do a 108mm axle which requires a 4mm spacer either side of the
bracket. This moves the crank arms out 4mm per side.
We are working on another version which has more offset in the forging
and is 10mm per side further out over the current version.
These should be available very soon
Could be an optionPosted 4 years ago
My plan is to go with a Middleburn HT2 offering.
I spoke with Matt last week. He was hugely helpful and advised that coupled with the multiple crank options the choice of spiders and rings should result in a pretty spot on chainline in most applications.
Middleburn for the win.Posted 4 years ago
