Today is a good time as any to give my review, as the whole house is down with the sickness 🙁

So I was able to borrow Jdogs Krampus over the holidays which is where I give it a good shakedown on the mooch trail system. Not to mention my last 2 city commutes.

I had a few of those moments where I thought about the N+1 would be a fat bike, but those parking lot rides of those I rode were uninspiring. I was totally intrigued by the Krampus though when I first read about it, yes I read all 68+ pages over at MTBR.

Why, because it was a platform I was on board with. Rigid, SS capable and steel. As I have gotten older I favor simplicity over the latest greatest bouncy carbon things.

The Bike is is Surly's 4130 CroMoly steel, with room to fit there 50mm Rabbithole rims and the Knard 3.0 tires. A slack 69.5 HT 72.5 ST 44.8 WB for the large I rode. What this equals was a extremely stable machine. Low speed pick your spots stop then go, though I was missing the engagement of my king hub vs. that of the DT Swiss that Jdog had. Here is where the bike really shined, when you pointed it down hill on those fast descents. Butt puckering oh shit moments yet never losing control. The massive Knard tires beg you to lean over in turns and I mean lean way over, I don't think I ever had a bike that could be laid down that low unless it had a throttle. This bike will not win any weight weenie awards which is fine with me but really for such a big bike it never felt sluggish. Fact is once you got up to speed this bike begs to just rip.

I was able to put it through as much disciplines as I could though I missed out on a true snow ride. What impressed was the slow crawl up wet rocks and gnarly roots. Krampus is truly an all day adventure/fun bike. I wondered how the tires would react to the road so I did a few rides from the house plus city commutes and other then the cool buzz the Knards roll quite well. I could defiantly see this as being "if I could only have one bike" to fit that bill. For NJ riding where you don't have 2 hour climbs and all winter snow this bike makes a lot of sense.

Surly once again hit a homerun with this new 29+ platform and already has others jumping in with frames wheels tires and specific parts. And why is this better to try then a fat bike because you can swap over all your standard 29 parts.

Get to your local Surly dealer and demand a Demo, you will be glad you did...

It should also be noted that I really appreciate Jdog letting me have an extended demo of his personal ride, that right their is why he is top dog in NJ....
 
What about tire selection and price?
Can you put a suspension fork on?

Tires at this moment are just the Knards but surly has a new one in 2.8 size and vee rubber has one coming also.

suspension forks are pretty nil not that I care. Seems that fox 29er forks from 2012 and newer work though still a slight buzz. I put it on my 2011 fork with no success. It did fit my Niner fork with plenty of room to spare. Once again lefty has been the choice by many. Still I didn't feel the need for a fork. This tire does not show in pictures like it does in person, it makes regular 29er tire look tiny. I ran 12psi front and 15 psi in the rear.

Rim choices will be plenty in the coming months with stans entering with a 52mm and velocity with a 47mm.
 
Since this is my bike, I figured I would chime in on this a bit.

I had a 26" fat bike for a few months last year and I couldn't get happy with the crazy tire roll that I was experiencing. Basically with fat 26" tires I found that they would slosh around so much in the corners that it just wasn't fun for me.

I quickly sold off that bike once I had one very short ride on the Krampus last winter.

I will just ramble here about my findings.

-No one wants this bike for some reason. Everyone seems to feel that fatter is better. I didn't find this to be the case.

-If you like the rolling feeling of 29er, you will love this. It is a momentum machine. Much more so than 26" fat (IMO).

-Mine is setup tubeless. Tubes are silly.

-Good brakes are a must. There is a shitton of wheel mass spinning.

-Great in 3-5" of snow, better on packed snow. Maybe slightly less capable in deep snow than 26" fat, but good enough for where we live.

-This thing has traction for miles and it caries speed.. like too much. Sometimes you feel like you are riding a bull. Not completely in charge of what is going on.. It feels good.

-You can run 29 x 2.35 tires on the rabbit hole rims. Pretty neat actually. On of my shop guys has a Lefty with a rabbit hole/ 29. 2.35 Knobby Kick on the front.

-I MUCH prefer the narrower / Standard cranks that this bike allows for. I found that "standard" fat bikes feel like you are riding a horse.

-To answer mr Short, I have seen pics of suspension forks on this frame.


I am not a huge fan of a few small points on this bike:
I don't prefer the horizontal dropouts. I think the seat tube angle is too slack and that the headtube is too long. It is heavier than it needs to be.

I pulled my kid on the canal on this bike a TON this year. Not sure of the miles, but it was a ton of hours. Basically the math is 25lb kid, 30 lb trailer, 30lb bike= strength training.

This bike, like all fat bikes get comments and stares whereever it goes. I have been giving thought to building a lighter version of this.

Derrick out on Oyster bay, rides a 26' fat bike with 29er+ wheels in it. He might even chime in. I know that he is also a big fan.
 
I was a little mad at surly for announcing this right after I ordered my ogre. Thats a great frame but krampus adds even more possibilities.

I can't imagine riding cranks with wider q than normal mtb. I think my knees would rebel. And in general, I like that this bike uses normal parts.

Rear dropouts are not so bad, but i'd prefer vertical as well. Easier to pull wheel on multiring setup (shift to small / middle ring) than on 1x or ss. Yes, I've run ogre in all these configs.
 
They're neat bikes. Obviously I prefer a true fatty over this just because of the terrain options you get on a traditional fatty. I can ride my fat bike literally anywhere, trails or not, in any condition.

Unfortunately even the smallest frame size in a Krampus is quite large. I've ridden a small around a bit and just couldn't get over how tall the bike was. This is where running a 29+ wheelset on a fatty is a better option. A true fat has a much lower BB and significantly better standover. Also running a 29+ wheelset on a true fat will be a ton lighter. Everything Surly makes is 20 pounds too heavy compared to anything else on the market.

Just the .02 from a fatty perspective.

-Jim.
