I went off a mild roller in front of my buddy today (who was filming), landed a little crooked and snapped my chiner handlebar clean off. Somehow, I managed not to impale myself with the remaining razor sharp nub that was left. I have watched the video over and over, and can only attribute my correctly torqued stem to having saved me from a trip to the hospital. It seems that when the bike hit the ground,the stem twisted relative to the steerer, pointing the leftover handlebar away from my abdomen.





I gotta thank my lucky stars today...

I'll post the video in a bit...

Fat Bikes / My N019 Build, NASA themed!
« on: October 12, 2015, 06:04:58 PM »
Hey guys.

So, after much humming and hawing, I caved and placed an order with XM Carbon Speed for a N019 fatbike and the 80mm carbon rims.

I spent way-too-many hours on BikesDirect and Excel looking at the Boris and Lurch FS models, working the numbers every way possible, only to conclude that while a BD bike would get me on a fat bike faster, it probably wouldn't make me as happy long term. I think that there's just something about building a bike up yourself from scratch, the way you want. I'm more of a do-it-yourselfer anyway. The other big factor was that I was able to source a trick suspension fork at relatively low cost ($250), doing away with BikeDirect's price monopoly advantage with the Bluto. Big thanks goes there to RSD bikes in Canada for the deal on the fork (they're now sold-out I think, sorry).

I sourced these chiner goodies from Peter at XM Carbon Sports, and I have to say the guy has been pretty awesome so far. They're 12h ahead of my time zone, and he was repeatedly answering emails during the Chinese Holidays about 5 minutes after I sent a question. You can't beat that. I had originally gone to Bert at XMIplay, but he was on travel/vacation and when he eventually, responded my order was already placed.

So, without further ado, here's the build sheet with the costs and some really rough weight estimates:



Some of the philosophy on the build:
Frame - The N019 had everything I wanted, fully replaceable axle mounts, a huge straight downtube (I'm not much a fan of the dragon's-neck shape of most downtubes these days), internal cable routing, etc. The frame looks like a tank too, part of the whole fatbike theme I suppose. At $445, I think it is worth it to just buy the frame directly and have in the build everything fit the first time, versus buying a Motobecane Lurch FS, then trying to swap the frame with an IP-N0XX ( where you'd have to play with hub spacers, axles, cabling, selling a largely worthless Motobecane frame later, etc). YMMV

Fork - Not interested in a carbon or rigid fork, so the only options really were Bluto, Bluto, Bluto or... if you really dig, the "fork of many names". This is an upside down, inverted fork ( USD), similar to those found on sport motorcycles. The fork is made in China by Mekkem and has been rebranded by Carver/Bikeman and eleven9. By everything I could read on it, it seemed like a great, well adjustable fork. People seem a little worried about it flexing about... but after having held it in my hands, I just can't imagine it is a noodle. The uppers and stanchions are simply gigantic, and the axle mounts are completely reassuring. I'll let you know if it actually rides any differently. I managed to dig one up on Pinkbike for a steal, they are available from Bikeman.com and on eBay though.

Wheels & Tires - Fatbikes are all about the tire, so I decided that there was no way I was gonna do this with entry-level tires. It's like spending a bunch of money on a FS frame, and then putting a terrible rear shock on it. Why dampen the fun (pun intended)? This meant 45NRTH tires, and fortunately the 4" Husker Du's clear the "narrow" USD fork. Erik's had the best deal by far on these at $204 shipped for a pair.

On the wheels, I got to test ride a Specialized Fatboy with big, heavy, inner-tube boasting wheels. I loved the traction and cornering, but it just soaked up so much energy to get the thing going. Yes, I know that this part of the DNA of a fatbike... but I also was ever only interested in going carbon wheels because I truly believe you can feel a change of 250g in rotating mass. It's worth noting that the wheels on this build cost more than anything else.

Other points--oh yes the NASA thing.  I ordered mine in gloss white, and instead of adding or painting in graphics, I'm just going to put a couple NASA vinyl decals on it and theme it loosely around a Space Shuttle or Moon Rover. The space theme should go nicely with the Saturn V style fatness of the frame and carbon goodies sprinkled on the bike. We'll see if it turns out--if not, off they come.

The rest of the build is comprised of the best performance/value goodies I could afford (read: XT), and the only golden egg being the Raceface Turbine cranks which eBay helped out with. It isn't easy to find fat bike cranks+BB that fit a 197mm rear axle, are of any reasonable name brand, AND aren't $300.

Now, the wait! I'll keep you posted.

PS Big thanks to CMH on this forum--his info has been super helpful to me in the prep for this project.
