London Fixed-gear and Single-speed

The rims seemed to have grown more than the tyres (BFL aside). All the latest fatbike tyres use pretty much the same carcass, as those endo's (apart from origin 8). Rims are now availible in all sorts of widths.

I saw a pic of the knarley Nate tyre mounted on a 100mm rim. Looked positivlely menacing.

I based alot of my geo on the pugs. For all the modern Ti, hydroformed alu etc frames availible now. The pugs is still a little special.

Looks like I've sourced my fork :D

NOS 2007 lefty max shell,
2012 PBR damper installed,
Travel reduced from 140 to 110 (for fat tyres)*
custom clamps (for clearance)
1 1/8" steerer




(My hope is to drop the forks 10mm in the clamps, so could win back 10mm travel, and run 120mm. We'll see).

Make sure it's travel 'limited' though, not just reduced or there may be some sparks when those studs meet the crown! :]

Could be a good winter lighting effect ;)

Yeah its limited.

I'm still a little unsure about having the frame built around a 480mm fork TBH. With 40mm sag the fork will naturaly sit at an effective 470mm. I'll be moving the leg down 10mm to hit the 480mm. Also the Enabler I'd like to use for winter/trekking purposes is 470mm long. So 470mm sounds neater.

So in summer sus mode I'll have a 70.5 deg head tube angle, and a 60mm BB drop.
Then in winter rigid mode I'll have 70,9 deg of head tube, and 63mm BB drop. (all a big guess)

In my head, these set-ups sound spot on. But everything is a mass of theory right now. Its stressing me a tad.

Also I should own up to the fact that I want to drop the fork in the clamps, partly because its looks naff with the top of the fork poking out too far.

Uhoh, I have some 170/135mm hubs in the post to me. It's the start of something.

Ha, you're too easy Gabes.

Which ones?

Salsa rear, surly front.

Just been reading more about On-one's upcoming offering, looks like you've been having some fun discussing IGHs with the Shiggy and Shaggy.

Just remember that the front hub has rear disc spacing, so needs a fork with a rear spaced caliper mount.
...or you can use those disc mounted cog spacers Velosolo sell, to space the disc out.
I did suggest a combination of the mukluks 35mm spacers (for converting a 170mm rear end to 135mm offset), and on-ones own swap-out system.

2 non-drive side drop-outs, one effectively being a 35mm spacer.
2 drive side drop-out, one being SS/IGH compatible.

Also discussed TT shifter location on a Jones bar, and its effect on your dental health. Might be valuble advise there.

I shelved idea of a fat bike a long time ago.
You two bastards are making me want one again.

Its certainly fueling my already bad tyre lust.

A set of these combined with 120mm of travel up front, and a slackish set-up = Downhill fun ;)

Background on the fork I've gone with.

Craig has been a star during our email correspondance. Could'nt recommend him enough.

Thanks Lee, yeah, I'm going with a mukluk f&f. so the enabler expect rear spaced.

I also got in touch with Carbon Cycles (who make cheap carbon forks for lots of other people, including the White Fat bike carbon forks) and they will start selling 135mm spaced forks, exactly the same as the white ones, later this year, and I have a pair of their 100mm ones already, they were £80!

Basically, this: (I'm going to get it painted too, but not sure of colours yet)

It looks cool- where are you intending on using it Gabes?

In the cuntry (sic)...

Saw that build on MTBR. Such a nice working of the Mukluk. The enable fork looks nice. Stainless drop-outs and everything cage mounts. The stack of the mukluk is a touch too much for me though.

Carver do some nice carbon forks. You can get them from Bikeman.com. From the US though.

I'm moving to devon this summer, Beaches, moors, forests, whatever really. It will be fun.

My eyes have just gone green

I'm from devon. Dartmoor is full of marsh lands that a Surly Nate tyre would love.

The fat tyres create far less trail errosion too.

.

Gabe: Cyclocross bikes are shit. Get a real off-road bike.

Cx bikes are great for the right trails. Too soft, and they sink, too rocky and they bounce around losing traction.

Mine works great on maintained mountain paths. Off the path, and even my 2.55" tyred 29er bogs down.

Solved it you.
Fat trials bike ;)

I might have ordered most of a fat bike. No rims in stock until end of march though :(

This is a mad offer. These rims get mixed reviews, but mine seem OK. The bead lock is a bit shit so you need plenty of TLC to seat the tyre properly. Definitly worth drilling them to save weight.

Also. I've just ordered some CB Mallets. Should be able to ride with my Sorels on, when its really cold. I have some Artic northwaves coming for milder winter contions.

Can you hurry up with the build as this is the bike i am most looking forward to seeing this year!

^This.

Still waiting on tech drawings of the frame. The builder has had some data issues, and to be honest I owe him some breathing space after being such a tricky customer.

Then its just brakes, stem, saddle, seatpost, and rear hub, to source.

Still have to figure out what to do about rear mech adjustment. The X-0 mech has no adjuster, and neither has the TT lever. Plus, I'm not sure about insalling an in-line barrel adjuster with Gore sealed cables.

Also just to put my build in place. This guy built his own frame (he's done a couple now) from Bamboo, alu, and carbon. In his garage.

Hub geared, fatty tyred, drop bared, fat lefty, with bamboo frame. Amazing.

and belt drive!

Wow, wow, just... wow!

What brakes are you going for Lee?

I've gone for BB7s, and I found a crazy cheap deal from an eBay selling on Hong Kong, I have bought from him before too, delivery was fast.

Pair of BB7 calipers, rotors, and Single Digit 7 Levers: £69.99 http://bit.ly/ydPcgn

Had my eyes on som M4s. Rarely cycle at under -15C so I dont think the DOT fluid would struggle. IMO you'd have more issues with ice build up cycling in our climate. Which will feck with any brake system.

Also. Just ordered a meaty looking inline cable adjuster. Hopefully I'll be able to get my gore cable liner through it.

Lee, I just got some Atlas FR cranks from wiggle, I'm pretty sure they have sent me the wrong ones (normal axle length) I haven't ordered anything from wiggle in years, as they are fucking useless, but they said they had these in stock in black for 100mm shell.

Could you measure the axle of yours?

Thanks!

Mine are hidden from Mrs Smallfurry, in my office, at work. So that would need to be Monday. Bought mine on clearance from CRC.

I have an extra BB I picked up off EBay on a wim, if you need one.

Just realised my SRAM TT level wont fit into my cut-H bar end. So have ordered some Paul thumbies. I will have to rethink my bar set-up. But the cable routing will at least be better.

....and yes wiggle are frequently a PITA.

No worries, I'm returning them. Useless fucks.

Even the returns process is like pulling teeth.

I think these bikes would probably work well on Dartmoor. There are hundreds of miles of bridle paths that are very, very hard work on a 29er with 2.3" tyres (for example). Once you're out in the open the moor's paths are mossy and grassy peat basically and often waterlogged.

Not sure how well they'd ride off the moors where it's muddy and there's clay in the soil.

That really is quite something.

miro_o:

Yes, dartmoor should be great, I used to ride there a lot as a teenager, it was brutal on 26x1.9" rigid forks. The fatties should make it more fun!

A lot of devon is clay-soil, but it's not the most sticky variety, at least not around where i'll be living. I'm also hoping to do a fair bit of beach riding. I'm interested to see how well they cope with pebbled beaches?

You forgot "belt drive".

You forgot to read the rest of the posts. Lose.

The RaceFace is the nicest option you can easily get hold of in the UK IMHO. There is the option of going with some square taper/Isis cranks (middleburn). But I like external BBs.

The new Factback double looks nice.

FTR I've been following every step of that bamboo build, and simply forgot to list the belt drive (seems so ordinary to me ;) ).
