Singlespeed & Fixed Gear - Singlespeed Done

I posted it in MTB, but didn't know if everyone went in there :p Anyways...it was a beater thrown together, no fancy new parts, used a triple crankset I got dirt cheap.

nice job.

sweet. now get rid of those extra chainrings....

And post a pic of the actual drive train.

I digg it, and I'd also like to see more pics! :)

Do I see a U-brake? If so, that's the second one for the day in this forum! Yay!

Is it a Stumpjumper?

At least the first crash is out of the way.

Usually I would agree that you should try to ditch or grind down the extra rings, but in this case, I think they look kinda fresh.

I don't think I've ever seen brake bosses on the underside of the chainstays. That's hot.

How different do the two brakes feel? It can be difficult to set up a vbrake and non-vbrake combo. If you don't have them already get some brake levers that work for both cantis and vbrakes. Nice bike. I'm building a 1990 rockhopper and a SS currently.

maybe he wants the chainring to climb over logs?

or just as a cheap bash ring.

It looks like that could be the old-school roller-cam brake? I could be wrong and it might just be canti's mounted upside down. But now I am getting nostalgic...

This type of brake was popular in the early 90's on mtb bikes. I think it fell out of favor because, obviously, that location is subject to receiving a tremendous amount of mud. Also, the brake was hard to adjust.

The cam was actually a plate with a special curve on the edges and the brake levers had rollers that followed the profile of the cam. When you applied your brake, the cam would pull out, and the rollers followed the profile to actuate the brakes. The nice thing about it is that the profile allowed for drastic increase of mechanical advantage as a function of cam position (ie mechanical advantage increases as you squeeze the brake harder).

It was cool for a while, then canti's got more popular, followed by v-brakes and disks.

I think there are newer U brakes made for BMX bikes that will fit and have better braking.

Yay?! You weren't working in shops in the early nineties, were you? I hated those things.

Until, of course, you bash your leg into it.

I am about to do the same thing to my old Paramount MTB. How are you keeping the chain tight on that thing? What gear ratio? Are those American Classic Hubs?

It's a specialized stumpjumper rockhopper, something like that. The extra chainring will be grinded down and turned into a cheap bashguard, as far as the brake, below is a more detailed pic...the rear brake basically sucks ass. I love on my front brakes. then again, it could have been how I had my weight seated since I had no saddle. Oh well...here is a better pic, I think it is a U brake...Either way the brake looks odd :D

Hey, be nice. You know I think you're cool. (hair)

HAHAHAHAH yeah you took care of that for me!

The chain fits perfectly with a 32/17 ratio. I was going to go 32/15, but it just wasn't going to work. So that's how I'm keeping it tight :D I have no clue what hubs they are, feltup might chime in since it was his wheelset before mine.

Anyone want to take bets when the wheels explode? I say 3 days! ;)

Why would you say that? Are you just being an *******? I rebuild the hubs and trued and dished and tensioned the wheels. They are in great shape and will hold up well.

Dude, I'm sorry if I offended you. @ 450 LBS, he breaks things awfully quickly...
The stock wheels on his hoss broke rather quickly, and needed frequent truing...

Your rear brake sucks more ass than it needs to because its set up like crap. Granted I am sure that you don't have much experience setting up u brakes so its not your fault but still it could be set up a lot better, I mean just look at the straddle cable. Find a shop with a mechanic who rides bmx and have them dial in your U brake. I also would drop the dollars for a 990 or a Hombre with the Fiesta pack to replace that generic looking u brake, and maybe some better pads, like Odyssey 1x4's or Kool Stops. But otherwise that is a sweet looking bike. I found a nos DX bmx cassette hub laying around the shop I work that Im going to lace to a Sun Mammoth rim also randomly hanging on the back wall, now I just need a frame.

Actually these wheels felt pretty sturdy while pedalling around. Feltup did good, as far as that ubrake, no matter how it looks, it functions how it should, the pads set equal distances from the rim and work..it's just rim brakes have never really worked all to well for me. BTW...this bike will remain mechanic free...it's a SS project and it's gonna stay that way. The whole idea is to get by as cheaply as possible :D

BTW... here's Sheldon Brown's pics of the cantilever brake family:

hahahhhaha

It's true...I swear I should be a product tester for the "beefiest stuff" If it's supposed to be tough, gimme and let me ride it out :D

Tell me where I went wrong on the brake. I couldn't get the straddle cable even. Both pads are the same distance from the rim and they move well. It works a lot better than I thought it would.

Alot of it has to do with the spring tension being fine tuned and the straddle cable does matter; but mostly it is in how you tension the spings. I was just offering some advice as the it was specifically stated that the brakes were not to his liking. And I understand you are trying to keep it cheap but if you are really unhappy with the u brake spend the twenty bucks for an hombre with the fiesta kit, I am a big guy and those things can lock up the wheels on my flatland bike no problem.

I bet if I tinker with those bolts we twisted and set the tensions up I might be able to set the cable more evenly, but guess what, it works, haha I don't care. I have yet to see a rim brake that will lock up with me.
