Lugged single speed MTB?

[suhacycles]

Hey ya'll,

Has anyone here ever built a lugged single speed MTB? If so, what wheel size did you use? Got a photo?

Thanks,
Hansen

I made a lugged geared MTB 26" , see pic. SS wouldn't change much.

I am seriously working toward getting a lugset & shell produced specific for 29r.

Nice... Llewellyn lugs and LS BB I take it? Would be pretty cool to see a 29r lugset + shell but what about 650B? =D

Its Lewellyn's XLOS lugset and an LS mtb specific shell.

The slope of the top tube was increased, and the ht slackened (vs as the lugs were designed). Everything fits differently and the lugs took some blacksmithing. The bb shell took even more blacksmithing, as I don't think it was designed for a bike using a suspension fork.

When / if my 29r lugs become a reality, they'll be easily used in a 650b design too. :)

I would love for my next build to be a lugged 650b. Count me in for some MTB specific lug sets.

I've built a few. This one was Pacenti/Llewellyn Slant Six lugs. 26" wheels.

I'd ride the hell out of that, great work!

How is that 29er lugset coming along? Still working on it?

The tough part is investing the upfront $$ required to produce the casting mold tooling needed to make the four pieces (3 lugs + BB shell). Once these tools are in place at the casting house, things get simple & cheaper. The hurdle is that initial investment and the time needed to recover that investment selling one set at a time to curious dudes on vs. I don't mind investing the dough, I do mind it taking years just to recover my initial investment. So here we are.......

Until Glenn decides that he'd like to operate as a charity and get the pieces cast, you guys could consider making your own lugs. It's not all that hard to do.

HJ sells them, as does Everest.
Or make your own.

Gotcha, I'm sure it's not cheap. I just came across this thread and was curious as to the status. If you ever did get these produced I would certainly be interested!

I'm considering this. Just need to do a little more research on it. Basically you just miter some tubes and brass braze them together right? It's what to do next I'm confused about. Do you have to completely hollow out the inside of the lug? It's hard to explain, but can you just leave the unmitered part of the lug (the tube the headtube slides into, for example) intact; perhaps drill a gas relief hole in it? Or does the inside of the lug need to be completely hollowed out to allow the headtube and downtube to butt up against one another inside the lug? Did that make sense? I would think either way would result in a very strong joint. I know making lugs is a lot of work, and hollowing out the insides would explain why. That sounds like a lot of grinding but would be worth it when the frame is done. Not many custom lugged 29er's out there! I would love to build one.
