Monochrome Motocross

[Pondo]

For anyone who may not know... 12G spokes are a huge pain in the aas, and rare enough to make them expensive. I've been waiting for WEEKS on a solution to some issues we've been having (basically, non-confidence in measurements). So... I just got off the phone with the spoke builder. I'm toss the 12G hubs to the side, get 14G hubs, re-measure, cut & roll the 14G, then get them here. @Pondo and two other guys are waiting for their wheels from me, and this has taken way too long.

Frustrating!!

No worries, man, I'm in no rush. I'm just looking forward to seeing how your builds are going to turn out!

I recently bought 12g spokes from an eBay seller. Velorepair. Definitely more expensive than 14g, but they were cut to length and shipped fast.

I'm honestly tired of waiting. 3 builds waiting on wheels

I didn’t take a picture, but the elongated Murray drops were all bent up. So worked on straightening and spacing.

This frame was spaced for 5-speed I think.

so I wanted to sqeeuze it together a bit.

Then I brake out my homemade dropout alignment tools and got the dropouts set.

Spokes arrived today. Laced the wheels. I’ll tension and true them, get in the tires, and start mocking up the bike.

Diggin' the gnarly tires!

@outskirtscustoms threw me a set of plastic fenders to try out. I could make the front one work, but the rear one comes up pretty short, and I think some sort of fabricated extension would look silly. I’ve got one more thing to try for fenders before I just go fenderless.

Maybe add just a little chunk of metal from an erector set and a few bolts?

So I got these a while back. They are just flat pieces of plastic. But the black with white stripes fit the theme, so I gave it a $25 try.

Obviously they sit very flat on the bike. So I broke out the heat gun and held them in place with zip ties and proceeded to soften them up.

Here’s the results. I can’t say I’m in love with it. They don’t really flow with the tire diameter.

You could try again but use the tire to get a nice radius.

you could try again….
on some other bike at some other time in some other place.

I like the maroon ones. And perhaps the rear could stand to have an aluminum top strut laying on it that comes to a radiused point maybe halfway down it's length with speed holes in it. Speed holes that keep getting smaller toward the tip. Sorry for my vague description. A picture would be better.

I get it. Your description was detailed enough. But fabrication would be my obstacle with that. I’ll have to mull on it.

or zip tie them to red fenders. then use the heat gun. to re shape them more curved and round.

Current snag: was installing seat post and it doesn’t fit. It starts in, and gets stuck right here.

So I’m guessing the only way I can get it past whatever lip is holding it at that point is by smoothing down the internal metal.

Unless you have a better idea?

 

[RustyGold]

I'd say since the slot is V-ing...the post is too big.

 

[OddJob]

Yep, looks like the post is not the right diameter from the way the seat tube is flanging out at the top.

 

[Pondo]

I like these fenders.

And I like this idea, though it's a bit of work.

I also think it would look cool with and early Schwinn style MX bar that looks like apes with a cross bar. And an early MX style seat.

Fenderless would be cool too. Looking forward to seeing where it winds up!

To me it looks like the bottom of the slot has been crushed in a bit so it's undersized, but I also wonder if the post isn't a touch oversized?

I'd measure the OD of the tube well below of where it's been clamped, then measure the thickness of the tubing to do something of a reality check. If it's close to the size of a stem I might try using the stem's wedge to move the material at the start of the slot. If you position the wedge opposite the slot, the shape of the stem should make the tube a bit more round at the slot?

Just an idea based on a quick look at one photo...

When I was working at a bike shop, some kid starting forcing an oversized post into a tube. It expanded the tube where the sot was, and then when it "bottomed out" on the start of the slot, it just started cutting the tube, essentially just making the slot longer. The dipschmidt just kept WAILING on the post with a hammer, cutting the slot deeper. He was not a master mechanic...
