I used an RST sprite fork with the longest steerer available and had a buddy thread it on a lathe. I used 451 wheels with fmf powermoto brakes for the right ammount of adjustment. I thought about the Paul brakes but they were waaaaayy to expensive. Stay tuned for my 20s lil brother soon to be done for the wife sporting a SA 8 speed with drum brake (the new w version) and ACS nos z-rims with a nice soft set of 20 x 2.3? Big apples. Should be done in a week or so.

Very nice. I was just thinking about a IGH on my 20 that has sat now for several years. I noticed on Vancouver CL that the 20's are going for some crazy prizes.

I did all of the brazing myself using components purchased from gaerlan. A friend at work machined the v brake bosses to get the right fit. He made the stem from 1 solid piece of aluminum as well.

Candy-apple Red! Lovely. Love how you've put the brakes out of the way on the chainstays. Does that bracing horseshoe thingie improve rear braking much?

Correct me if I'm wrong. It looks like you started off using the linear brake adapter and then switched over to the brazed on bosses you were talking about. I'm doing the same thing as far as using the brake adaptor to fit linear pull brakes on mine. I'm trying to keep everything original except for the handlebars, brakes and wheels. But I don't want to touch the frame. I like the "old" look of the Raleigh green and the decals on it.

looks like thats just a brake booster plate on top of the v brake. as used on mtbs that had flexible frames.

Ive got a v brake adaptor plate with a shimano v brake on it. Its for sale, along with most of my stuff.

its thick chromed steel. so heavy. Ive seen alloy ones.

heres the shots of the custom stem. I know it must look ridiculously long but you can always cut off what you dont need. I'll probably leave it to give anyone riding it the most adjustment possible for a comfortable fit. It's a longer copy of the soma high rider made from one piece of aluminum

as promised I'm finally done with the 20 for the mrs. Please note the 8 speed drum hub bridges were removed and brazed back on after the frame was spread to 135mm. also the reinforcements and bottle bosses on the head tube, the mks ezy pedals, dahon biologic seatpost pump, straight chainline, 20x2.35 schwalbe big apples, suspension fork, old school acs nos z-rims, custom frame locking knob and ultra cool blue metallic flake paint. It's been a work in progress for some time and now that it's done here she is for your approval.
Well, it's not completly done i still need to get bottle brackets and shorten the cables a bit and........ lets face it, they're never really done are they?

I started off wanting to braze on the bosses. as Griftereck correctly pointed out that's just a v brake booster plate I added to help reduce flex in the chainstays. you never know when the metal will fatigue to failure especially on a 38 year old bike frame. You know the saying, an ounce of prevention is worth a pound of cure? Well i hope I prevented a stress crack later on. Besides, it looks kinda cool don't ya think?

No matter what you call it. It still looks like the linear brake adapter from Dimension. I just bought two of them. Now my next question is: What kind of clamp do you have on the headstem of the Missus's bike. Those bottle bosses you brazed on look sweet! Did you tap those out yourself ? You did a good job. I wish I had a torch kit.



What headset did you use?

The clamp is just an old 1 inch seatpost clamp with a qr added that the lbs had laying around. The headset is a ten dollar off the shelf 1 inch threaded style. The bottle bosses were bought from gearlan and brazed on using standard methods. The reinforcing rings at the ends of the headtube are hydraulic tubing that was bored slightly the brazed on using the same standard equipment. Brazing the bosses was quite a pain bacause of their size. I wrecked 2 sets before getting it right. Also the seat clamp requires substantial effort to close and I don't think the wife has strong enough hands to use it so i'm probably going to use the original clamp from my other twenty in it's place or make an L shape lever for this bike like the original using the stock factory seat lever. I'll make it work one way or another.

I sandblasted the frame and used Duplicolor metal flake for the red and blue bikes in this thread. The flakes were really bright so covered both bikes with Duplicolor metalcast (it's made to give an anodized look to shiny surfaces). It deepened up the colors to my liking, especially on the red bike. I then used several coats of acrylic clear laquer to finish it off. So far the finish seems durable enough. I guess a summer of use will tell for sure. The forks on the red bike were painted using duplicolors color shift paint but there isn't enough surface area to really see a good effect. Soon I will modify a bmx fork to use in it's place and either use VHT wrinkle black to go with the cages I just painted or color match it to the frame. One more thing, I tried a normal laquer before and it cures way too hard for a bike. Just a slight slip of a wrench nicked the frame badly. The acrylic seems much more durable. Hope this helps.

Thanks, ogeluv. I have a bike project I'm working on now and was thinking of using the duplicolor products. Both bikes look great,

Juan

might try a steel seat qr or a cut down steel wheel qr. steel ones have higher leverage than alloy ones
