I've entered the realm of near-insanity.
The chainring combination of 26/30 isn't available anywhere by anyone (except companies with crazy drilled modular spiders).
So I made my own.
I found that Race Face makes a nice 26 tooth ring in 74 BCD and it has tabs inside the stock bolt holes, possibly for drilling to 58 BCD, also possible to keep the chain out of the gutter between the BB shell and the crank.
So I got one of these which is hard anodized 4mm aluminum, then took an old ring, matched up where the holes should be, clamped the two together and drilled out the new bolt holes. I had to do a little hand fitting with a rat tail file but it is super snug and I'm expecting it to hold really well. If it cracks, I'll have a custom one made out of stainless steel. I have a Surly 30 tooth stainless ring. It's a shame because Surly used to make a 56/58 BCD multi-mount ring out of stainless but they were discontinued over 10 years ago.
Here's the crank:
After that, I did some more jumping on the Raleigh Mtn Trials frame to get it straight and got the rear triangle within 1.5mm. That's less than the amount of tire knob deflection one can expect, so it's close enough I think.
Being impatient, I wanted to see if I had the right bottom bracket and installed the crankset on a Tange BB I have here. I also stuck the Suntour freewheel on the White Eno hub and got that mounted to check the chainline. The chainline is about 2mm off by my eyeball and calipers, but I haven't done any real measurements or math, so I'll get there. It's only a matter of a 1mm spacer, either at the bottom bracket or at the freewheel to bring it perfectly straight.
I'll be pulling all the parts back off the frame, then painting the chips with the near-matched enamel I got from Sherwin Williams long ago. I'll look like a patched up rat bike with a candy apple red fork, but it's going to be cool. Come to think of it, I may do a bit of a custom paint job on the head tube and stem with some red paint to match the fork, we'll see how motivated I am to do all that.
Thanks for the praise on the Breezer, Cal. I'll give credit to Joe Breeze for that one. While I like stainless steel hardware, I might change a few bolts out for titanium to see if I can drop a pound. Crank bolts, all the M5 bolts, handlebar clamp M6 bolts, titanium skewers and seat clamp. That's all probably a pound there. A lot of weight is in the wheels with the RhynoLites and wire bead tires. I'll just enjoy riding it for now before I become a weight weenie.
