updates to the Frankencross:


Today we have the new Acera 28/38/48 replacing the old Specialized 22/32/42 set, new Odyssey Ghost pads on the u-brake, and GARY BARS WITH BAR ENDS. Yes, they do fit with room to spare, I dunno why so many of you think they don't. And I mounted my used set of pods, so the wedges are wider than normal from being tightened in larger diameter bars. I'm thinking about Retroshift levers eventually.

Comfortable, oh yes, but not ideal for all conditions. I thought my '87 High Sierra was brilliant at first, but I eventually decided it was a bit of a pig. I prefer the handling of my '90 Rockhopper, but the best advice I can give you is to try it and see for yourself.

I dig those CST tires, what model are those? What's the size, 26" x __"? I went to REI and looked at the WTB slicks again, I wasn't as impressed the second time around, so I'm still looking and your CSTs are the best I've seen.
Thanks again, peace!

^I can recommend the Serfas Drifter as a alternative, if you can't find the CSTs that is.

Thanks anixi! I just checked them out at the REI online store, those do look like ideal tires for my build. The tire has a great cut to the tread, it looks like it would hook up in the dirt and still roll smoothly on pavement. I'm curious since REI didn't list any specs, what is the suggested/max pressure on the tire?
Thanks for the suggestion!

For reference, I'm 155lb and with fat 2.3's I would run only 32psi off-road with 24mm wide rims, adding a couple psi for use with narrower rims.
On road, I would go up to 37psi, and wouldn't expect a squishy ride, but obviously not like a road bike either.

Hello everyone,
I've got a polish question... what are you using to shine up your vintage conversions? I'm curious about paint polish and metal polish. I've been using Zymol polymer polish for the paint for years and it's always done a great job. On my Cimarron conversion I've reached the stage of figuring out which cantilever brake calipers I plan to use with my Shimano STI brifters. Digging through the part bins I found an old set of first generation XT "Deerhead" (BR-MC-70) calipers but they were definitely looking their age! I grabbed my Simichrome and went to work...


Well, it was the magic luster I'd dreamed about but it did do a good job for an initial polishing, I think at least one more coat of Simichrome polish is in order. However, based on the funk and lacking any shine... the "Deerhead" XT canti calipers are now looking pretty good for being circa 1983-1986.
So, what's worked well for you guys?
Thanks!

Great deal! The Serfas are much more expensive, unless, as I did, you find a pair of them at the thrift store (NOS!) for $5!

Ok, so here's my latest project. Picked up this vintage BCA mountain bike this winter. It's a lugged frame with a biplane fork, cool fastback style stays, and laid back geometry (70/70). The paint is a little rough, but I like the color. Got the BB, headset, and wheel bearings done. The drivetrain is done, couldn't get the suntour accushift stem shifters to index with the accushift derailleur, but it works good in friction. Just have to do the brakes and tape and a few loose ends. Hope you like it.

Thanks for the comments guys. @Chris in Miami: The frame is not chromed. I cleaned the dirt off, used paint rubbing compound, then waxed the frame and the shine came back pretty well. The bike is from 1983 according to the codes on the dia compe brakes. The sticker on the top tube says "classic" which I assume is the model. I don't have too much info on the bike other than that.

Are inline cable adjusters necessary for proper cable tension or can you achieve just through adjusting the derailleur? For those using them, is there an optimum location for them?

not being a fan of indexing i've never really worried about it on shifter cables. for BRAKE cables though they are nice for adjusting brakes on the fly

Hi all
I have a 1993 full LX groupset with rapid fire shifters (7-speed). I just decided that my old rigid Balance XR-550 MTB rigid frame is in good enough nick to rebuild as a drop bar bike. So I stripped off the groupset and am now looking for an ideal donor frame. Any suggestions for a vintage frame that I should go seek out? Alternative is a new frame but prefer something classic as long as works well.
Thanks
Andy

When I first setup my mountain bike with brifters, I didn't have a barrel adjuster and I just couldn't get the front shifter to shift smoothly. After i got the inline adjuster in place for the front shifter, I was able to get the shifting to work MUCH smoother.

there are so many "acceptable" frames it's hard to say what to look for, especially since models change from year to year. At the minimum i'd find a frame with all Tange MTB tubes, stays, and fork. even better is Tange Prestige or True Temper OX tubing. or you can go with aluminum and/or composites if you're interested in that route
i also recommend a head tube angle on the steeper side but that's all down to preference

It's been ages since I posted at bikeforums, but I had to say that this is a beautiful looking build. I just acquired a near-pristine 1983 grey stumpjumper that I am thinking of setting up with drops as well. Your stumpy is very inspiring...Thanks for sharing!
