Thanks for that extra pic. Your help with the disassembly and then later facilitating the Phil rebuild was most appreciated!

I'm still working through a couple of parts issues/choices, but here's what the build spec is looking like: FRAME: Potts Brazed MTB #SP 11-83 052 [a] FORK: Potts Type-II [a] HEADSET: Specialized Channel-Lock 1" Silver [b] STEM: Potts Flat Bar for Stubby [a] HANDLEBAR: Potts Flat...

Slow but steady progress. The Phil Wood hubs (see the "before" pic a few posts up) got disassembled and a long soak in the amazing Evapo-Rust stuff. Rust is gone but now, but obviously the pitting it caused remains. Next step was to send them off to Phil for a "rebuild" (meaning...

It's the (filled-in) extra hole on the top surface of the left brake lever perch. It was the mounting point for a Suntour Mighty shifter. Here's a pic of the WTB modified shifter mount on another bike. There's also a sort of complete explanation of the parts and mod with more pics on the...

1983 was still very early-days for WTB. They weren’t making that many different parts at the time. The bike came with and will retain: - WTB Rollercam brakes (front and rear) - WTB Steel Flat Bars (24” wide, 25-deg bend) Not on the bike when I got it, but almost certainly there...

M900 cranks are 5-bolt, 110/74 B.C.D. On a 74mm BCD, the smallest ring you'd be able to fit is a 24t. See: http://sheldonbrown.com/cribsheet-bcd.html As for where to find chainrings, are you looking for genuine, period-correct Shimano rings? If so, you should look on eBay or similar and be...

Someday it too will get built (and have a build thread). :wink:

Well, it's not a boat anchor --- but probably at the heavy end of the spectrum. Another data point: 1986 Steve Potts Brazed "Racer" frame. 18.5" (but with a slightly sloping and longer top tube than the '83, it's probably the equivalent of about a 20"). This white one was ridden for a full...

Update: The Tear-Down Given this bike’s (rough) condition, it obviously needs every last part assessed for usability and, at a minimum, a thorough cleaning. That means stripping the bike down completely. The previous owner had noted that the seatpost was stuck. Not just stuck, but...

700c wheels/tires?

There IS a lot of “story” to this one. I’ll share some of it here publicly... and perhaps a bit more as the project moves forward. The bike was commissioned in 1983 by a local Marin County rider of some note. It was his first “10-speed” (his words)... as all his earlier bikes had been...

I’ve seen that... As well as Jeff Archer’s MOMBAT timeline and various catalog and spec pages ( http://mombat.org/MOMBAT/history.html ). I think the Speedplay site is wrong on this one. If you look at all the early MTB specs, most were using Suntour BMX (MP-1000) or MKS BM-7’s. Folks with...

Non-original items on the bike (as best I can tell/speculate): - Rear rim (Mavic; Front is probably original Araya 7X) - Front Derailleur (Shimano M700 Deerhead with ’84 date code; Signs of early band-type FD in the paint) - Rear Derailleur (Suntour XC Comp with ’89 date code) - Pedals...

New project. Should be an exercise in restraint... I hope.

Buying and collecting cool bikes that don't fit is fine. It's only when you pretend they actually fit you that it's a problem. 8)

Owners trying too hard to make a size S or M frame work for their size L or XL bodies.

Behold!... The Burnsingham. ;p

I think "bling" is a misleading term too -- as it's probably too associated with the color-anodized parts (i.e., not silver or black). It leads to a perception that in the 80's there weren't upgrades or high-quality aftermarket parts available. Nothing could be further from the truth. I...

Well, it starts out with a very high note. What site or publication did this contest/event? Link?
