Some developments

I recently picked up this little gem, it's in pretty amazing condition and was obviously rarely ridden. I got the bike from a really nice guy who had a long history of involvement in Bay Area bike stuff. It turned out that he had run a foundry that had made fork crowns for early Ritcheys and even had a few knocking around in boxes. I should have snapped a cell phone pic... Anyway it was neat to meet someone who knew a bunch and had some good stories to tell.

1983 Ridgerunner (as best I can date, I don't understand DB's serial #s but parts are correct for that year) This bike was supposed to be real competition for the Stumpjumper. The whole build includes some of the best parts available at the time. I took a lot of pics just to document the original condition before some changes are made to make it a more practical bike.
It came to e with these tires, unoriginal I was told, but I love these old basic tread patterns. These have a pretty heavy rolling resistance.
Front and rear cartridge bearing Suzue hubs. Unfortunately it's got chromed spokes, looking a bit funky.
Great fork with the mid fork braze on.
Kind of funny finishing on the fork crown, lots of casting texture on the middle of the crown and crusty edges.
Fakey Nervex lugs too, which I'm pumped on. These are a bit smarter than the Stumpjumper as the undersides are a bit more rounded.

I love these old Dia Compe yoke rollers. Who else made a roller other than Rene Herse?

This bent bullmoose was specific to DB
A pleasing detail on the stem cap.

So many nice details

I always say it but I love those super long stays.
All the good stuff from the era.
The Mountech rear ders are lousy, but the fronts are pretty cool, even campyish

The Superbe Tech rear der, so weird, so awesome, but such a crappy derailleur...The guy who I got the bike from commented on the bad shifting and he was right on; this set up is one of the slowest clunkiest shifts I've felt in a long time.
This bike was optimized for this der. Check the cable stop!

Just a better drop out shot

The Centurian Anatomic, looks a little like the bananatomic...
A camera fits where my head won't.

Ok well on a different note, I decided to replace my rear wheel on my Stumpy. The IRD 5 speed freewheel turned out to be a real piece of bummer; probably only a few hundred miles on it and the pawls were not engaging properly. The only other options are cheapo Shimano ones that tend to have a limited range. So I decided to build up this old 8 speed 600 hub with a Sun Rhynolite rim. I chose a road hub because the Stumpy is spaced 126 and I'm hoping that the 4mm more on the road hub will be a work around for a re-spacing.
Also there is this book I got in France. Great cover shot!
Not too much of note inside (that I can read) but I liked this Passoni ti number. Is that a drilled to hell Brooks?
Also, some random french (Japanese) Stumpjumer knock off.
Lastly, a recent pick of my Ridgerunner with it's new knobbies. The rear is a 2.4 and the front is sadly a 2.2 as the replacement fork would only handle a small guy. This set up works great and feels rowdy in the dirt.


  1. Where'd you get your replacement fork? I've been trying to find one for my '90 Trek 950 (the fork on it right now is not the original, so the steerer is a little too short) but haven't had any luck sourcing a decent 1" threaded fork.

    1. Finding threaded replacement forks isn't easy! Mine came from a destroyed 90's trek commuter bike. The good news is you can order brand spanking new ones if you can't find a suitable used one. Sunlite and Dimension both make them with different lengths and they are easy to find on the web.

    2. Thanks for the tip. I think I will go with the Dimension fork and have my local frame builder put a few bosses in the blades. (finding a fork with bosses is even harder!)
