Parts Pile

Some of the recent pile of parts I’ve collected. Time to build.

So, let me get BMX-geeky for a minute here.

Those chrome forks leaning against the front of that Dyno frame and forks are special. In the early 90s, BMX frames slowly started switching from 1″ threaded headsets to 1 1/8″ threadless ones or “Aheadsets.”

Around the same time, Dia-Compe 990s (and other “U-brakes”) became standard. These brakes require mounting posts welded onto frames (on chain or seat stays) and forks as opposed to just a hole drilled in the middle.

Also around the same time, people started running 14mm axles as opposed to 3/8″ ones, the former of which require the slots in frame and fork dropouts to be wider to accommodate the larger axles.

I say all of that to say that I found a pair of GT forks — the ones in the photo above — that have a 1″ threaded steerer tube, 990 brake mounts, and 3/8″ dropouts! Woo hoo!

Thanks to Sandy, Taj, and eBay for continued support of my odd bike-part demands.
