Richard Sachs hosts an on-line lug reference library, where I found these images of lugs I designed for the last really nice Allez built by Specialized in the early 90's. This was a ground up design, which included a fork crown, dropouts and a bottom bracket shell (later copied by Cinelli) all developed around a very refined lightweight tube set that used a proprietary 30mm downtube and chainstay profile. The lugs, BB & tube set were resurrected to build the red bike for the Oregon Manifest, although on that bike, the lugs were highly modified, removing the direct fit sockets and filing them extensively.
Check out Richard's site for a historical look at the kind of choice we once had in lugs:

Those are very beautiful lugs, Sir. I knew it wasn't Giant lugs, even though they built the Allez for Specialized. No way Giant could come up with lugs this beautiful. BTW, what was the wall thickness of those tubing. Were they heat treated? I had a 54cm early 90's Allez and the frame weighted just under 4 lbs. That's about 1/2 lb lighter than a Tange2 or 531c. Your bikes look fantastic!!!
ReplyDeleteI have one of those Allez, which I love. At 200 lbs., currently, and given the age of the bike, I am starting to worry about the Direct Drive aluminum fork. Trying to puzzle out a carbon (found 1" threaded at a good price) vs. Torelli steel fork. Is 43mm rake okay? Thanks for any thoughts you may be willing to share!
ReplyDeleteHi Albert, and thanks for the kind words. the tubes were 8 5 8 tt and dt, 8 6 st, 8 cs, 6 ss. they were not heat treated. probably Fuji Shaft 4130 which was drawn to fairly hard. i did the dropouts and probably all of the details, can't remember everything.
ReplyDeletenoblet1, your fork is probably just fine if it still has a good coat of paint. all of the stuff that i worked on at giant was thoroughly tested. i would think 43 would be ok if the frame is 54 or larger.
