  1. Front triangle cluster, seat tube cluster, rear stays, all in stainless steel (or titanium) awaiting their carbon tubes. Carbon tubes shall be:top tube, seat tube, seat stays, chain stays, and down tube…But where is the BB?

  2. It is the titanium lugs for a bike made by Specialized in 1994(?) that had carbon tubes coupled with these titanium lugs and was called the “Ultimate”
    I’m pretty sure anyways…

  3. mmm… I’m was going to say it’s the lug set for one of the Trek bonded carbon fiber bikes of the early/mid 90s. these would have been aluminum, though, and it was a fastback seat cluster… the weird thing is that the brake bridge isn’t drilled. that and the head tube is complete. most – especially early versions had a CF head tube…


  4. The seat cluster doesn’t look right for the Specialized Epic Ultimate. It looks as if it has been chopped in half to produce the seat cluster and seatstay bridge separately . If you look at the pictures that Andy posted, you can see what I mean.

  5. Lugs thats for sure. Most likely made to interface with some carbon tubing. And from the color of the heat effected zone I’m going with Ti.

  6. I think a few of you are missing the fact that the Cantis don’t mount to the bridge, they were set up on their own metal sleeves. Look at the images in the link posted by NoCoRider, and you will see what I mean. The canti sleeves and BB are just not pictures in the post here.

What do you think?
