Nice work. Looks like a pretty big lathe. What size and brand?

By high gear do you mean the largest cog? That is actually the low gear - lowest gear ratio with a given chain ring. I can't see what model of derailleur you have but it looks to be something like a GS cage Shimano. I'd need to know model number of the derailleur and the tooth count of your...

Yes. I have never drilled any rivets out of these frames but my guess is that they are aluminum rivets with aluminum shanks, which should drill out pretty easily. Problem with drilling out rivets is that the drill will often want to drift off the center of the rivet into the gap between the...

I have never checked the 1989 sloping SM900 Red Shred geometry to the later BOTE frames but the concept is clearly similar. Glad that you picked the bike up. The paint and 2.8 decals are still sticking points for me but that issue won't detract from it being a great bike.

Good to see. Hope they will be interested in reproducing more parts. The down tube shifter bosses for road frames would seem to be among the most in demand bits.

From what I can see, that should cover what you need to cable the frame. I haven't seen the stops you mentioned but derailleur cable tension and be pretty high. Back in the 1970s when everything was attached by clamps, frame builders used to braze a small piece of steel to the underside of the...

I never measured the stay diameter of an early Cannondale but my guess is that it's at least 20 mm so that clamp would be way too small. You could probably drill some holes in that stop and rivet it to the frame, but I wouldn't want to add more holes to the stays, especially if they were near...

Certainly something to consider. There are lots of options out there for vintage frames - all materials and brands. Don't know what your priorities are.

Kroil has a reputation as being the best penetrating oil but it's expensive and you usually can't find it locally. PB Blaster has a pretty good reputation and is easy to find. You can sometimes pick up framesets for less than the fork is worth so there is value there. These frames could be...

I was thinking that the 1987 frame I looked at had the two rivet holes (nearly) parallel with the rear wheel axle - in line at 90 degrees to the centerline of the stay. Those look to be staggered - kind of on a diagonal to the centerline of the stay. I have a couple of 1988 frames and some...

Maybe PM Improve Part. Was hoping he would get the parts in production because there aren't many options out there.

No special tools required, just a proper sized drill bit to drill out the rivets on the chainstay stop (start small). Adjustable wrench will remove the down tube bosses. Just be careful to loosen the correct side. The fixed side boss is diecast and pretty delicate. The one in my picture has...

All have the same decals and paint? Certainly could have been a limited or end of the year release that doesn't show in the catalogs but the 2.8 designation doesn't compute - especially since when the 2.8 frames did appear in 1995 they didn't have cantilever dropouts. I have a 1995 M900 that I...
