I'm planning my next frame. I think I'd like to build a "trail bomber", something between a bike path bike and a mountain bike. If it goes off road, it would most likely be fairly smooth singletrack, but most likely, it'll have racks on it and get used for runs to the grocery store. I'd like to use an oversize tubeset, probably Kaisei 022. It'll definitely be cro-mo, no matter what.

Anyway, I'd like to build the frame with a sloping top tube for a 1 1/8" steerer tube. I checked out Ceeway and Nova, and nothing really jumped out at me as supporting a sloping top tube. Is there such a thing as a sloping top tube (6-10 degrees) lugset for oversized tubes? It can be a fairly simple lugset, medium to long point would be dandy.

I realize that this design would lend itself well to fillet brazing (or TIG), but this will be just my 2nd frame and I feel like I should master lug brazing before I take on fillet brazing.

Thanks,

Pete

Check Henry James.

I remember Hank had a bunch of OS mountain style lugs.

I'm not aware of a sloping single single oversize inch and an eighth steerer road lug set.

Since you went to ceeway I presume you saw Dazza's 6 degree sloping stuff.

To my knowledge that is about as close as you are going to get.

Why the desire for inch and an eighth steerer?

Dazza has double oversize w/ 1 1/8 steerer. They don't look that outlandishly big

Thanks... 1 1/8" steerer is standard for ATB, I'm probably going to put an aftermarket fork on it.

almost all steel mtb's are fillet brazed

Yeah, I know, but I feel like I should have better mastery (i.e. to the point where I have a level of confidence, i.e. 5-6 frames, not true mastery, which would probably be several dozen frames) over lugged construction before moving on to fillet brazing. Maybe I'll just build myself up a cheap grocery-getter frame instead with stamped lugs (that I can do some detailing work on, like shaping) and a basic Nova cro-mo tubeset.

if the shorelines don't meet one's approval then
the files come out.
I have them
