I need also a 27,2mm seatpost one for 95 Altitude, so the same. And same ext ID theoretically.
New order, new colors!! Redesign Rocky Mountain tilted seat clamp.
- Thread starter Fatboy1974
- Start date
A fast checking:
93: Tibolt (Ti) 27,2 mm seatpost
Altitude (Cr) 27,2 mm seatpost
94: Tibolt (Ti) 26.8 mm seatpost
Altitude (Cr) 27,2 mm seatpost
Vertex (AL) 26.8 mm
The Edge (AL) 26.8 mm
Blizzard (Cr) 27.2 mm
95: Suzi Q (Al) 26,8mm?
Altitude and Altitude TO (Cr) 27,2 mm seatpost
Vertex and Vertex TO(AL) 26.8 mm
The Edge (AL) 26.8 mm
Blizzard (Cr) 27.2 mm
Seems that all Seatclamps should be same dimension. I see that alu bikes has 26.8mm, usually because Alu tubes are thicker, so external id should be similar to their Steel sisters. Anybody can check the external ID of their bikes in that models (93 to 95)?
From 96 in advance they understood that it was a bad idea so all Seatclamps are straight.

So the only two OD would be 28.6 and 31.8? - I'd be looking for 31.8 for my 95 Vertex and 95 Thin Air.

Really? That’s so odd, were they cut straight? Not to derail, but what colours are yours? Can you DM me I have questions.
In catalog 1995 vertex is angled, thin air straight.

I see that, but IRL my 95 Thin Air is angled. These are reasons I love early Canadian made Rocky Mountain's, nothing makes sense, and seemingly no two are identical.
I'm thinking in this redesign. 18-20mm thick instead of 12mm, but then machined to appear light . so it's better braced. But I want to make it better and I'll take some time to make it less fatty! But I will priorize strenght. New vs old

I don't agree. There is abigger cylindrical area effectively working in the perpendicular plane. But ill refine and ill do a finite element analysis.
