Top tube downslope angle

Who said anything about bog standard tubes?

i did :-)
who is the builder then?
plain gauge? butted? multi shaped? different tubes for different sizes (like serotta)

Front triangle butted; rear triangle plain gauge. Downtube is going to be shaped for stifness.

Iain Roche is the engineer/designer (one of the two brothers behind Sabbath Bikes). It will be built in China. Stops it being prohibitively expensive.

i would trust the designer, but ask if there would be any issue with a less severe angle and go with what they say.
sounds like it's going to be a nice frame.

One of the reasons Dave Yates gave me for not building a frame with a very shallow angle on the TT was cos 'it would look like a mistake'!

Sabbath - very nice. I recently found out they build Shanaze Reades Ti BMX's.

it's fucking fine. Anti-compact geo people are cretins*.

*Thanks for my new favourite word, Object.

Yes. Fucking yes.

Gentlemen, to the gelateria!

The geometry I worked out for a possible XACD roadie, had a 8 degree slope. This was pretty much as high as I could go without breaking the all important seattube cluster above rear tyre rule.

ETT . . . . 535mm
HT . . . . 121mm
ST (C-C) . . . 460mm
ST (C-T) . . . 609mm
CS . . . . 403mm
BB Drop . . . 74mm
HTA . . . . 73,0º
STA . . . . 74,0º
TT Slope . . . 8,0 º
Saddle height . . . 695mm*

i totally agree with this. I was mainly speaking my my persepctive which is at least a 56cm frame. But yes i agree completely with this aesthetic point.
