Double Oversize Sloped Top Tube lugs in Non-Polished Stainless Steel

Sloped Top Tube Lugs for Double Oversize frames.
The castings are well designed, beautiful, unique and very thin. Workmanship is top notch.

These lugs are for:

DT/HT : 35mm x 36mm and 60º
TT/HT :  31.8mm x 36mm x 79º
ST       :  31.8mm x 31.8mm x 79º

Here is Darrell's description of the lugs:


I wanted to use sloping top tube designs for reasons of structural merit, (less tube length, shorter tubes) and also to allow taller head tubes in frame designs for riders who need higher handle bars. The set required a 36mm head tube to fit 28.6mm (1 1/8”) alloy, carbon, or steel steerer forks and XL tube diameters that are suitable for heavy and or tall riders.

The angle of the top tube needed to be of the amount that was useful but not so much as to make the frame look like a BMX bike, I settled on 6 degrees of top tube slope. There needed to be lots of stack height on the top head lug that could be trimmed to suit the frame design. The bottom head lug needed to have cast bosses for M5 gear cable adjusters with a counter bore for the adjuster spring to nestle into, so when turned it did not scrape and chip the paint off, thus  helping to keep a neat and tidy appearance on the finished frame. A standard stainless steel M6 caphead bolt for the seat binder was a must have as well.

The seat post binder keyhole slot was to have rounded corners to avoid digging into and damaging carbon seat posts. I also needed to design enough room on the lugs for reshaping of the shorelines or extra elaboration if desired.

This lug set has been fantastic for my building (first in the Slant6, now used in the Crescendo model) saving me time and allowing me to create appropriate frames for particular riders or particular uses. These lugs are also in regular use with many builders around the world.
