Description
The S&M Mad Dog is Chris "Mad Dog" Moeller's signature frame, reissued 36 years after the original. It is a sub-5 lb, made in USA frame with a 10" standover and an IS disc mount, offered in seven top tube lengths from 20.5" to 22" and four colors: Challenger Red, Gloss Black, Holmes Yellow and OG Green.
Features
- 4.9 lb frame weight with disc brake mount
- IS-mount disc tab for 120mm rotors with a 0mm IS-to-post adapter, or 140mm rotors with a 20mm adapter
- Works with hydraulic or mechanical disc systems; narrow-flange hubs recommended for spoke-to-caliper clearance
- Tall 10" standover for manuals and aggressive body positioning
- Traditional 110mm rear spacing with 3/8" dropouts, so no disc-specific wheels needed
- Slotted seat tube for a traditional or quick-release 28.6mm clamp
- Engraved Shield on the head tube, engraved '87' on the bottom bracket shell and Mad Dog tag on the seat tube, so the graphics won't wear off
