Sidewinder V19 Single-Side Chainstay Yoke Offset 1.5″ Miter (4130 Steel)

*Same as V9, but with a 6mm offset miter at the bottom bracket. This shifts the drive side chainstay down, creating more welding access at the BB between the seat tube and the yoke. This is intended for use on the Drive Side. We do not make a mirror image of this part for use on the non-drive side.

Intended for short-chainstay, fat-tire, boost crankset 29r bikes, the sidewinder will make your build go a whole lot easier.

• BB Pre-Miter for 1.5” OD BB Shell

• Chainstay boss is 17.1mm OD for use with a .75”/19mm round chainstay

• 105 Grams

• Machined from 4130

• Designed around a maximum 36t boost chainring

• Designed around a 2.6” 29r tire at 415mm CS length, but there are multiple variables at play here so you have to do your own calculations and confirmations for your use case

• 2.8” at 420mm should work well also, but again, you have to do your own engineering for your use case

• The pinch-point between the chainring and tire is 6.5mm
