Ripmo AF Specific FAQs

All our manuals are available here. You can also find the Quick Setup guide for the Ripmo AF in the 'Setup' tab on the right.

You can find all our torque specs listed in the tab on the right. The Ripmo AF and Ripmo use the same torque specs.

We spec and recommend the DVO Jade X Coil shock, but you could run any clevis compatible coil shock. Brands that offer a clevis compatible coil shock include DVO, Cane Creek, EXT, Push, and Rockshox. We recommend verifying clevis compatibility with manufacturers before purchase.

Check out this video for instructions on how to swap the forks spring. The bike ships with a medium spring installed across all sizes. This spring is good for 150-180 lbs riders. Below are the appropriate part numbers for replacement springs:

  • 120-150 lbs, Purple, Soft, 820-03-656-KIT
  • 150-180 lbs, Blue, Medium, 820-03-657-KIT (Stock Configuration)
  • 180-210 lbs, Green, Firm, 820-03-658-KIT
  • 210-250 lbs, Yellow, X-Firm, 820-03-659-KIT

No, we designed the Ripmo AF specifically around 29” wheels.

The largest chainring the Ripmo AF can accommodate is a 34T.

Yes, the max size oval chainring we recommend is a 32T. Not all oval chainrings are the same, we recommend double checking clearance before installation.

The Ripmo AF is designed to accommodate tires up to 2.6” wide.

Swapping the coil spring in the Bomber Z1 is a quick and easy job, check out our guide here.

Yes, but the bike is optimized around a 44mm. The 51mm offset fork shortens the trail (the distance between the contact patch and the steering axis), which can cause the front end to feel less stable.

170mm crank on small and medium.

175mm crank on large and extra large.

40mm stem on small.

50mm stem on medium, large and extra large.

No. 160mm is the maximum allowable fork travel.

Our engineers determined that gusset wasn't needed, so we stopped welding them on after the first batch of frames (the ones that were used for photography).

The Ripmo AF fits 22 oz Purist water bottles on all sizes when the Arundel side loader cage is used.

The Ripmo AF uses 160mm post mount rear brake mounts.

To run a 180mm rotor, you'll use the following Shimano part number: SM-MA-F180P / P2
To run a 203mm rotor, you'll use the following Shimano part number: SM-MA-F203P / P

Dropper Post Saddle Height Calculations

Do not try to insert your post deeper than these measurements. Forcing the post can result in a seat tube failure.

IMPORTANT: Before riding, check the saddle to tire clearance with the dropper post fully dropped and the air out of the shock with frame compressed to bottom out. Small and Medium minimums are controlled by tire bottom out.
