Over our long tenure from mountain biking’s awkward adolescence to its current anything-shreddy era, we’ve experimented with steel, aluminum and titanium—remember the Bow-Ti, the first superbike? We remember the metal times too, and it feels good to offer a premium ride experience to our broadening family of riders, courtesy of durable, affordable aluminum alloy.
The Ripmo AF UDH features a UDH derailleur for maximum future compatibility and moves to a 55mm chain line. The wider chain line allows for a stiffer chainstay.
With a steep, 76-degree seat tube angle and a rangy but not stratospheric reach, the Ripmo AF places riders centrally and upright over the bottom bracket. It makes for an efficient position that can go the long haul without placing too much weight on its slack, 64.9-degree headtube angle. A 44mm reduced-offset fork is more surefooted on steep descents and steadies high speeds. Better up, better down.
Since 2005, we’ve partnered with suspension guru Dave Weagle on the dw-link suspension platform. It provides an unparalleled combination of climbing efficiency and downhill performance, which has been proven repeatedly at the highest levels of racing.
The Ripmo AF is compatible with both coil and air shocks due to a more progressive leverage rate. It allows for coil’s linearity to thrive and we spec air shocks with tunes that provide pop without feeling too harsh. On the trail, it gives the suspension a supple feel throughout the entirety of the stroke, enhancing traction no matter how deep you dig.
Ibis helped pioneer the wide rim revolution, which inspired the new crop of wider 2.4” — 2.6” tires. When paired together, this combo can be run at ultra low pressures which results in elbow-dragging cornering traction without sacrificing straight line speed.
We use words like small, medium, and large to describe our sizing because it’s easy to understand, but our ultra low standovers give you the ability to size your frame based on reach and preference.
What’s better than a dropper post? A longer one. Our frames are designed to accommodate the longest dropper posts possible. Riders over 5’8 (or 173cm) can easily run a 185mm dropper post, while folks between 5’ and 5’8 (152cm - 172cm) can use a post 125mm or longer depending on inseam length.
Our optional ISCG 05 mount is there if you want it, removable if you don’t.
If it’s our fault, we’ll fix it. Simple as that.

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 has clearance for the majority of 2.5" tires. However, we cannot guarantee fitment of all tires. There's too much variation between manufacturer's measurements. We recommend installing your preferred tire without sealant. Release air from the rear shock and while cycling the bike through its travel, please ensure there is a minimum of 6mm of clearance between the tire and frame. If there is sufficient clearance, continue with the installation. If you have insufficient clearance, we recommend installing a different rear tire.
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.
The Ripmo AF fits a 22 oz Purist bottles on size small, and a 26oz on all other 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.
