Description and materials
- New Monty Kaizen 20” frame, exclusively designed by legendary Spanish brand Monty.
- This is a mid-range frame whose design, versatility and performance make it ideal for building a bike of any range: from beginners to high-performance bikes.
- Developed and tested for months by Monty team riders Ion Areitio and Vasek Kolar, and used to build the new Monty Kaizen 218, 219 and 220 bikes.
- Made from 6061-T6 aluminium, which ensures the perfect balance between great performance, low weight and affordable price.
- 110mm long, 1 1/8” diameter standard head tube, compatible with internal headsets. It has a large front hole that helps remove any excess material as well.
- The main tubes’ shape is inspired by previous Kamel frames, but they’re now optimized to ensure reliability.
- The top tube is gusseted to the head tube to increase front end’s stiffness and strength.
- Standard 68mm bottom bracket tube, designed for threaded bottom brackets with standard 1.37”x24tpi thread.
- Features bashplate mounts for traditional bashplates (with vertical mounts).
- The seat stays are reinforce with a built-in brake booster that increases stiffness considerably.
- Features both 4-bolt and Post Mount 160mm brake mounts.
- Flat, horizontal dropouts, spaced at 116mm and designed for use with snail cams.

The 7 Compatibility Keys
Below you can find the main details you need to consider when installing any components on this frame:

- 1) Headset. This frame has a standard headtube with 42mm inner diameter, compatible with 1 1/8” internal headsets.

- 2) Bashplate. This frame has bashplate mounts for traditional bashplates (with vertical mounts). This means it’s compatible with Monty’s Eagle Claw bashplate and those with the same dimensions.

- 3) Bottom Bracket. A threaded BB with standard 1.37”x24tpi thread must be used, therefore any traditional or BB30 threaded BBs can be used (Try-All, Hashtagg, Bonz, etc.).

In order to prevent the cranks from rubbing the seat stays, which may happen due to varying crank offsets for each model, it’s recommended to install a 127,5mm or 128mm wide bottom bracket.

- 4) Rear Brake. This frame has both disc and rim brake mounts.

It has Post Mount rear disc brake mounts, so be sure to use a disc brake of that type. Post Mount brake calipers sit onto the brake mounts, instead of sideways (as is the case on IS calipers).

It also has 4-bolt rear rim brake mounts, so be sure to use a rim brake of that type.

- 5) Chain tensioner. This frame is designed for use with snail cams. Since the dropouts are spaced at 116mm, the rear hub width plus the 2 snail cams must add up to 116mm.

- 6) Rear hub. Since this frame is designed for use with snail cams, the rear hub width plus the 2 snail cams must add up to 116mm. Most 20” rear hubs are 110mm wide, therefore you’ll need 2x 3mm-thick snails cams, in this case.

- 7) Fork. The steerer tube on the fork must be long enough to reach the top bolt on the stem’s steerer tube clamp.
To ensure this, you must add the length of the headtube (110mm for this frame), plus the cups bits that sit outside the headtube, plus the headset spacers (if any) and/or dust cover sitting under the stem, plus the length of your stem’s steerer tube clamp. Once you’ve done this, you’ll be ready to know if your fork is long enough so that at least 2mm of it remain above the top bolt of your stem’s steerer tube clamp.
