Our bikes come with size specific seat post lengths that allow for different rider heights. The amount of drop is noted in our spec sheets under each model. We choose seat post lengths based on the seat posts ability to be inserted all the way to the collar. This mitigates any potential frame damage or kinks to internal cables that may result in suboptimal performance.

Dreadnought E uses SHIS spec ZS44/28.6 upper and ZS56/40 lower cups. All frame fit specifications can be found here 

We offer a lifetime warranty for Dreadnought E to original owners for manufacturing defects. Please consult our warranty page for further details

Both Druid E (2025 or 2026) and Dreadnought E can run a double crown fork as long as it is within the maximum permissible axle to crown measurement:

Druid E: 586mm

Dreadnought E: 605mm

Additionally, the length of the headtube determines whether the upper and lower crowns will fit correctly. Please check with the fork manufacturer’s requirements and cross-reference them with our headtube lengths.

The M1, M2S and M2 motors all have the same mounting standards. Therefore, an M2S or M2 will fit in the frame. Changes to the wiring harness will also be required. Please contact Avinox for further details.

Your bike was built to be compatible with most shocks on the market, both coil and air spring. We haven’t tried every shock on the market, but we do know that it fits anything from FOX, RockShox and Ohlins.
