AM120

A replacement seatpost listed by Himiway model, because diameter and length both vary across the range: from a 27.2mm post on the A3 and B3 up to a 34mm post on the Big Dog, in lengths from 180mm through to 360mm. The post has to match the frame's seat tube exactly, so this is one part where estimating the size is not an option.

Posts of the same diameter can be swapped between models, which gives some flexibility if you want more or less length than the original, so measure what is currently in the frame before ordering. Two details are worth checking: the A7 is listed in a Large version with a 180mm post and a Regular version with a 350mm post, and the D5 2.0 family is offered in both 270mm and 350mm lengths at 33.9mm diameter.

This part is covered against defects in materials and workmanship on arrival. Himiway does not publish a separate warranty term for replacement parts bought on their own, so contact Adventure Motion support with your order number and photos if something arrives faulty or fails early, and we will confirm coverage and handle the claim.

Wear items such as tires, inner tubes, brake pads and brake rotors are consumables and are not covered beyond transit damage. Damage from crashes, incorrect fitting, modification or use outside the part's rated limits is also excluded.

How do i find the right size?
Measure the diameter of the post currently in your frame, or read the size printed on it, then match that to the option listed for your model.
Can i use a post listed for another himiway model?
Yes, as long as the diameter is identical. himiway states that posts of the same diameter can be interchanged between models.
Which a7 option do i need?
The a7 large takes a 31.6 x 180mm post and the a7 regular takes a 31.6 x 350mm post. the product images show how to tell the two frames apart.
Is a saddle or seat clamp included?
This listing covers the seatpost. your existing saddle transfers across to the new post.
What should i watch for when fitting?
Use the correct clamp torque rather than overtightening, and make sure the post is inserted past its minimum insertion mark if one is shown.
