Can I combine a Nimbus Aluminium Seatpost (25.4) with the Kris Holm Freeride saddle? Do the parts fit together?
If you mean this one, then yes - the 4 bolt mounting pattern is the same standard as on the Nimbus aluminium seatposts.
Where people tend to get caught out is with the Fusion Zero/Fusion One saddles that use a Pivotal post mount, similarly to the Nimbus Shadow Handle.
Yes. That one. Then I will get it.
I did notice the Pivotal thing.
