Minimum post exposed refers to the total amount of post that must extend beyond the seat collar on the bike frame.
Maximum post exposed refers to the greatest length the post can extend out of the seat tube on the bike frame.

All posts ship with 41" of actuation cable. This will fit most frames. If your frame will require more cable, please send us an E-mail indicating what length you will need.

All posts are 27.2. If you need a shim to fit another size, we stock 30.9 and 31.6. Please specify at check-out if you need a shim and the size. At this time, we are not taking orders for custom configurations. Custom posts will require additional time for production. We will let you know the time frame for production and delivery when we begin shipping custom drops. Shipping and Handling $6 for all orders shipped within the US. Sorry, No International orders, except Canada.
