Pre-Order

With Pre-Order, you can purchase the latest items added to our store in advance of them arriving with us.

Your Pre-Order is prioritised (at no additional charge); meaning that as soon as the product arrives with us, we can wrap it straight back up; ready for collection via Click & Collect or despatch to you — it often never even hits the stock room shelves!

Pre-Launch

With Pre-Launch, the date when we expect to receive the product ourselves is still a little too hazy to be confident in accepting Pre-Orders.

So, instead, you can submit your email address against the item you are interested in and we will email you as soon as stock arrives on the system.

The dates we provide are based on indications given by our suppliers. Whenever we get updated information from our suppliers we will endeavour to update the Estimated Delivery & Collection Dates provided on product pages.

We estimate this will be ready for despatch to you or collection via Click & Collect on Undetermined

Bontrager Line 34.9mm Dropper Post in Black

Season:All Year Round

Brand:Trek

Code:41485BLK

A reliable dropper seat post with a 3-key chassis design that minimises shaft play for a post that provides smooth and consistent travel adjustment. The Bontrager Line dropper seat post offers reliable and infinite adjustability within multiple dropping ranges to suit riders of all types. The air-sprung hydraulic locking cartridge offers infinite adjustability within dropping range, while the 3-key chassis prevents rotation for a stable ride and provides additional lateral rigidity, minimising play. The 2-bolt rocker head with micro adjustment allows for easy saddle tilt adjustment.

This dropper post features a shorter overall length compared to previous versions, allowing more adjustability and frame compatibility. It includes the post, cable, and housing; the lever is sold separately. It is compatible with Universal Lever, Under Bar Lever, and Elite Under Bar Lever.

Internal cable routing keeps the housing tucked away and free from moving wheels. The frame must be compatible with internally routed seat post routing.

Travel Reducers:

Fine tuning your travel is fast and simple. Travel reducers are available in 10 mm and 30 mm sizes and install in minutes. Simply loosen and lift the collar and fitting, align the reducer, reinstall the fitting and tighten the collar back up. Getting the perfect fit is easier than ever.

MaxFlow Technology:

MaxFlow technology moves hydraulic fluids through the system quicker, for a faster return and smoother overall operation.

Ease of Use:

The Line Elite 34.9 requires 20% less saddle force to lower the saddle and comes with one of the easiest installations in the business.

Design:

The post's larger 34.9 mm diameter allows for an increase in structure strength and provides better performance with less stiction, less side-play and better durability.
