Bontrager Ajna Comp Women’s Bike Saddle

Season :

Brand : Bontrager

Code : BAC5310

Weight : 0.00KG

The Bontrager Ajna Comp Women’s Bike Saddle is an affordable saddle for road and mountain bike use. The Ajna Comp is built for Bontrager’s Posture 2 position which tends to suit racers and fast, aggressive riders. For road riders this means you’ll be spending a lot of time on the drops. For mountain bikers you’ll likely be riding a fast XC or marathon bike.

The Posture 2 position on the Ajna gives increased stability when sitting on the nose of the saddle and better pressure distribution throughout. The Contour Relief Zone Plus (CRZ+) full saddle cutaway gives better soft tissue protection for extra comfort on longer rides.

To make the Ajna Comp affordable it uses steel rails rather than the titanium and carbon fibre found on the Elite and Pro versions. This does make the ride a little harsher so Bontrager have added extra padding to even the saddle out. Designed for a more aggressive riding position during sustained efforts, the Ajna Comp women's saddle delivers a great fit to preserve comfort and performance.


  • An aggressive Posture 2 saddle that excels both on the road and mountain bike
  • Engineered specifically to provide a better fit and greater comfort for women
  • The Contour Relief Zone Plus (CRZ+) full saddle cutaway enhances soft-tissue protection
  • A wider cut-out and shaped nose provide a stable comfort in an aggressive position

Bontrager Saddles Buyers Guide

Bontrager saddles are not mountain bike or road bike specific. Instead they are based around how you like to sit on the bike. Your posture on the bike determines the position of your pelvis and that in turn determines the shape of saddle you need. Bontrager have 5 posture positions:

  • Posture 5 – Is for leisure riders who want a really upright riding position for casual rides or popping to the shops.
  • Posture 4 – Is for fitness riders and commuters who want a fairly upright riding position but want to be able to go a bit faster.
  • Posture 3 – Is for most road cyclists and mountain bikers who want good balance of performance and comfort. Riders in this position will typically sit with their back in about a 45 degree angle.
  • Posture 2 – Is for racers who like to ride in a really aggressive position. For road cyclists this will mean spending a lot of time on the drops. For mountain bikers it will mean a seat higher than your bars.
  • Posture 1 – Is for triathlon and time trial riders who want to get into a really aero position.

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

You 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 and get it sent out to you - it often never even hits the stock room shelves!


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.

Estimated Delivery Dates
