Pro LT road bike seatpost, 0mm setback, black aluminium 27.2-30.9-31.6mm

A reliable and versatile aluminium seatpost

The PRO LT seatpost with zero offset is designed for cyclists looking for a robust, simple and affordable solution for fitting or refurbishing their bike. Made from AL-6061 aluminium, it combines stiffness, durability and ease of adjustment. It is available in diameters of 27.2, 30.9 and 31.6 mm, with a length of 400 mm and a setback of 0 mm for the relevant versions.

Its zero setback allows the saddle to be positioned more directly above the seatpost’s centreline. This is a useful feature for cyclists wishing to move their riding position forward or return to a configuration close to their bike’s original set-up.

Part numbers by diameter

These part numbers are listed by PRO/PRO Bikegear distributors for the various versions of the LT without recoil.

AL-6061 aluminium: strength and durability

The PRO LT is made from AL-6061 aluminium, an alloy commonly used for bike components requiring a good balance between mechanical strength, stiffness and weight.

This construction makes it a seatpost suitable for regular use, particularly where reliability is prioritised over minimising weight. The 27.2 mm version is advertised at approximately 265 g for 400 mm, according to manufacturer’s data cited by several distributors.

0 mm setback: to optimise saddle position

The 0 mm setback is one of the key features of this seatpost.

Unlike a seatpost with 20 mm of setback, the seat clamp is positioned without any rearward offset. This allows the rider to adjust their position on the bike without changing the saddle.

A seatpost with no setback may be particularly useful for:

• cyclists wishing to move their saddle forwards;
• adapting the position to a particularly long frame;
• achieving a more centred position;
• making an adjustment following a postural assessment;
• replacing an original seatpost with zero setback.

Tip: the setback should not be chosen simply to gain a few centimetres. It directly affects the position of the pelvis and the pedalling action. Any significant adjustment therefore warrants a check of the saddle height and fore-rear position.

Single-screw clamp and standard rails

The PRO LT uses a single-screw mounting system to secure and adjust the saddle. It is compatible with standard 7 x 7 mm round rails.

Before fitting, however, check the cross-section of your saddle’s rails. Some modern saddles use oval or oversized rails, which require a specific rail clamp.

A seatpost suitable for different types of bikes

Although it is particularly well-suited to road bikes, the PRO LT is available in several diameters and can also be used on mountain bike or gravel bike set-ups, provided the seatpost diameter and the manufacturer’s specifications are adhered to.

The three diameters available cover a wide range of standards found on modern frames:

• 27.2 mm: very common on road bikes and some gravel bikes;
• 30.9 mm: common on mountain bikes;
• 31.6 mm: very common on mountain bikes and some road and gravel bikes.

The diameter must correspond exactly to the internal diameter of the frame’s seat tube.

400 mm in length for a wide range of adjustment

With a length of 400 mm, the PRO LT offers plenty of scope for adjusting the saddle height. This is particularly useful on frames with a short or steeply sloping seat tube.

Please note, however: a seatpost should not simply be adjusted to the desired height. You must adhere to the minimum insertion depth specified by the manufacturer and ensure that sufficient length of the seatpost remains inside the frame.
