Thomson Elite SP-E102-SB Setback Seat Post 27.2mm x 250mm Black MTB Road XC
Has been inspected, Ultrasonic cleaned, and lubed. Ready to be used.
The Thomson Elite SP-E102-SB Setback Seat Post, with the specific dimensions of 27.2mm x 250mm, is compatible with any bicycle frame that has an internal seat tube diameter of exactly 27.2mm.
The 27.2mm diameter is one of the most common and widely used seatpost sizes in the bicycle industry, particularly on:
- Older and Vintage Bikes: Many classic steel-frame road, mountain, and touring bikes were built around the 27.2mm standard.
- High-Quality Steel, Titanium, and Aluminum Frames: For a long time, the 27.2mm size was a de facto standard for high-end frames across various materials because it offered a good balance of strength and weight.
- Modern Road and Gravel Bikes: While some modern bikes use larger diameters for stiffness, 27.2mm remains a very popular size for road, cyclocross, and gravel frames, as the narrower diameter allows for more flex, which can enhance rider comfort by absorbing road vibrations.
Important points to remember for compatibility:
- Exact Match is Crucial: The seatpost diameter must match the internal diameter of the frame’s seat tube exactly. Using a seatpost that is too small will not be secure and can damage the frame, while one that is too large won’t fit.
- Seatpost Shims: If your frame has a larger seatpost diameter (e.g., 30.9mm or 31.6mm), you can use a seatpost shim or reducer to adapt it to a 27.2mm seatpost.
- Setback: The “Setback” in the product name (SP-E102-SB) and the 16mm setback in the specifications indicate that the saddle clamp is positioned slightly behind the center line of the seatpost. This is a fit and comfort consideration, not a frame compatibility issue.

A little about the seller:
I’ve been in the cycling industry for more than 30 years (I know, that makes me old!). I’ve been a professional bicycle mechanic for most of those years, including working locally at Lee’s Cyclery before they became Trek Stores. Now I work from home as a Customer Success Manager for a software team. But I still love fixing up and working on bikes and riding them too!
Purchase from me with peace of mind. Not only can you trust my years of experience, but I will also fit you for the bike and provide any mechanical insight at the time of purchase.
