Overview
Is the Kalloy Uno 602 the Right Seatpost for Your Bike?
The Kalloy Uno 602 Seatpost earns its place on builds across the price spectrum by delivering exactly what a seatpost should: solid saddle support, reliable clamping, and a fit range that covers most frames. Constructed from aluminum alloy with a dual-bolt clamp head, the Uno 602 keeps your saddle locked in position through varied terrain and riding conditions. Five diameter options from 25.4mm to 30.9mm mean this post drops into a wide variety of seat tubes without adapter headaches or sizing compromises.
The 350mm shaft gives taller riders and those who run a generous saddle height plenty of post to work with, while the straight design keeps installation clean and simple. The dual-bolt clamp allows precise saddle tilt adjustment and holds it firmly once set, which matters more than most riders realize until they have dealt with a slipping saddle mid-ride. Available in black and silver finishes, the Uno 602 suits everything from a reliable commuter to a spare training build. If you need a dependable, no-nonsense seatpost at an honest price, this is it.

FAQ
Good questions
Get to know Kalloy

There's more to Kalloy than this one product. Our Kalloy page has the full Kalloy lineup we carry and more about the brand.
Visit the Kalloy page →What diameter Kalloy Uno 602 do I need for my frame?
Match the seatpost diameter to your frame seat tube inner diameter. Common sizes include 27.2mm for most road frames, 30.9mm for many mountain and gravel frames, and 25.4mm or 26.8mm for older or specific hybrid frames. When in doubt, measure your existing post or check your frame spec sheet.
Is the dual-bolt clamp compatible with all saddle rail types?
The dual-bolt clamp works with standard round-rail saddles. If you are using a saddle with carbon rails, check your saddle manufacturer guidelines, as carbon rails often require a clamp specifically designed for them to avoid damage.
Can I cut the Kalloy Uno 602 to a shorter length?
Yes, the aluminum shaft can be trimmed using a pipe cutter or hacksaw. Mark your minimum insertion depth before cutting, and deburr the cut end to ensure a clean fit in your seat tube.
