3T Carbon Round Seatpost 27.2mm 400mm Zero Offset Matte Black Road

This 3T Round Carbon Seatpost (MPN 30514) is a premium carbon seatpost designed for modern road and gravel bicycles that use a standard 27.2 mm round seatpost. Its classic round profile prioritizes ride comfort and compatibility, making it a versatile choice for performance-focused builds across a wide range of frames.

Constructed from high-quality carbon fiber and finished in matte black, this seatpost delivers an excellent balance of low weight (264g), stiffness, and vibration damping. The round 27.2 mm design is favored for its natural compliance, helping reduce road and trail chatter on longer rides while maintaining precise saddle positioning.

Originally specified on 3T Ultra and Extrema frames, this seatpost is not limited to those models and is compatible with any bike frame designed for a 27.2 mm round seatpost. It includes an integrated two-bolt saddle rail clamp for secure, micro-adjustable saddle setup. Designed in Italy and manufactured to 3T’s exacting standards, this seatpost reflects 3T’s long-standing focus on performance, fit, and durability.

While working on bicycles is not difficult, an improperly assembled / tuned bicycle can lead to damage to the bicycle or injury to you. We recommend that you have a qualified mechanic install components and service your bicycle.

Brakes - It is not uncommon that new hydraulic brakes would required bleeding. While not difficult for a qualified mechanic it is very easy to introduce air into the lines. We strongly recommend you have a qualified mechanic bleed your brakes if necessary.

Wheels - It is not uncommon that a new wheel may require some minor truing and if equipped bearing cone adjustment.

Suspension - Shocks are not easily serviced outside a shop setting. Any adjustment beyond rebound and sag should be done by a shop. Quick note on lockout function, it will not become rigid, it will however be very stiff.

NOTE: STRIPPED THREADS IN CRANKS AND PEDALS ARE DUE TO THOSE COMPONENTS NOT BEING PROPERLY TIGHTENED.  STRIPPED THREADS DUE TO IMPROPER ASSEMBLY / MAINTENANCE ARE NOT COVERED BY WARRANTY.

• Some items we sell qualify for the Manufacture warranty, most do not. Generally items in retail packaging can qualify, OE items do not.   While we do not extend any warranty we will offer a refund on items that fail in the first 30 days.

• Where do you get your stuff? - Trade secret.
• Why do you use your own UPC and not the MFG's UPC? - Using our own UPC's gives us greater influence on the description. Because many of our parts are OE they either do not have a MFG UPC or may differ slightly on what is included. Using a MFG UPC can cause our description to be overridden by a catalog description that may not match what we are selling. Additionally many manufactures use UPC's that start with a 4. Those are not necessarily unique numbers and are not always valid as unique product identifiers outside a store setting.
• You say over and over to have a qualified mechanic work on my bike. What if I want to do my own work? - Not a problem, most repairs are easy and do not require special tools. There are several great instructional resources out there. Just be aware as a novice it will take you longer and components damaged due to improper installation are not covered by warranty.
• Can I pick up my item to save shipping? - Yes, but we are in the sticks. Our closest Starbucks is 30 minutes away. We do ask that you contact us first so we can pull your order. With drive time and gas not many people realize a savings.

Our History

Before disc brakes, before V-brakes, before suspension forks, around the time the first index shifters that actually worked and the first production mountain bikes hit your LBS, Ben Gibbs started Bennett’s Cycle in St. Louis Park, MN. In the late ‘90’s he sold that shop and started experimenting with online sales. Ben started selling on eBay in ’99, back in the day when your default user ID was your email address. If you wanted to get fancy you could change that to your website URL. That ID (can’t put the name here because it included a URL) was one of the first to exceed 100,000 positive feedbacks. 

Our Business Philosophy

Move as many parts as possible without it being a pain. Just keeping it real. Pulling that off is a bit easier said than done. In order to do that we strive to deliver value to our customers by sourcing quality products at prices that make you ask is that for real? We commit to being honest and fair in our transactions with customers and suppliers. If a dispute arises, if we are at fault, admit it early. We are committed to providing a work environment that recognizes the unique value of each of our employees. And recognize that work, while it consumes much or our time, is only a part of who we are and by being welcoming and accommodating when life spills in. The only slightly unreasonable thing we ask of them is to stay out of our parking spots.
