Dynaplug

Dynaplug makes one category of product — tubeless tire repair tools — and has been refining that focus since 1991. The system works on a straightforward principle: a proprietary plug tip inserts directly into the puncture and fuses permanently to the tire casing, without reaming the hole, applying chemicals, or waiting for anything to cure. Dynaplug states the approach handles 98% of all tubeless punctures, and every tool and plug is designed and manufactured in Chico, California.

At RA Cycles, the Dynaplug collection covers the full range: the Megapill for maximum plug capacity; the Air Kit in road and MTB versions, which inflate and plug in a single step; the Micro Pro for compact carry; the Racer Pro for a clean, fast kit; and the Carbon Ultralite Racer for weight-sensitive builds. Bullet-tip and pointed-tip plug refill sets are also in stock.

About Dynaplug

Dynaplug was founded in 1991 — well before tubeless became standard on road bikes — with a single focus: a fast, permanent tubeless tire repair that doesn't require reaming the puncture, applying chemicals, or waiting for anything to set. The system relies on a proprietary plug tip that fuses to the tire casing on insertion, sealing the hole from the inside. According to Dynaplug, that approach handles 98% of all tubeless punctures. Every Dynaplug tool and plug is designed and manufactured in Chico, California, and the product range is built around that same principle at different form factors — from bar-end-integrated tools to kits with integrated CO2 inflation. Learn more at dynaplug.com.

RA Cycles stocks the full Dynaplug lineup: the Megapill for maximum plug capacity; the Air Kit in road and MTB configurations, which inflate the tire while seating the plug in a single step; the Micro Pro for compact everyday carry; the Racer Pro for a balance of speed and simplicity; and the Carbon Ultralite Racer for weight-sensitive builds. Bullet-tip and pointed-tip plug refill sets are stocked separately.

50 YEARS AND COUNTING

From a Brooklyn storefront to flagships in Walnut Creek and Miami, from handwritten mail orders to a fully digital custom bike builder — RA Cycles has spent half a century doing one thing: serving riders who demand the best. That half-century belongs as much to you as it does to us. The riders who kept coming back, who sent their friends, who trusted us with bikes that matter — you're the reason we're still here. Here's to the next fifty.
