The Retrospec Beta Series Fixie is the ideal commuter bike with a hand built steel frame and horizontal dropouts, double wall rims, sealed bottom bracket, and brand name components throughout. Also included is a fixed-gear/single-speed bike that mixes speed and sleekness with performance and durability. Riding fixed or single-speed means low maintenance, simple and efficient design, and allows you to connect to the road in a way that other types of bicycles cannot do. All of our custom fixed gear bikes come with CST High Performance tires that will have you riding fast and smooth, and without having to worry about getting a flat on imperfect pavement!

Our fixies come in a variety of stunning signature color combinations, from the hot pink and electric blue Betty Davis to the black and red El Diablo made popular by celebrity soccer star and international icon David Beckham. No matter what your personality is, one of our Beta Series custom fixed gear bikes is sure to suit your individual style.

Retrospec’s Beta Series bike features silky smooth KT hubs with flip-flop hub on the rear wheel. The hub comes with a fixed-gear cog and a freewheel, so you can ride fixed or coast. Both front and rear wheels come with 32 spokes and are built with lightweight 41 mm Super Deep-V rims.Wheels that are deep enough for optimized performance but never too heavy. Our wheels also come with a resilient nylon rim tape and CST Super-HP tubes and tires (700x23c).

Retrospec is the only bicycle company in the world that can claim bar-spin clearance, no toe-overlap, and flat top tube all in one frame. All Beta Series Retrospec custom fixed gear bikes have bar-spin clearance on all size frames. If you aren't tricking out on your fixie now, you probably will someday soon because the Retrospec Beta Series makes it so easy. Our frames are uniquely designed to avoid any chance of a toe overlap and all our bicycles size 49 cm and larger come with a flat top tube for a traditional track-style frame.

We strongly suggest that you take your bike to a professional bicycle mechanic to be built and/or checked out to ensure that the cog and lockring are tightened, the brakes adjusted, and the wheels trued.
