Buying Guide
What frame material should I choose?
Chromoly steel frames (CR-MO) offer durability and a compliant ride quality ideal for rough urban roads and long-term resilience. Aluminum frames are lighter and efficient for fast acceleration and performance riding, but may feel stiffer. Choose steel for comfort and durability, or aluminum for weight savings and responsiveness.
How do I pick the right frame size?
Fixed-gear frame sizes are typically listed in centimeters (cm). For street riding, 52–55 cm suits riders around 5’6″ to 5’10”, while 58 cm fits taller riders. Always reference stand-over height and reach, and consider your inseam and torso length for proper handlebar and saddle positioning.
What about braking and compatibility?
Most frames shown are designed for single-speed or fixed-gear setups with a rear brake hanger or integrated braking options. Verify brake compatibility, axle standards (QR or solid thru-axle), and whether your wheelset supports the chosen braking style. Quick-release (QR) frames simplify mounting and adjustments.
Wheels and tires compatibility
700C wheels with 25C tires are common for track-inspired builds. Ensure the chosen frame can accommodate your wheel width and tire clearance, including any frame clearance for wider tires if desired.
What are practical trade-offs?
Steel frames provide durability and ride comfort but add weight. Aluminum frames save weight and enable quicker acceleration but can be stiffer. Fork choice (carbon vs metal) also influences ride feel and steering response. Balance your priorities: comfort and durability vs. weight and performance.
How to assemble a fixed-gear build
Ensure compatibility of bottom bracket, headset, and brake mounting with your chosen components. Confirm spoke count, chain length, and cog size requirements for a fixed-gear configuration. If you lack experience, seek guidance from a bike shop or a trusted builder to avoid misalignment or braking issues.
