BSD Focus Frame (Forest Green) (21") (Gaspar Guendalin)

BSD Focus Gaspar Guendalin Frame Description:

The BSD Focus Frame is Gaspar Guendulain’s signature model, built with geometry that sets it apart from the current wave of short street frames. With a longer 13.5–14” rear end and a taller 10” standover, the Focus delivers stability and control for powerful riding styles. The 72° forward-angled seat tube makes barspins easier by positioning the seat perfectly for pinching, while toptube options up to 21.5” reflect the exact length Gaspar himself rides. Reinforced with external gussets at the headtube junctions, 7mm thick invest cast dropouts with integrated tensioners, and butted tubing throughout, the Focus frame is dialed for strength, balance, and precision. Built to handle the abuse of modern riding while still offering classic style, this frame is ready for riders who want Gaspar’s proven geometry under their feet.
