Overview
The Syndyt 215 Pro 2XL is a bare BMX racing frame, not a complete bike, built from triple-butted 6061-T6 aluminum with a 21.5 inch top tube for taller or Pro 2XL class racers.
At 4.1 lbs it keeps weight low while a tapered 42/52 head tube (1 1/8 to 1.5 inch) accepts standard tapered forks. The B52 oversized bottom bracket ships with an adapter so it can take multiple crank standards, and the rear end supports 10, 15 or 20mm hubs with built-in chain tensioners, which matters most for riders swapping wheels between axle sizes. No description copy or customer reviews accompany this listing.

Who it's for

Performance notes
The tapered 42/52 head tube geometry is built for precise steering under race conditions, and the B52 bottom bracket's included adapter lets the frame take different crank standards without needing a separate purchase. Integrated chain tensioners at the dropouts keep chain tension consistent across the 10, 15 and 20mm hub options it supports.
