Overview
The Syndyt 185 Junior is a frame-only BMX racing platform with an 18.5 inch top tube, sized for younger racers moving up from smaller bikes.
Built from the same triple-butted 6061-T6 aluminum as Syndyt's other race frames, it comes in lighter at 2.81 lbs given its smaller size. It uses a Standard Euro bottom bracket rather than the oversized B52 unit on Syndyt's Pro-size frames, and supports 10 or 15mm rear hubs with built-in chain tensioners. No seller description or customer reviews are included.

- Tapered 38/42 head tube

Who it's for
Parents or racers building a Junior-class BMX bike for a smaller rider. Not suited to anyone needing a complete, ready-to-ride bicycle, since this is frame only.
Strengths and trade-offs
Drawn from this product's published specifications.
- Light frame-only weight of 2.81 lbs
- Standard Euro bottom bracket for common crank compatibility
- Supports 10 and 15mm rear hubs
- Built-in chain tensioners
- Frame only, no fork or components included
- Smaller top tube not suited to taller riders
- No customer reviews yet on this listing
Performance notes
The tapered 38/42 head tube is sized smaller than Syndyt's Pro frames to match the shorter top tube, while still accepting a standard tapered fork for precise steering. The Standard Euro bottom bracket keeps parts compatibility straightforward for builders already stocking common BMX cranksets.
