DINKY Bottom Bracket

DINKY Bottom Bracket

The DINKY bottom bracket fits children's bikes that need reliable, low-maintenance performance. It offers durability, consistent pedaling, and low weight for everyday riding. With a cold-forged, phosphated steel spindle, DINKY handles the stop-start demands of children's cycling. 

ZZ ball bearings keep friction low and pedaling for young riders smooth. Composite cups reduce weight and resist corrosion, helping bike brands build light, practical, long-lasting children's bikes.
