Sunrace Square Taper 68mm BBS15111

SunRace originated in Taiwan in 1972, initially providing entry-level products particularly to North and South America. The boom in sales of mountain bikes resulted in rapid expansion. Twenty-five years later, it had become clear that further growth would only result from higher level components and so commenced the process of taking the product range up-market.That procedure accelerated after internal hub gear supplier Sturmey-Archer was purchased in 2000. Sturmey-Archer was first established in England in 1902 when they invented the 3-speed internal gear hub.Square taperFor 68mm shellVarious axle lengthsSteel axleSteel cupsSteel sleeveEngineering polymer stopperSealed cartridge bearings338 grams average weight
