Crank Bearing Preload Adjuster for Bb30/Pf30

A cinch to fit, just make sure you fit it the right way round and you shouldn't have any problems. Plenty of tutorials on YouTube etc

Recambio original para mis bielas SRAM. Supongo que sería mejor que estuviera acompañado de unas instrucciones de montaje, aunque no es nada complicado.

Used it to preload the Sram Red BB3 0 crankset, the 10 speed one now using on 11 speed system. It took me awhile to figure out how to use it since there are no instructions and you tube videos are not that great. First I used it with the smooth face of the preloader facing the bottom bracket but as soon as I tighten the crankset the crank would bind and barely move, it turns out that the wings of the preloader were touching the outside of the bottom bracket and not the bearings dust cover. So I turned the preloader around with the preloader smooth face now facing away from the bottom bracket, then I tighten the crankset and again it was binding but this time the preloader wings were not touching the bottom bracket, it made no sense. The trick that solved this issue was, to tighten the crankset a little bit and then turning the crankset a few times and repeat this until fully tighten. Now the crankset turns very freely without any play. The preload adjuster is in the extreme position totally away from the bottom bracket and no crankset play.

Um das geringste Spiel in der Kurbel zu beseitigen ist es perfekt. Manchmal sind Herstellerseitige Produkte einfach besser.
