Quello che cercavo

Arrived 3 weeks early.

I saw a tutorial video of a guy using this bottom bracket adaptor in a vintage Schwinn road bike. He removed the one piece crankset and original bearing cups, slid this adaptor in the bottom bracket shell and tightened the bolts. Worked perfect. So I purchased one to use on an old Sears Free Spirit I am restoring. Out of the box it looked to be a nicely built product. When I removed the bearing cups from the frame I was restoring, I noticed the bottom bracket shell was not a piece of tubing, but a piece of flat steel rolled into a circle. Well, sort of a circle. I'm sure when the bike was built in 1973 it was a lower quality frame. So the bottom bracket shell was not cut from a piece of tubing like most bikes. They had rolled flat stock into a circle, then added another thicker piece of flat stock to the inner diameter to add strength. It wasn't perfectly round, and the additional piece inside was thick and not very round at all. When I tried to test fit the BB adaptor, it did not fit at all. Long story short, it took days of grinding, turning parts in a lathe, grinding more, cutting and generally trying everything possible to get the adaptor to fit the frame. Finally got it but it was not at all easy or pretty. None of this was the fault of the adaptor! The adaptor is nice and very well designed. All the installation issues were because of the method used when the frame was built. The reason I'm even writing this review is to give another person hoping to just slide it in the BB shell and tighten the bolts a heads up. The online videos are great, but depending on the frame you might be in for a serious challenge.

Muy buen producto, fácil de instalar, buena calidad y ensamble perfecto. Muy recomendable.

Lightweight, exact dimensions, easy to install.

Habe einen coolen Rahmen bekommen der allerdings mit angeblich "Euro BB" ausgestattet war. Musste lange recherchieren und war mir bei der Bestellung am Ende noch immer unsicher ob dieser der richtige ist. Hat jedoch bestens gepasst. Der Adapter muss wirklich mit viel Kraft eingefügt werden. Ich empfehle Schraubzwingen zu verwenden. Am Ende werden beide Seiten gegeneinander verschraubt um sicheren Halt zu gewährleisten. Ich habe trotzdem Buchsenkleber verwendet, um wirklich keine Gefahr einzugehen!

Fa quello che deve,tutto in alluminio anodizzato nero,oggetto robusto ..ci ha messo qualche giorno piu del solito ad arrivare ma alla fine sono soddisfatto
