Eje crankstel BSA 122,5/68 mm -BB-UN300 Cuadradillo (LL123)

Todo bien, pero a la segunda.El primero que pedí a devolución, por no ser el descrito, no se sabe si por culpa de Shimano que se equivoco de caja en el empaquetarlo, cosa rara.O porque en Amazon les dio por mandarme un producto de devolución.Y ya sabemos que en las devoluciones el encargado de turno no mira gran cosa.

The cartridge arrived within a week with free shipping which I was impressed with, but the crank arm bolts were not provided with the BB cartridge.

This bottom bracket is for my e bike which I use pedal assist on extensively. As it's a legal 250W motor I have to put in a bit of personal oomph, especially on hills so the mechanics of the bike are very important. The bracket on the bike in comparison (Chinese bike) was a loud mess although it's rotation was adequate and would have lasted longer, however eyeing the corrosion evident on it, decided to replace the bracket and I'm so glad I did. The Shimano one is silent and very smooth with excellent build quality. I've been gradually replacing the original parts on the bike with more upmarket replacements as time goes on and it'll last for many years as a result. This bottom bracket is very good value for money and raises the bar quite a bit compared to the lousy original part.It didn't last for many years as hoped, just a little under two years. Bearings corroded on chainring side. Disintegrated with complete collapse on one side. Having said that, I've replaced with this item again. It did run well up until the failure point, it's reasonable price for two years of constant use won't break the bank.

Excellent Shimano quality, exactly as expected really.

Good quality, easy to fit. All nasty noises and movement gone.
