What our customers are saying about Rotor Press Fit 4130 Steel bottom bracket cups

These high-quality replacement bearings offer excellent value, praised for their smooth, precise, and low-resistance performance. They are a perfect solution for adapting a 30mm axle crankset to a press fit bottom bracket frame, fitting Rotor cranks perfectly. The material is durable and resistant, and installation is easy. For optimal performance and water resistance, some users recommend replacing the stock grease before mounting

Very well advised

alejandro

Very good. It's my first time using these bearings. I've been using them for several months now, and they've held up very well in rain and mud. Assembly was easy with the tools, of course. They are BB30.

The only possibility to use 30mm in presfit

2024/02/18

Andrej

The quality is fine. I am concerned about the product's lifespan. The bearing balls are small. Anyway, there is no other option to use a 30mm axle in a press fit frame.

The grease must be changed immediately, even before they are assembled. The original one is no good, it has no water resistance. As for the material itself, it's very good, very resistant and doesn't get slack, no matter how much you use it.

Compatible con Shimano xt

2025/02/21

alejandro

Compatible with XT cranks Press fit BB92 bottom bracket axle 24? A concise answer is appreciated. I´m fed up with Shimano cranks that don´t last long.

Answer of Alberto

No, this bottom bracket is for 30mm axle

Answer of Aitor

They are not cranks for 30mm

Answer of Aquilino

Hi friend, I think these are not suitable for you, since they are 24mm in diameter and these are 30mm. These types are usually for Rotor, Raceface or Ethertin cranks. On the page you will surely find what you are looking for, but first measure the diameter of the bottom bracket axle. https://www.tradeinn.com/bikeinn/es/shimano-cazoletas-del-pedalier-xt-slx-mt800-press-fit/135996932/p

Answer of Alejandro

Hello! They are specific for 30mm axle

Answer of andrej

One order is enough. Item consists of two bearings - all what you need.

Answer of Bedics

There are two bearings (one set) in the package. They have to be replaced in pairs, that´s why there are two in the set.
