Bottom bracket for Shimano Hollowtech II
Now we produce bottom bracket for both 30 mm axle and 24 mm. The construction of both is identical, more on that below. For the standard key Shimano Hollowtech II. Compatible with Shimano central seal.
Stainless steel bearings
We try to increase the reliability of our products. One of the steps is now to install stainless bearings in all our bottom bracket.
Added 2 sealing rings on the shaft side. The outer ring made a little denser. Because of the tight gland, the bottom bracket rotates tightly, but we measured the loss of friction power. It makes no more than 1 W at 60 rpm, it is not noticeable for legs. Those who wish easy rotation can remove the seals. It will turn out to be a dirt barrier like most of the bottom bracket on the market - a plate above the bearing and a bearing seal.
