There are some cases where spacers are okay to use with a Hollowtech2 crank, like with a road triple set up, and some MTB applications, but in general, Shimano cranks don't need spacers. If you are going to use spacers, watch this video for guidance to ensure you're not putting you crank, and perhaps yourself, in danger.
Press-fit requires precision. If something is not in spec, the system may work, but performance can be poor. The key to succeeding at a pressfit operation is to ensure all the components are the right size before you begin.
At BBInfinite we live to stop bottom bracket creaking. A creaking bottom bracket ruins a perfectly nice ride. It's also embarrassing when you are riding with a group and your expensive carbon bicycle is creaking and squeaking like a secondhand Walmart bike. The worst part is that a creaking bottom bracket is telling you that there is extreme inefficiency plaguing your drive train.
Exorcise the creaks with our one-piece design, hub-style bottom brackets. A unitized design prevents the inevitable creaking of multi-piece units. Furthermore, a one-piece design (OPD) maintains perfect bearing alignment for incredible spin and extreme durability.
Become infinitely faster...and quieter...with BBInfinite.
