Question
Thanks for adding this item! Can I have a sleeve that is 5.5 or 6mm recess so that the hydraulic brake hose could pass through the bottom bracket area? CCJ asked on 21 June 2021
Answer
The dimensions are fixed by the standard, the sleeve section is 36mm, the outside of the bottom bracket is 47mm, so that's 5.5mm as a minimum. admin answered on 21 June 2021 store managerstore manager
