Plastic, plastic, plastic. KHE just sent out an email to introduce the newest BB they are working on… you may have seen the other BB out there by Eastern this one is a bit different. I’ll let Thomas explain since I am no engineer…. –iTod
These bush bearings, named iglidur® are principally used in other industries, primarily on permanently running applications at high temperatures. Each of them sustain more than 3 tons.
Their advantages are obvious:- They are unbelievably compact and weigh next to nothing- Highest wear resistance- lowest friction- Excellent resistance against extreme conditions like high temperature, humidity, chemicals- Maintenance-free – Lubricant-free – Corrosion resistance – Extremely insensitive to dirt – High accuracy grade
The AFFIX® bush system features strong alloy cups to get the most resistant end-product.
One alloy cup including the iglidur® bush bearing weighs only 36g/ 0.079lbs.
For example: Compared to a regular MidBB (including spacers), the AFFIX bush system saves 120g/ 0.265lbs, while it´s more durable and maintenance-effortless.
We plan to offer the AFFIX® bush system for Mid BB, Spanish BB & Euro BB.
Here you can see pics of the new system assembled on a bike.
