We are now shipping our Press Fit 30 to Shimano Hollowtech II bottom bracket cups. These cups allow Shimano cranks to be run in any Press Fit 30 (46mm x 68mm) standard bicycle frame. Similar to the BB30 (42mm x68mm) adapters we released last year, these match the Shimano factory specification for bearing location, so they are very rigid and durable. Bearings and seals are by Enduro. These are available via our online store: http://www.parleecycles.com/store/ or through any of our dealers.
