LiBCo. wide shell Spanish BB

We are now offering bottom brackets that fit the new Tanatos frame. The frame employed a special variation of Spanish bottom bracket with wider spacing in order for the pursuit of ideal geometry, strength, lightweight, and reliability. The bearings are identical to Spanish ones used for some of the BMX bikes, but the intermediate spacer measures different at 71mm in length (which actually is identical to the spacer used for outboard Euro bottom brackets from some other parts makers). You don’t normally need this kit because the Tanatos frame set always comes with this, but you can make use of it if the original BB kit becomes defunct, you need just bearings for another frame, etc. This kit comes with a 71mm sleeve as well as spacers 3mm and 1.5mm in thickness, 4 pieces each.
