Neco B920AL Catridge Bottom Bracket Square Taper JIS with French thread (right-hand thread on both sides) - M 35x1 (1.378" x 25.4 tpi), shell width 68mm. With aluminium cups, sealed industrial bearings and a full axle made of CrMo steel, available in lengths: 103mm to 131mm, weight: 249g (103mm axle).
Please note: we replace the cups of the bottom brackets, i.e. the BB itself is labeled with BSA dimensions (see pictures) as it comes from the supplier with BSA cups - we then replace the cups by French thread bearing cups! The bearing cups also come from Neco, so these are original spare parts.
