The BS25 group bulkhead steerer

The Jefa BS25 type bulkhead steerer incorporates twin high efficiency 25 mm ball bearings, which are double sealed and pre-lubricated for a long and maintenance free life. The lip seal at the front is the especially developed Jefa PUR seal, which contains no metal parts for a life long problem free usage. The stainless steel steering shaft has a diameter of 25 mm to guarantee a stiff and strong steering arrangement for wheels up until 1300 mm diameter. Above 1300 mm wheel size one should add a support bearing at the aft side of the steering shaft (like the BS30 unit). The maximum wheel size accepted is 1500 mm. The large internal brake dish provides an efficient and strong braking arrangement. The number of turns achieved with the various sprockets can be found in our sprocket table.
