    The old girl is still trucking along nicely with the SickBikeParts prototype double row freewheel bearing system; doing it's bit to cope with the strain of hauling load after load after load of firewood.

    I hope that the ultra heavy duty bearing system is now in volume production, because it's exactly what the shift kit needs for bullet proof reliability.

    Wow! That must be a handful. - Really neat picture.

    It handles surprisingly well. Obviously you need to be sensible with cornering speed, but the trailers tow quite nicely.
    The braking side of things is taken care of by a 9" front disk rotor, which provides adequate stopping power, at speeds appropriate for such a load.

    It's a damn lot of fun hauling a good 400 lbs (combined trailer weight and cargo weight) with the engine and SBP shift kit (and optional chain tensioners) working to the limit of mechanical integrity, yet doing it with repeatable reliability, mile after mile after mile.

    That's just nuts Fabian! Is the lead bike a "tractor"?
