  • paddle hubs first used ?

    Hi fellow Greeves people, as some may have noticed I have an advert wanting paddle hubs, these are for a 1958 hawkstone sas that at the moment is a pile of bits. A friend asked if indeed it would have had paddle hubs and what year they were introduced and I didn't have an answer.
    I have assumed that all hawkstone models would have had paddle hubs as standard fitment and they would have been an extra on other models, please shed some light on this someone.
    Thanks in advance, Stace.

    1958 I think, initially on works bikes (Stonebridge was using them in June 1958) but Bickers had standard hubs in April 58. (see pages 30-31 in C&W Greeves book)

      The paddle hubs were first used on the 1958 ISDT bikes - the famous "LHK" machines. These prototype paddle hubs had thicker fins than the later production units. The objective was to stiffen the steel brake drum to reduce distortion, and also (in theory) to improve brake cooling.

      250cc Hawkstones had them as standard. On the 197cc scramblers they were an optional extra. They soon became available as an extra on other models of course.

      It's all "the book", folks...

          I believe that they were introduced for production in 1959

            Christmas is on the way and so hopefully the book will be too. It will sure beat socks and a jar of pickled walnuts, the usual fare!

                Hi Stuart,

                Interestingly, the only drawings I have ever seen for the paddle hub shell assemblies give a date of 2/12/58 (see attached.)

                Presumably, these are for the later 'production' units, which would seem to tally with your comment.

                I've also attached a couple of extra pics for those new to Greeves who may not have seen these units before. As mentioned earlier, these were cast 'muffs' which were 'shrunk' onto standard British Hub Company 'tin' (steel) hubs in order to reduce deformation of the hub and aid heat dissipation, albeit at the cost of additional weight.

                Apparently, Brian Stonebridge once said that he prefered the paddle hubs for hot/dry/hard conditions and the standard hubs for cold/wet/soft going.

                A couple of years back, I actually saw some 'replica' alloy muffs that someone had cast, I'm guessing using an original pair as a pattern.....

                Brian.

                  The 1958 sales brochure shows the 20sa,24sa and 25sa with tin hubs.In 1959 they had paddle wheels and the rear chain oiler in the swinging arm as Tims 25sa has

                    Stuart, I was agreeing with you...the date on the drawings for the 'production' alloy muffs given as 2/12/58 seems to be in line with Greeves policy of announcing next years new models towards the end of the previous year, including those fitted with paddle hubs, hence 1959 models.

                    For all I know there may be earlier drawings for these parts....I had these to hand so thought I'd post 'em for additional info.

                    Brian.
