  • 'The demise of British component manufacturers'?
    hubs with the angled flanges in 1948 9 below THE BRITISH RESPONSE PRODUCTS During the late 1940 s most component companies were required to concentrate on exports which starved the home market Supply only really caught up with demand in 1950 Many adverts of the period stress that export has priority and goods may not be in stock Sturmey Archer ran an advert until 1949 which consisted of a dialogue between a cyclist and a stocks are difficult to obtain at the moment but I ll put your name on a waiting list Lucas ran an advert featuring a picture of some beef steaks explaining that the priority being given to export was enabling the British population to put meat on the table With the increasing economic prosperity import restrictions were eased with the result that for the first time continental products became widely available Gnutti hubs and chainsets were amongst the first products to be both available and affordable It was not until a couple of years later that British companies began to offer continental styled products The remainder of this article discusses some examples Bottom Brackets Bayliss Wiley BW Featherweight bottom bracket set Described as new in 1953 A weight saving of 50g mainly achieved by hollowing out the axle This was a copy of Stronglight with the fixed cup being octagonal and the adjusting cup hexagonal Brampton produced a similar item a year later Both were very high quality items comparable to anything else on the market BW no s 14 and 23 cottered bottom bracket axles With the increasing popularity of derailleur there was a demand for longer bottom bracket axles The no 23 were for a 5 speed and the no 14 for a double chainwheel Until 1953 they had only offered for lightweights the no 15 with ngcc none gear case clearance BW also produced a cottered axle no 8 for the slightly wider Continental bottom brackets shells 70mm as opposed to 68mm and wider on the gear side This was for the 5 pins Stronglight design used by Gnutti Duprat and Durax etc and later by Milremo and TA Large Flange Hubs since the 1930 s large flange hub were known in Britain as the continental It is not entirely clear which continental hub this was derived from It may have been Prior French who in the 30 s marketed very large riveted flanged hubs To meet the demands of fashion in the late 30 s the British Hub Company BHC riveted flanges to the Airlite to create the first version of the Airlite Continental image left These are now very sought after by collectors but have a major flaw in that after prolonged use the rivets work loose Post war the Airlite Continental was a three piece steel barrel on alloy flanges In the mid 50 s BHC introduced the Racelite a copy of large flange Normandy and other similar French hubs BHC marketed the Racelite as the first single piece British

  • Weinmann components
    Cantilever brakes Two versions both made in the mid 80 s A Mafac copy produced after Mafac went out of business around 1984 apparently they bought the Mafac tooling a model aimed specifically at ATB usage Superior quality side pull brakes 605 with quick release on the stirrup Carrera a high priced Campagnolo copy in the mid 70 s The top model 400 black anodised close clearance Carrera 400 stirrups black anodised Polished alloy mudguards stays fitted in French style Also short racer mudguards which were popular in the 70 s and fitted to many sports racing bikes and needless to say offered no protection against the elements Brake tools allen keys brake clamp bolt spanner inverse allen key third hand brake tool Late 70 s concave rims These were extremely strong but could lead to corrosion of the spoke nipples due to the shape of the rim retaining road salt Valve inserts model Alligaro 1950 s According to Weinmann makes pumping almost a pleasure The 730 and 500 in gold red and blue anodised These were stamped De Luxe Lever sleeves white plastic which covered s of the lever blade Hooked to improve finger grip The numeric model numbers refer to the reach in mm with another zero added usually the mid point Thus 500 was between 42mm and 56mm MODEL CHANGES Early versions of the centre pulls have arms with a difference curve Last version of these brakes have the name and model on a black background as opposed to the earlier red There is a version of this brake with solid flat metal instead of a straddle cable model 737 produced in the early 80 s Original versions of the side pulls have the name stamped in large letters on the brake arm without any border until late 60 s The larger the lettering the earlier the brake Final versions of the side pulls have the forward centre bolt replaced with a black plastic reverse Allen key fitting see picture of the Carrera I think this was designed to make centring easier although to me it looks very cheap Earlier rims had a smooth surface later ones have a recessed channel running near the edge on either side Later rims are marked Made in Belgium at some point production must have moved there Indeed rims are still made to this day under the Alesa trademark and very good touring rims they are too DATING Some brakes have the month and year of manufacture on the rear of the arms eg 0576 May 1976 Levers up to about 1964 have Made in Switzerland stamped on one side of the upper lever blade visible when lever is open Progressively the writing on the brake arms become smaller and finally is enclosed in a rectangle Later products are stamped Made in Belgium PERCEPTIONS AND PERFORMANCE Weinmann brakes and rims are not highly regarded by club cyclists or by VCC members They rarely sell at cycle jumbles lacking the period appeal

  • GB Brakes
    known as GB s racing brake Note early 1952 type hooded lever now with built in adjuster The caliper has a Q R lever The main change was for 1955 with a nylon bearing bush and a different type spring GB Sports appeared in about 1953 and appeared as two versions The Sport MK2 had the same changes as the Coureur in 1955 The MK3 1958 is shown with the Arret lever with blue logo The second version was not for retail and was different in that the inner cable had nipples at both ends and no pinch bolt on ther stirrup When GB introduced the Sport they also introduced a model listed in the trade catalogue as for trade i e cycle manufacturers only Here is an example of the Sport trade The differences to note are The inner cable has nipples both ends and the cable set includes the adjustor which drops in the top of the hood The stirrup arm does not have a cable retaining bolt the nipple locates in a slot on the arm My guess is that this would speed up mass production assembly as anyone who has set up brakes with a cable
