TWENTY-FIVE YEARS …

YES, FOLKS, 1953 MARKS THE SILVER JUBILEE of the “C.B.” organisation, a proud event for me I can tell you AND for my fellow workmates, many of whom have been with me since the very early days. Always before us has been the ideal of a better bicycle and with all modesty I can honestly say that every cycle and frame we present in the Jubilee catalogue is the best it is possible to produce in each particular class. Furthermore, when you get on your “C.B.” you’ll find it FITS you—you become part of the machine. This is due to design—not accident. We have made a constant study of this subject and give you the benefit of 25 years’ unparalleled experience in the lightweight field. Here at the “C.B.” Works we never stand still, always we are seeking and finding means to give that little extra in design, materials, workmanship, finish and service, and that’s what keeps us “up the front.”

It’s teamwork that does it, right from catalogue to finished product—from the lass who licks the stamps to me “what licks things into shape.” And don’t forget you’re always welcome to spend a couple of hours here at Clapham seeing for yourself what goes on—from drawing board to workshop, on through shotblasting, filing, inspection and so on right through to final assembly—the “whole works.” Drop me a line or give me a ring. I’ll even put on my jacket specially for your visit !

Remember, your “C.B.” dealer is part of the team too ! Just as you place your confidence in Claud Butler, so you can trust him—he speaks the same language as you and me—and is ready, capable and EAGER to give you that service which has built the “C.B.” name.

Proof in performance is our humble boast. “C.B.” doesn’t pick the winners, it’s the winners who pick “C.B.”

Here’s to you and here’s to us and here’s to the NEXT 25 years … your “C.B.” will still be “going strong.”

. so long,

Claud Butler [facsimile signature]

Dear Sir,
I enclose receipt for Avant Coureur frame which I received to-day, for which I thank you.
It came up to all my expectations and was worthy of the name it bears. I hope to be successful on it in the coming season.
G.M. (Scarborough).

Dear Sir,
As this is my final letter to you I should like you to know that the machine is all that it was expected to be and more; thanking you for a really first class job.
E.A. (Maesteg).

Dear Mr. Butler,
I am just writing to tell you what a lovely bicycle you have supplied me with and I would like to thank you very much for letting me have it so quickly.
It is a smasher and the envy of all the boys at school. Again thanking you,
P.B. (Herne Hill, S.E.24).

Dear Claud,
Please find enclosed delivery note for L.B. Tandem duly signed by me. I must say how delighted I am with the machine. It is everything I expected of it. All praise is due to your staff for the fine workmanship of same and rest assured I shall recommend your name at every opportunity.
Thanking you once again for such a fine job and proving to me that C.B. is the goods.
H.G. (Plymouth).

Dear Sir,
Many thanks for prompt delivery. When I reached home there was quite a crowd of fellow cyclists who had heard of the delivery and were all waiting to witness the unwrapping. When the wrappings had been completely removed there was a long critical silence which was broken by the words, “what a beauty”; a remark which I heartily endorse.
I have vainly searched my vocabulary for suitable superlatives but words fail to express my feelings for your achievement. Because that is what the “Avant Coureur” really is, it is a credit to you and your organisation. Thanking you once again for a really beautiful job, I am eagerly awaiting news of wheel delivery for my cup of happiness to be full.
S.P. (Walsall).

Dear Sir,
I thought I would take this opportunity to let you know that I received the bicycle safely.
Since the machine arrived I have had opportunity to ride several hundred miles with it and give it a thorough examination. The workmanship is the finest I have seen on any bicycle and the road handling is very lively and completely suitable to my needs. You were certainly correct in stating that the complications which arose over currency were very minor in comparison to the satisfaction that I anticipate in owning such a fine machine.
J.E.M. (Philadelphia, U.S.A.).

CLAUD BUTLER IS FAMOUS NOT ONLY IN RACING CIRCLES—he also produces the finest Touring, Club-riding and General-purpose models. These too incorporate those sound designs, special materials, exclusive features and manufacturing techniques which have been developed, tested and proved in the long succession of victories by C.B. riders in both classic and local events all over the world. And these riders continue to demonstrate with each fresh triumph the fundamentally superior technical ability and craftsmanship embodied in all Claud Butler bicycles.

EXCLUSIVE FEATURES of Claud Butler Lightweight Bicycles

Every Claud Butler Lightweight has its numerous special features, some examples of which are given below. It is such imaginative conceptions, scientifically designed, brilliantly produced and proved sound by practical test, which demonstrate the go-ahead policy of this Establishment and provide one of the many reasons why Claud Butler is always in the lead.

(1) (2) (3)

C.B. BI-LAMINATED CONSTRUCTION

The greatest advance in frame building since the evolution of the “safety” bicycle. 25 per cent. stronger than the ordinary brazed joint, as proved by official N.P.L. tensile test. Enables me to build your frame to any desired angles (if practicable) without lug “pulling.” Proved sound by practical demonstration on the roads and tracks of the World. (Including all post-war World’s Championships and Olympic Games series.) THIS IS THE TYPE OF FRAME CONSTRUCTION WHICH I RECOMMEND.

(1) NEW ALLROUNDER BI-LAMINATIONS. The original C.B. design elaborately feature cut, bringing the advantages of this revolutionary bi-laminated technique within the reach of all lightweight enthusiasts.

(2) OLYMPIC SPRINT BI-LAMINATIONS. Judge for yourself the attractive appearance, rugged strength, neat design and light weight of this Super bi-laminated frame jointing technique. Now standard specification on Olympic Sprint models.

(3) AVANT-COUREUR SPECIAL BI-LAMINATIONS. The very latest in bi-laminated construction, exquisite well balanced design, plus the rugged strength that goes with bi-laminated frame jointing technique.

(4) C.B. WRAPOVER SEAT STAY TOPS. Originally introduced on C.B. Path models, this feature so effectively stiffens up the rear triangle whilst improving the appearance of the seat cluster that I now include it on the majority of road models as well.

(5) THE C.B. SEAT CLIP. Die cast in phosphor bronze, chromium plated and fitted with an effective 5/16″ dia. bolt and nut, this is by far the most efficient seat clip now in use.

(6) C.B. PATH REAR ENDS. These rugged reinforced ends are but one of the many reasons why C.B. Path models are so widely used. Made of 9 S.W.G. 30 tons per sq. in. steel and reinforced with 14 S.W.G. plates, a full 2″ slot makes provision for a wide range of gear ratios without interfering with total chain length.

(7) C.B. SPECIAL GUIDE TUBE at bracket for exposed gear cable. By far the most effective method used for open gear cables on the market today.

(8) C.B. WORLD’S CHAMPIONSHIP SPRINT LUGS. As illustrated on left. Produced from really high grade steel throughout (including the bracket shell), these lugs, whilst being slightly thicker than the average pressed lug, are effectively and decoratively lightened by the very attractive cutaway feature, so building up a light but immensely strong brazed frame.

(9) C.B. UNIVERSAL CLUB LUGS. As illustrated on right. A set of strong lightweight pressed lugs, quite attractively cut away, retaining strength whilst improving appearance and resulting in a first-class job at reasonable cost.

CRAFTSMANSHIP –

Craftsmanship is exemplified in the versatility of the C.B. organisation. During the war years, for instance, bicycle manufacture was curtailed in favour of Aircraft and Radar Equipment production. Of more general interest are the machines illustrated below. If you want anything ‘tubular’ ask Claud Butler to quote.

UNICYCLES

This is one I made for the famous Moxham Trio. I also make small ones with cranks mounted on the wheel spindle, or larger ones with countershaft drive. The tallest unicycle I have made (so far) was one 12 ft. high!

POLOBIKES

Designed and built to the ideal specification as a result of personal experience on the polo field in actual league competition. Not the cheapest polo machine you can buy (although quite moderately priced) but certainly the best.

PACE-FOLLOWERS

Built to U.C.I. and/or N.C.U. regulation dimensions. As used in successful record attempts and competition at home and abroad. C.B. pace-following machines are preferred by the majority of well-known riders whose names, for reasons you are well aware, cannot be mentioned here.

TRIPLETS AND QUADS!

Multiple seat machines are a speciality of the C.B. establishment. Three-seaters, Four-seaters, yes, and even Five-seaters built by C.B. may be seen on the roads of the world doing yeoman service, from Wyoming to Glasgow and from Bristol to Madras. Claud Butler will gladly quote you on hearing your requirements.

[A page of special machines: a photograph of a man in a cap and knee breeches riding a tall unicycle and pointing toward the text runs the full height of the left edge, beside retouched pictures of a polo bicycle and a three-seat triplet tandem and a three-quarter view of a pace-following track bicycle with wide swept-back handlebars. The polo bicycle, the triplet and the pace-follower each carry a Claud Butler down-tube transfer.]

FRAME DESIGNS

CLAUD BUTLER CAN BUILD TO ANY PRACTICAL DIMENSIONS AND ANGLES, BUT BEFORE DECIDING TO HAVE A MACHINE BUILT TO YOUR OWN IDEAS CONSIDER CAREFULLY THE VAST WEALTH OF EXPERIENCE AND TECHNICAL KNOWLEDGE EMBODIED IN THE DESIGNS SHOWN HERE. IF OWING TO SPECIAL CIRCUMSTANCES YOU STILL FEEL YOU NEED SOMETHING DIFFERENT, SEND A NOTE OF THE FEATURES, ANGLES, MEASUREMENTS, ETC., THAT YOU REQUIRE (IN ORDER OF IMPORTANCE) TO “C.B.” EITHER DIRECT OR THROUGH YOUR AUTHORISED DEALER. CLAUD BUTLER WILL ADVISE YOU WHETHER OR NOT YOUR IDEAS ARE PRACTICABLE (REASONS WHY AND SO FORTH) AND WILL, ON REQUEST, SUBMIT A SCALE DRAWING FOR APPROVAL ON RECEIPT OF DEPOSIT.

NOTE: IN CONSIDERING THE DESIGNS DRAWN ABOVE IT SHOULD BE BORNE IN MIND THAT IN FRAMES OF UNEQUAL ANGLES THE TOP TUBE LENGTH VARIES WITH THE FRAME SIZE.
