Corrections & Additional Information

Photo caption facing page i - Correct date is 1991.

Page iii, paragraph 4, line 6 and page 328 - Correct spelling is Csaba Sajo.

Page 2, paragraph 1, last sentence - David Duffield points out that Hercules was already part of the Tube Investments group at this time. In 1960 TI took over Raleigh and gave them control of  TI's cycle manufacturing interests, which also included Phillips. Hence the last sentence of paragraph 1 should read: "Raleigh was soon to be absorbed into the Tube Investments group, of which Hercules was already a part."

Page 15, paragraph 3, line 3 - Delete "of his Y-frame bike".

Page 23, lower diagram caption - Jem Kime correctly suggests that this should read "companion focus on node for split".

Page 33, lower photo caption - Correct spelling is Baswell.

Page 35, paragraph 1, last sentence - Paul Cooper recalls that the rare and original amber-wall version of this 16 x 1 ¼" tyre was shown on S-range Moultons at the 1964 Cycle Show at Earls Court, London.

Page 35, paragraph 4, line 5 - Insert "of" after "performance".

Page 36, paragraph 3, second sentence - Another mystery solved - the difference in wear rates was because Colin used the Dunlop 16 x 1 3/8" tyre, not the 1¼". This is not mentioned in "Half Way Round" but was discovered by Paul Cooper in Peter Knottley's article "Having Another Go" which appeared in Cycling, 6 June 1970.

Page 63, paragraph 4, line 3- Should read "approximately 1¼ cubic feet".

Page 134, paragraph 5 and passim - "Protec" is spelled "Protex" on the Wolber packaging. The spelling used in the book is that originally used by Alex Moulton Bicycles and confirmed by their leading UK distributor.

Page 156, paragraph 1, line 5 - Should read "1½ degrees".

Page 171, paragraph 5, last sentence - This statement is incorrect in theory but defensible in practice and in the light of experience. However, you should bear in mind product warranty conditions and the disclaimer at the beginning of this book.
For a given gear in inches, the torque in the hub gear of a small-wheeled bicycle is lower than in a big wheel - by approximately 1.6 times for the 17" wheel and 1.4 times for 20". However, for a given input force at the pedal, and given chainwheel/sprocket ratio, the torque in the hub is the same, regardless of wheel size - but the resulting gear is lower by the same factors as above.
Therefore for Sturmey-Archer's recommended 2:1 maximum chainwheel/sprocket ratio, the lowest gear achievable with a five-speed hub is about 36" for a 27" wheel, 27" for a 20" wheel and 23" for a 17" wheel. But lower gears than these have been used successfully with hub-geared small-wheelers - as low as 14". With such low gears, potentially damaging high torque levels are unlikely because the rider will probably be sitting back lightly "twiddling", rather than standing on the pedals.
Incidentally, Sturmey-Archer's introduction of the 2:1 maximum chainwheel/sprocket ratio appears to have been forced on them by the problems encountered with the ill-fated 5-Star hub, which turned out to be uncharacteristically fragile.

Page 202, paragraph 4, line 4 - Should read "11 to 18 teeth".

Page 222, last line of caption - Should read "IHPVA News".

Page 258, paragraph 4 - Dave Westwood started his ride on a Hetchins but, because of its poor handling when laden, changed to the AM when he reached the Midlands.

Page 264, paragraph 4, last sentence - Should read "Into these he".

Page 280, paragraph 1, line 1 - Delete second "the".

Page 292 - Photo reproduced courtesy of Mike Hessey, who holds the copyright.

Page 296 - An excellent set of updated instructions for servicing the front suspension is now available from Pashley (address on page 304).

Page 300 - Another useful tip: On some older AMs the seatpin may become loose, even with the seatbolt at maximum tightness. This can be caused by the seatbolt eyelets bending out of parallel. The problem can be solved by inserting a washer (typically about 1.5mm thick) in the slot between the eyelets to keep them parallel. Thanks to Ralf Grosser for highlighting this.

Page 301- In the gear table the multiplication factor for gear 1 of the F&S 3-speed should be 0.73. However, the difference if you use the figure printed is miniscule.

Page 333- The cartoon is by Ron Shepherd (see pages 252 & 253) who imported the first AM into Australia.
