I have had an old bike in bits for about 20 years that I got it out of the garden shed today . I think it is a Raleigh Hercules Hustler that I bought second hand circa 1990 after my "best bike" had been stolen . However I never used it much so did not build up any detailed knowlwdge about it . Today , when I removed the old tyres , I realized that the 2 wheel sizes (front and rear) are different which does not make sense to me : the wheel sizes on the old tyres say it is 26inch by 1 1/4 and 27inch by 1 1/4 ! ( so it is well on the way to a penny farthing!) It also has Derailleur gears fitted. How do the brakes fit with odd sized wheels?. And according to the Raleigh catalogue of 1971 it should have 26 inch wheels and a Sturmey Archer gear set up. Any advice on what to do next would be appreciated.
