Hello Elaine.
I'm a shorty and had to look around for nearly a year before I found a decent secondhand road bike locally.
Eventually found one that fitted in Harry Ingham's, opposite Morrisons in Tod. The shop is very old fashioned, Harry is 'getting on a bit', but is very, very helpful. Cheap too 🙂
Alternatively, have a look in the Cycle/Recycle place in Hebden on the banks of the canal, where the alternative technology centre is. Run by a very pleasant chap called Ben, who will keep an eye out for a suitable frame and bits for you – it's a great place, full of interesting bits and bobs and well worth a visit.
Vale cycles in Tod, opposite the college, sell secondhand road bikes
occaisionally, might be worth having a word.
Blazing Saddles in Hebden would be worth speaking to as well – they generally know what's for sale locally.
Last one I can think of is the bike shop in Mytholmroyd, on the left on the way up to Cragg Vale – they very occaisionally have secondhand road bikes in, but they tend to sell quickly.
Good luck!
