Cake hmm this could be close my bike is 25 years (age corrected after a chat with my Dad who bought it) old so how second hand was yours when you got it? I also made the front wheel all by myself age 13.
People who know a bit about these things tell me it's too small but when I measured it I make it a 52cm frame which is way too big for little 5ft 3 me. So we shall see, I do get a little lower back ache over 35 miles but it could well be a case of I just need to get used to doing more miles.
I'm reading Iron War at the moment, finding it very interesting.
Nurse - Hope your a bit more mobile today.
Slow and steady 5 mile run this morning for me, feeling much better for it.
