Re:
I just measured the seat to bar drop on my Rourke and it is 120mm and I don't ride with a particularly flat back.
Planet X and Ribble always have deals on tyres. I like Michelin Pro4 service course, also Vittoria Rubino Pro, which are as cheap as chips but which I find work well for me.
Good looking bike though, with a bit of fine tuning it should be a corker.
