How do they compare to the like and where’s best to buy?

Yup! i’m happy with mine. Frames sizing is a bit on the small size. My medium is 17′ and larges are 18′. not much in it really.
For the best experience deal with Pace direct 🙂

I have one built as a single speed with pace rigid forks – it’s a lovely bike – no regrets

Yes one here too.
Love it. Nice long top tube, short seat & headtube’s, very comfy springy steel ride, bought mine for winter single speeding, 120mm fork up front.
Bought mine in the sales for £499 & it was found to have a small chip under the seat stay so got a new Thomson post included too.
