A colleague of mine told me about DP three years ago and said to check out for his custom frames but I didn't think much of it since I was not into steel and couldn't afford it. I didn't know he had cancer and may he RIP but I wanted to see what the hype was all about after he had passed.
I sought out any type of DP bike and found one here from a PL member. I'm 5'10" and ended up buying a 59cm Responsorium Ciavete on a whim. The member said if it did fit then he would refund my money. Fast forward four months later and I couldn't be happier. Yes, it's slighter large but I live in SF and climb these hills w/o any issues.
I've had aluminum and carbon in the past which were fine but I just enjoy the steel when riding these streets. I'm not into racing but just love riding and enjoy the scenery of the best city in the world.
I drank the Kool-aid and think others should too regardless of size
