Rich Can you share the STA, OD and wall thickness of the main tubes and the trail for the Mercian?? Curious as to how they compare to your Rivendells.
I looked at the Mercian 15 years ago and they are very nice frames/forks. The price was good even at the exchange rate then. Might be better with the better exchange rate now John Hawrylak Woodstown NJ On Friday, November 18, 2022 at 9:32:54 AM UTC-5 RichS wrote: > Paul asked about another bike that rides like a Rivendell.
