MKE just got in their first batch of Reynolds 853 / 520 29’r frames.
“All frame purchases include a multi-speed derailleur hanger dropout whether you choose to have additional cable stops or not. That way if you don’t have the optional derailleur cable stops installed you can still run a 1×9 later with full housing form shifter to derailleur.”
