I have a Raleigh Stuntman and a Diamondback Sync'r Pro. Both are well designed bikes with excellent performance. I'd put the Sync'r Pro up against any alloy hardtail sold for twice the money from a major brand, the geometry is dead on, the bike is tank-like in its toughness and the components are all top notch. The Stuntman is a completely unique and useful bike that is exactly on point in today's gravel/adventure market. I've seen tons of custom, extremely expensive and "cool" bikes that mirror what the Stuntman already offers off the shelf.
Too bad neither bike is still sold...
Also notable, both of my bikes have proven to be very reliable despite my abuse.
