I have an older roadrat:
pros
– very fun to ride
– very versatile I have ridden it geared,fixed,singlespeed flat bar, drops, off road, as monster cross bike etc..
– frame “flex” makes for a comfy ride
– looks different to bland road bikes
cons
– Heavy – over 10.5kg even as singlespeed with lightish components.
– handling feels odd at times, but might be because I have drops on the long rat.
– chain tug / mech hanger is a right pain, I really hate it
