Yea man! I've ridden mine several times. Heavy fucker.
I have such inexperience I don’t know the difference between retro heavy or retro super light, But I have held Joe Breeze’s Lightning ‘GT3’ @ 18 lbs with pedals and barends which is just absurd and totally amazing to behold - and hold. If only I could’ve ridden THAT!
I ride my brother-in-law Merlin on occasion. It's around 20lbs or less. Crazy fun to throw it around on some fun XC trails with lots of switchbacks. It really needs an airbag. ;)
Does the seat tube pass through the top lug? All the other tube attachments make sense but still trying to wrap my head around that joint
