Strengths: Great geometry, very accurate welding and assembling, super cool finishing.
Weaknesses: I' d agree a little shorter chainstay lenght.
I arrived at Tweet Tweet frame after trying several ones around. The geometry similar to Blk Mrkt Riot gave me the kick off.
After noticing the great finish and care to details, i was surprised on how the frame fits me.
Bottom Bracket is at the right height, and from first ride i feel like i was riding it form months.
I would appreciate a little shorter chainstays for trail riding.
The right compromise between rigidity and "softness" tipical of steel.
Also riding it on bmx track gave me good vibes, fast cornering and great feeling on jumps.
