ECHO frames

ECHO Control frame.

The lightest 26" frame we have ever made.

weight	size short	size long
silver polish	1590g	1630g
white painting	1640g	1680g

Geometry by using a ECHO SL 26" fork (400mm /45mm) when chain is tighten:

geometry	Control short	Control long
wheel base	1065mm	1090mm
BB high	30mm	30mm
head tube length	120mm	120mm
frame space	135mm	135mm
chain stays length	377mm	377mm
head tube angle	72degreed	72degreed

The integrated tensioner is not new for track bikes, we just make it by CNC aluminum for trials. The good side fof this design is the wheel will be sure fixed in the place, don't need any other tensioner for weight saving. The poor side is you must have a allen key to loose the bolt when you want to remove the wheel off .

We also use double butted tubes for this frame to make it lighter.

ECHO Team frame

Just like the Control frames, the new Team frames are the lightest 20" frame we have ever made. By new design CNC parts and double butted tubes.
