Echo Mark IV 26'' Frame (with steel BB)

Description and materials
- New Echo Mark IV 26” frame, the last version of the most popular 26” frame from Asian manufacturer Echo.
- Features a newly designed head tube, that now uses an integrated headset (which does not require a cup) to make it simple, lighter and even more reliable, available here.
 - Spanish-type bottom bracket, which uses press-fit bearings without threads (like the ones used for BMX), so it’s way stronger and stiffer than usual BB’s (Echo ISIS Spanish-type bottom bracket supplied with the frame).
- Its clever design means it keeps the weight down (only weighs 1.43Kg) with a simple, neat design.
- 110mm long head tube, with a CNC-machined window that helps save unnecessary weight.
- The head tube is gusseted to the top and down tubes to increase its strength.
- CNC-machined dropouts spaced at 135mm, designed with the Echo integrated chain tensioning system.
- Features 4-bolt rim brake mounts spaced at 100mm (we recommend using a brake booster).
- CNC-machined BB yoke helps stiffen this critical area.
- Features an integrated chain tensioner, which uses two M5x25mm bolts located inside the dropouts for adjusting the wheel position, so snail cams are no longer needed.
- Note: due to the integrated chain tensioner, this frame has been designed for using a 135mm Echo rear hub. Other hubs can be used too by adding some spacers, so that the spacing is 135mm.
- Anodized silver finish.
