GU 20" Frame

- The GU 20" frame offers durable, stiff performance.
- Features Echo's press-fit Spanish bottom bracket system which gives a longer bottom bracket life and increased strength.
- CNC machined horizontal dropouts spaced at 116mm give a large weld area for the chain and seat stays, providing added strength.
- Uses Echo's simple and lightweight integrated chain tensioners. Grub screws push against the axle and are tucked out of the way and won't get smashed like a traditional sprung tensioner.
- Large hole machined out of headtube reduces weight.
- Updated with Echo's new Integrated Headset (sold separately) in which the bearings press directly into the frame, reducing weight and stack height.
- Integrated brake booster and 4-bolt brake mounts are machined from a single piece of aluminum which improves braking power.
- 9mm thick IS disc mount is welded to a reinforcing gusset and the seatstay to increase durability.
- Reinforcement between the chainstay and seatstay also improves disc mount strength.
- Top and down tube gussets at the head tube add stiffness and improve frame life.
- Features dedicated 4-bolt mounts spaced at 99mm.
- Uses M6 brake clamp bolts instead of the traditional M5 for additional stiffness. M6 Echo SL brake clamps supplied with frame.
- Available in an anodized purple finish with laser-etched Echo graphics.
- Frame supplied with titanium bottom bracket installed.
