GU 20" Frame

- Newly updated frame from Echo brand GU as found on their complete bikes.
- 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.
- Now featuring a 1 1/8" - 1.5" tapered headtube for a stiffer, stronger front end.
- Large hole machined out of headtube reduces weight.
- Uses Echo's Integrated Tapered Headset (sold separately) which reduces weight and stack height.
- Top and down tube gussets at the head tube add stiffness and improve frame life.
- Integrated brake booster and brake mounts are machined from a single piece of aluminum which improves braking power.
- Features dedicated 4-bolt mounts spaced at 99mm.
- Uses M6 brake clamp bolts instead of the traditional M5 for additional stiffness (clamps sold separately).
- Standard 8mm thick CNC machined IS disc mount.
- Reinforcement between the chainstay and seatstay provides additional disc mount strength.
- Includes Echo's Mini Bashplate to protect the freewheel.
- Available in an anodized red finish with laser-etched GU graphics.
- Frame supplied with steel bottom bracket installed.
