Super light weight and top-spec complete bike from GU!

- Super light weight and top-spec complete bike from GU!
- New headtube design (110mm long) now makes use of an integrated headset. This is different to an internal headset in that it features no cups. The bearing sits directly inside the frame, saving weight whilst having no effect on performance whatsoever.
- Features the 'Spanish' BB system used on Echo and ZOO! frames which uses a large press-fit bearing - this gives a longer BB life, whilst still using a strong M15 ISIS spindle.
- New splined freewheel interface on the Echo SL cranks makes fitting and removing freewheels much easier than the traditional threaded interface. Freewheel is held in place by an adapted bottom bracket spacer and the pressure of the crank bolts. There is no lockring!
- Integrated chain tensioners - as used on previous Echo and ZOO! frames - help you achieve perfect chain tension whilst being neat, lightweight and out of harms way.
- New, SL rear rim features a custom profile that is both strong and light.
- New Echo carbon handlebars coupled with the CNC machined SL stem provide a fantastic handlebar/stem combination that weighs practically nothing!
- Rear 4-bolt rim brake mounts use an M6 thread rather than the usual M5, reducing the chance of stripped threads and enabling increased clamping force.
- Titanium bolts used throughout, with exception to the front 4-bolt mounts.
- Also fitted with titanium freewheel, sprocket, bottom bracket and pedal axles.
- Now supplied as standard with Maxxis tyres and inner tubes.

All bikes may feature small blemishes in the anodising or marks in the finish of other components - this does not affect your warranty.

This bike is supplied with a 6 month warranty covering manufacturing and materials defects. The warranty does not cover mistreatment or poor maintenance. Please ensure all the details on the warranty sheet supplied with the bike are adhered to. Certain circumstances (such as stripped threads or rounded crank arm tapers) only occur due to a lack of correct maintenance and all manufacturers are aware of these situations, so any claims due to incorrect maintenance procedures are much less likely to be successful.

We build this bike to a 100% complete state in our workshop before dispatch to ensure all items are manufactured correctly and nothing is missing, but we do have to remove some parts to ensure there is no damage during transit. You will need some basic tools (usually 4mm, 5mm, 6mm and 8mm allen keys and a 15mm spanner) for final assembly upon arrival. We have a video guide here to help, but please don't hesitate to contact us if you require any further assistance.
