- New from Extention, the Rise 20" complete bike!
- Designed to compete with some of the most popular competition 20" bikes, the Rise 20 features modern geometry, a great spec list and high quality finish.
- Hydra formed aluminium frame uses a tapered head tube for increased front end stiffness.
- Unique closed drop-outs for M6 hubs reduce stress risers in this area, providing greater stiffness to counteract disc brake forces.
- 160mm post mounts as standard make brake alignment and adjustment easy!
- Neat roller tensioner provides excellent chain wrap and tucks away under the drive side chain stay to prevent accidental damage.
- Extention 7075 alloy, external BB cranks use a 24mm steel spindle and 2 piece design, much like Hollowtech Shimano cranks. This results in a super stiff pedal interface!
- Extention sealed bearing hubs laced onto Extention comp rims make for a reliable and competitively light wheel set.
- The Rise 20 is supplied with a sloped stem and Carbon sloping top cap wedge. You can run the stem as it is or we can cut the steerer at an angle when you purchase the 'alloy fork with sloping stem' cutting service here.

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.
