An adjustable aluminium stem extension. It adds roughly 115 mm of reach and can be bent to raise the handlebar by up to 70 mm, so the riding position moves with your child instead of staying where it was on day one.
This is the cheapest way to buy another season out of a bike. A child who has grown out of the reach but not the frame does not need the next size up — they need 45 SGD of stem.
