Sour Bikes Crumble XL Frame in Jamaican Ice Black. This is an ex display frame that has been built up and dismantled. There is a very small paint chip under the chain guide mount, so you can only see it if the bike is upside down. This will build up to a perfect trail bike for UK conditions with 2.5 tyre clearance and 120-140mm suspension forks. This is for frame only.. RRP £1049.00
