I have two Merlin MR29 chassis for sale. The 2011 has the larger brake caliper and the 2012 has the mini caliper. Both have 50mm axles, fully adjustable caster camber pills top and bottom, removable front bar, tillet seats but no gauge. They are being sold as rollers with douglas magnesium wheels. Asking $1200 each. Need to sell this is a great price.
