[QUOTE="BigEd, post: 109152, member: 161"] When my brother John was racing my rigid Sunbeam we ran 19" wheels with Avon GP tyres with pressures at 18-19 psi, far lower than any tyre manufacturer would recommend. The friction dampers on the Druid girders were tightened so that they would only just move on a large bump. The suspension then came mostly from the tyres themselves. On most UK tracks there are not many sharp bumps. I'm not suggesting that this will work for every rigid bike but it worked for us and could be a guide for others using similar old machinery. Lots of suspension travel is great but only if you can control it with adequate (i.e. modern hydraulic technology) damping, preferably two way. I think I may have posted something similar before and although it not really specific to this "Series B Versus Series C" it bears repeating with relation to Mervy's suggestion. [/QUOTE]
