Hi all Rail users, I have covered many miles in the last few months mainly muddy trails around the ridgeway but also number of dusty and sandy runs over at woburn sands. So my problem was muck, dust and debris getting stuck in the gap above the pivot. My worry would be stones and alike getting caught up and doing further damage. After looking on many forums, and testes a few plastic products, I've come up with the following design, that provides flexibility, yet still protects the pivot. Which ridged plastic ones do not seem to do as the leave a gap when the bike flexes for debris to get stuck in still.
