Have a Streetmachine GTE recumbent. It has a Torch rear shock with a 550lb rear spring on it. I am near to bottoming it out, being lardy, so can I get a stronger (8 to 900lb) spring for it and, if so, where?
Eyelets of the shock are 150mm apart and that is all I know. Think it's made by DNM but their website doesn't give any springy stuff on there.
Bike is rated to 120kg with that shock but I weigh 114 plus camping luggage!!!!!!
At the pace of sailing ships and bicycles.
