Do people have problem with chain grease on the leg? The Rambler photo on the Terratrike website shows the chain exposed behind the chain ring. My tube was up to the chain ring. Recently I discovered the chain cutting the derailleur cable and frame, so I moved the chain tube back to protect the cable and frame. Now the front of the chain is exposed up front and I am getting a big patch of chain grease on my leg, or pants if wearing long pants.
I have a rambler 27 speed with the long size boom. The tube is about 40 inches long. It needs to be at least 4 inches longer to protect both my leg and the frame from the chain.
