My father has a RecumbentUSA.com bike, we are unsure of the model, but I'll have pictures later if anyone is wondering. He's had the bike worked on by a LBS a few times and can't quite get it working the way he wants it to. One of the main issues he is having is the chain retention tube is sliding around which allows the chain to drag across the chainstay... it's cutting the stay up, which is bad news. I didn't know about this issue until today so I had him take some pictures so I could ask you guys the PROPER way to fix this issue before it damages his frame any further.
I'm not familiar with recumbent cycles so dealing with a chain this long is a foreign idea to me. I really appreciate any help you could provide. Thank you in advance!
The bike overall.
They way it's currently cobbled together, and the damage.
One last larger photo.
Let me know if there's any other information I need to provide. It's nice to see my father out exercising, but this has me concerned. I'd like to fix it for him right, since it would appear the LBS isn't willing to.
