A few tiny tricks I do to my bike.

For the left lower leg of the sub-frame,I bought a 2x6 galvanized joist hanger and cut one side off,it's an 1/8" thick,perfectly pre-bent 90 degrees...and pre-drilled.All I had to do was drill a few pilot holes in the frame.Then coated the threads of some self tappers with black RTV,ran a good bead of RTV the length of the hanger on both contact sides of the hanger and frame to help keep out water/moisture,and gently seated the self tappers with a cordless drill.



My subframe was really beat up when I got the bike. The p/o had a JUNK roller chain installed, and stretched floppy roller chains probably are what trash the inner sub frame. Now that i run a top shelf Regina ORN oring and keep the chain tension in spec, even my teflon pad has only slight scratches.




As you can see,there's hardly a scratch on it,and it's been on for just about a year.At this rate,it should last me the life I own the bike.

Yeah,that's how mine was too when I got it...it had a D.I.D X-ring that was more played-out than most of the women I've been with!.I'm with you on the Reginas,they've been my choice of chain since the early 90s...but when I started having issues with the case getting chewed up,I did some research on different chains.Part of the problem was it had a spanked 14T Sunstar front and the collar inside the shaft spline was worn,so it enabled the sprocket to woble a bit.So I replaced the o-ring,the collar,the C-clip,and put a new Renthal 14T on...the way the Renthal was designed/machined brought it out away from the case a little more than the Sunstar.Now for the chain,I ended up going with an RK-MXU-ring.....I know,NOT my favorite choice at all,but....it has a 9000lb tensile strength,which is good since my left hand suffers from a disease called "Groping the clutch too much"...where as the Regina was about a respectable 8400lbs,and the MXU is far narrower than any other O-ring I've seen and lighter at about 3.3 pounds.....and I gotta say,I've had it on there for roughly 8 months and only had to re-adjust it once after the 1st ride.I can honestly say,I'm impressed with RK for once.
