So I was cleaning up my garage this afternoon and the biggest mess was my dumping gound for cycling stuff I'm not using or haven't used for quite awhile. I found a set of extralite octaramp chainrings (now on ebay) and another 50t extralite ring. There was also an old salsa 34t ring, both being 110bcd. This got me to thinking - my computrainer bike has an old shimano rsx (or is it rxs) crankset w/ 46/36/26 rings, which doesn't help my winter training when my regular bike has 50/34. Fortunately I still have a crank puller, popped the drive side off and attempted to take off the rings. The 26 came off no problem. The bolts for the other 2 rings would not budge- all steel and the stupid nuts are not hex nor torx, so they were just not moving. DRILL! I have a set of drill bits from my (late) uncle- the made in the USA type from the 60's-70's. Nothing stops them.
The cordless drills were not cutting it, so I went for the electric drill. Noise, smoke, hot metal shards and 10 minutes later I had those rings off! Ah, sometimes destroying things is just plain fun!
So, my circa 1990 steel touring frame is now set up w/ an rsx crankset w/ a 50t extralite ring on it. It's now 50/34. Shifting w/ downtube shifters (friction on the FD) is quite nice, compared to normal shifting w/ extralite rings!
Words are like bullets, I let them pass through me.
