Thank you Ty Two things I had forgotten about bikes of this era were:
1. Q-Factor. These SR Aerox cranks have a Q-Factor of 138mm by my measurements. That's like an inch narrower than most road cranks today. 2. Suntour Symmetric Shifters. These things are so darned clever. I remember as a teenage mechanic working on my Sportour and 'kind of' understanding what they were supposed to do, but now that I have a lot more respect and appreciation for how clever they are. The two friction shiftlevers are mounted on top of the downtube as a single assembly. The two shiftlevers are connected to each other through that assembly. When you shift the right hand shifter, it causes the left hand shifter to slide up or down the downtube. What this gets you is that when set up correctly, the left shifter trims the front derailer automatically for you anytime you shift the right side shifter. So you get a drivetrain where the front derailer has a nice flat narrow cage for super precise shifting, AND the chain never rubs on the front derailer. There's never been another drivetrain where the front derailer trims itself in reaction to a rear shift. It's borderline genius, and I'm really happy to have an example in-use again.

Hadn’t thought about the brand in a really long time. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
