Comparing these two chains, the new one on the left, my old chain stretched prolly 1.5 chainlinks. Doesn't seem a lot but after I rode with the new chain on ... I should have done it months earlier.
Here are a bunch of my chainrings I've gone through. Initially I started on 44-15 for the Irvine hills (the bottom chainring). Then switched to 48-17 (the chainring on the top right). Now I shall be rocking the 49t chainring (top left) with 2 fixed cogs I can flop on my Mack Hubs.
Officially on 49-17 with the option of 49-15
I changed ratios on 10.14.2011 and the thing I can say now is that man 49-17 is such a fast ratio especially on clipless pedals. I have yet to try 49-15 clipless but I am fine tuning my pedals until then.
Ride 3:
11.9 miles || avg 15.6 || max 25.4mph || total 50.18 miles
I took it easy this ride. I consider this a recovery ride.
