The ride felt sluggish and I never felt like I had a good spin, maybe due to the added mass in the extra chain links and larger ring/cog? I'm not sure, anyway if you have input that would be great.
Thanks
Something is amiss here.
With 700 x 28c
46 x 17 = 72.4 GI
46 x 18 = 68.4 GI
50 x 20 = 66.9 GI
That's a significant difference and you
should feel the difference.
The odd thing is, the 50 x 20 should have been much easier to spin, not harder. Almost 8% easier.
