I have a brand new 2010 GF Paragon with external bearings and the Shimano crank that comes with it.
When I am in the biggest cog in the front, and the 2nd smallest cog in the rear, I can feel an odd bumpy/grinding feeling in the crank while pedaling. The grinding does not feel gritty. My first assumption was the pedals, but I can put the bike in the stand and push the crank without touching the pedals, and I still notice it. It is more pronounced when I am riding the bike in this gear.
Could this be the bearings? or something else? I confirmed that the chain is not hitting the derailleur.
Please let me know if you have any ideas. Thanks.
