Shimano Tourney FC-A073 Crankset 170mm 7/8-Speed 50/39/30t Riveted

nice upgrade to road bike higher speed in upper gears great power in lower rings;

This work perfect for us on the bike we are well;

Got so much more final speeds with this 50 tooth intead of the original 42 tooth chainring on my Cannondale M300. And it looks so much better. Easy to install using the basic tools for the job acquired from Amazon.
If needed the recommended Shimano Bottom Bracket is UN300 with a Square Taper of 103MM at the Shimano Site Page for the Tourney A073 7/8 speed Triple 30tx39tx50t Cranckset;

I bought this to increase my chainring set from a 24-34-42. I also wanted to increased resistance for a better workout and increase my speed. It was an easy installation. I needed to make a few minor adjustments on my bike and get a new chain to accommodate the larger chain rings. After installation & adjustments it took me a couple weeks to get used to the new cranks but now my average pace got significantly better. I went to from a 4 min. 39 sec./mile pace down to 4 min./mile.;

Got this to replace the crankset on my old Terra Trike Path trike. My original crankset was a single cog 46 tooth chainring and that didn't give me a low enough gear for climbing some hills near my home. I briefly experimented with a 53/39 crankset and that wasn't low enough either. This 50/39/30 gives me a low enough gear to get up the hills. My overall gear-inch range is now 15.5 inches to 85 inches. This seems to be working out pretty good for me so far.;
