Highlights
Quality
Works perfectly with my diamondback 700c, easy to install and great finish

Price
Works great for a realitvly cheap price point.
Great set of cranks especially for the price!
With the price of bike parts being what they are this is a good value.
I didn’t want to pay more for the replacement crank than i did for the old bike.
Shipping
It was delivered very quickly and was easy to install.
It took 6 weeks for the crankset to arrive.
Was supposed to be shipped to the store, but was shipped to the house.
Got it a couple of days a go, installed it yesterday but can't wait to go for a ride.
Packaging/appearance
”so i looked in the box, it was inside a flap that secured the gears from sliding around.
Competitiveness
I added it to a cheap bike as an upgrade to a bike that already had shimano tourney running gear that i ride as a hybrid/commuter bike.
I also went with a 170 instead of 175 crank arm which i like a lot better.
