Solid value

I ordered the bike for my daughter who wanted a simple, low maintenance, single speed bike. The stock tires measured 23 mm on the calipers, even though they say 28 mm on the side wall. (stock tires are not the greatest.). I ordered a set of Ritchey Alpine JB’s in 30mm with a tan sidewall. They fit great (with a little room to spare) and look awesome! The other short coming on the bike if I’m being honest is the seat which is hard and cheap, so I ordered a comfort saddle off Amazon those two improvements have made the bike near perfect for her. She loves it!! it’s a solid performer in a great value !

Picked up used and is a home run!

I picked up a 2019 model Core line for really really cheap. Sometimes without even trying, I am able to smash my PRs that I made with very expensive carbon fibre bikes like my Roubaix and Domane. I did fit my Core with some drops. I really enjoy riding this bike.

WAY nicer than I expected!

My new Earthstone Core-Line looks and feels much better than I expected! Feels super solid and looks sleek & sultry, and I love the red anodized hubs! It received some minor boo-boos during shipping, but the friendly local mechanic fixed the spoke, rim tape and added some lube where needed. Can't wait for the sun to rise so I can get on it again!

Great deal on a great bike

I scored this bike for under $400 and I couldn’t be more happy. The bike feels like high quality, no issues when shipped as it was secured great. The bike rides smooth and loving the simplicity.

While my opinion on what’s great, good, fair or junk isn’t exactly credible, I can still use my voice as to what is good for me personally. After a new saddle and some (very slight) thicker tires, this baby rides like a fantasy. And for a little under 500$ ( not counting shipping & tax) it’s well worth it. Future buyers will most definitely want to opt for the bigger tires and more comfortable saddle. I paid a little extra for drop bars and upgraded pedals. Bottom line, this machine kills fascists.
