Here I am with another noob moment when I ask for help. This time, it’s about inner tubes. Over the past year, when I need a new inner tube for either of my bikes, I got them directly at the bike store. They looked at the tire and picked it for me. Then I went and ordered some online but they don’t look exactly the same width. Close, but not exactly. Are the new tubes I got online the wrong size? What’s the difference here? What I got at the bike store (which fits): 700x20c-25 (That’s what it says on the side of the physical inner-tube) What I ordered online: 700x20c-25c Race 28 https://www.amazon.com/gp/product/B01M6AUWM8/ref=oh_aui_search_detailpage?ie=UTF8&psc=1 Race 28? They seem slightly narrower. Will they work or should I return them? Thank you in advance for any help you can offer.
