Here you can see how Nashbar and Universal Cycles match up head-to-head in a battle for the Best Bicycle Part Stores in 2025.
Nashbar's been a go-to for cyclists since 1974, now under AMain (the same parent company as Performance Bicycle). The site is easy to shop, prices are fair, and the selection is deep across all categories of bike parts. Returns are straightforward, and customer reviews are excellent. Although the selection here is a little smaller than its sister store, and there's not much in the way of rider guides or DIY resources, Nashbar still crosses the finish line in a respectable position among the competitors on our list.
Universal Cycles has a massive catalog and a flagship Oregon retail store, but shopping here comes with too many headaches. The website makes comparison shopping difficult, shipping isn't very competitive, and the return policy is stricter than most rivals. Customer feedback is mixed, and while the BBB shows an "A+" rating, you'll find just as many complaints about slow service and denied returns as you will praise for fast responses. Overall, it's better to choose a higher-ranked bike parts shop.
If you love to ride, your bike isn't just a set of wheels - it's freedom, a workout, a weekend escape, and sometimes the way you get to work. Like any machine that racks up miles, it needs regular care to stay smooth and reliable. Whether you're cruising the neighborhood, shredding mountain trails, or hammering the road in pursuit of a personal best, the parts are what keep you moving - quite literally. Build a simple routine of checking your chain, brakes, and tire pressure to catch problems early and keep the stoke high.
The parts riders buy most often are the ones that wear out fastest: tires and tubes, brake pads, and chains - components that can make or break a ride when they're past their prime. Once the basics are handled, plenty of cyclists chase comfort or performance with a lighter crankset, a more ergonomic saddle, or bright, high-visibility lights for safer nights. It's also common to stock up on everyday items like grips or bar tape, pedals, and derailleurs, especially when a DIY repair is on the weekend to-do list. Then comes the fun part: personalizing the bike with anodized accents for a pop of color or swapping in carbon fiber pieces to shave a few ounces. Before you hit checkout, it's smart to confirm compatibility with your frame and drivetrain so your new kit fits and performs the way you expect.
Shopping for bike parts online can genuinely change the game, especially when you're chasing down components your local shop doesn't stock. With a much broader selection, it's easier to dial in the exact fit and style you want, compare brands and specs at a glance, and lean on real rider reviews - all while finding prices that are often better than in-store. Most retailers back that up with fit guides, sizing charts, and live chat, so you can buy confidently without lugging your bike across town. If you ride a lot, stocking up on consumables like tubes or a spare chain saves both time and money over the long haul. As a bonus, many shops now offer quick shipping and flexible returns, which makes fixing a mismatch pretty painless.
Of course, not all online bike part retailers are created equal. Before you load up your cart, here are some good criteria to keep in mind when deciding where to shop:
Whether you're replacing worn-out parts, upgrading your bike for better performance, or just grabbing a spare or two for your gear stash, the right bike parts store can make all the difference. That's where we come in: the team at Top Consumer Reviews has done the research to review and rank some of today's most popular bike parts stores, so you can skip the guesswork and get back to riding. Happy trails!
