    I found Stage 21 on Google maps and brought my 2020 Tarmac in for service. The next day on my ride, I noticed how great my shifting was. After that, my Tarmac broke a spoke and they repaired my rim and had it back to me in two days. So I decided to build my dream bike and let S21 do it. Mike was simply amazing. I built a 2024 Specialized Allez Sprint with SRAM Rival AXS eTap and DTSWISS Aero Alloy wheels. To save money, he had a new Vision carbon aero bar and a Fabric saddle laying on a shelf that he practically gave me for free to get them gone. He could have sold me some full price bars and saddle. But he is a great shop owner and knows how to get customers coming back. I can't tell you how amazing this build turned out. I have come in three times for little adjustments and they have been perfect. Heck, i even dropped my chain on my first ride and brought it to him to check the adjustments. I know SRAM are notorious for dropping. When I came back, he installed a K-Edge Chain Dropper and almost wasn't going to charge me. I haven't dropped a chain since. I do all the regular maint. on my bikes, but I wont go anywhere else for supplies, parts or trickier service. I do all the work on my girlfriends Ruby S-WORKS but I may take it here for a good going over before our big century ride on October. In conclusion, go see Mike at S-21 !

    Cannondale Spidering, loved the metallic green padded envelope.

    Recently got back into bike riding and found how quickly you need to get your bike dialed back in…read moreafter so many miles. I was referred to OCBG from a friend who worked across the street and couldn't be happier. Cory helped me out with both of my bikes and was very nice and friendly. I took out my bike for a long ride after getting cleaned up and it rode AMAZINGLY. These guys rock and is definitely the go-to shop for bike repairs and services. Thanks for being so generous and accommodating. I will be returning for regular tune ups.

    Watching GCN and other cycling YouTube videos, I've often heard the term "legendary bike mechanic"…read moreused from time to time, and I always wondered what that truly encompassed. I recently took the Park Tool class with Cory, and now I have a better understanding of what a bike mechanic legend is. His extensive bicycle knowledge was very apparent as soon as I saw him tinkering with bikes or my bike for that matter. I am extremely grateful that I didn't procrastinate or pass on taking the course. It was a fantastic experience and I was able to swap and upgrade parts on my bike "myself"--with Cory's support. I am honored I was able to do this with assistance from Cory. Since then, I have decided that, as long as circumstances allow, I will always take my bikes to their shop for servicing. I highly recommend both the course and their shop to anyone. You will not regret it.

    My fiance and I loved coming here- he was wanting to buy a commuter bike and the guys here were so…read morehelpful. He gave them a price range and they adjusted the different bikes. He got to try them out and ride around the parking lot (he showed his license!) and picked up a bike. I don't need wheels YET, but once I do, I know where to go.

    "TOTAL SCAM - Damaged my bike and charged more than advertised -- very disappointing experience"…read more I normally don't leave negative reviews, but this experience needs to be shared. 1. Bike was returned with damage After picking up my e-bike, I noticed a deep scratch on the frame and marks on the Shimano Altus derailleur. It also appeared that someone attempted to cover up the scratch with paint instead of informing me. When I raised the issue, they denied responsibility. 2. Pricing does not match their website Their website clearly lists $30 per brake adjustment. I had both front and rear brakes adjusted, so the expected total should have been $60. However, I was initially told to pay $40 per brake ($80 total). Only after I showed them their own website pricing did they reduce the price by $10, and I ended up paying $70. The receipt reflects this "discount," which only happened after I pointed out the discrepancy. Even then, the final price was still higher than what is advertised. 3. Lack of transparency and accountability Between the unexplained damage and inconsistent pricing, this experience felt dishonest and unprofessional. I have documentation (website screenshot and receipt) to support this. I would recommend others double-check pricing in advance and inspect their bike carefully before leaving. **Update after owner response:** After reading the owner's reply, I want to clarify several key points for accuracy and transparency. First, the owner described my bike as a "one-year-old used bike," which is incorrect. I have proof of purchase from late December 2025 showing it was purchased brand new. I will be uploading documentation to support this. Misrepresenting a customer's property in a public response is concerning. Second, the claim that external parties (Beeline and Rad Power) concluded no damage was caused is presented without any supporting documentation. In contrast, I have maintained photo evidence and receipts. Readers can draw their own conclusions when only one side provides verifiable proof. Third, regarding pricing: regardless of internal explanations about brake types, the publicly listed pricing does not match what was initially quoted. The adjustment to the final bill only occurred after I referenced their website, and even then, the total remained inconsistent with advertised rates. Customers should be aware of this discrepancy and confirm all pricing clearly in writing before authorizing any work. It is also worth noting that the business now operates from a different type of location compared to its previous retail storefront. The current address appears to be within an industrial/business park rather than a traditional customer-facing retail shop. While this may be a business decision, customers may want to do additional due diligence regarding service scope, pricing structure, and business credentials before proceeding. At this point, the combination of inconsistent statements, lack of verifiable supporting evidence, and pricing discrepancies speaks for itself. I would strongly encourage anyone considering this shop to document their bike condition thoroughly before service and to confirm all pricing in writing in advance. For transparency, I have taken screenshots of the owner's response to preserve the original context in case any edits are made later. **Based on my experience, I would not feel comfortable returning.**

They gave me educational advices that were succinct and delivered in a very personable manner. I am very much a beginner to the world of road bicycles and even though I went for the Madone, I was not made to feel ashamed and they assisted me a non-condescending manner. I left the store with not only a new bicycle that I love, but a sharper mind and a newfound appreciation for the hobby of cycling. Once again, thank you to Eric and Bryce for taking all the time with me, even though it was bordering on closing hour. Throughout my extensive interaction with them, I can confidently say their goal was not to make a sale, but to equip me with the most informed decision. The purchase was big, but I made it with no regrets. I have been to many other establishments before coming here, and other bicycle shops NEED to learn from TREK Tustin!
