Wrench Science Inc. 1022 Murray Street, Berkeley, CA 94710

"I've purchased two different bikes over the last 6 months and the service has been great. If you want a truly custom bike and not your typical cookie cutter bike that a typical bike shop has. Then this is the place. No showroom but a great website for you to pick every single part on you bike. A bike lovers dream. Charlie, my associate has been great."

"I am glad that I stumbled on Wrench Science. This is the second high-end carbon road frame I have owned, and I couldn’t be happier. Unlike my first carbon, (that I was very happy with) I was able to customize every aspect of the purchase at no extra cost. Charlie Z at WS suggested that I first have a fit done by Fitted by Pedro in San Francisco. (This is advice well-taken. I have had many bike fits, but none as accurate and effective as Pedro’s. WS covers half the cost.) My Wilier Filante arrived 60 days later, and it is the most comfortable racing bike I have ever ridden. I attribute 50% of that to the bike and 50% to Pedro. Wrench Science gets 100% of my recommendation for putting the two together."

"I’m super happy with the prices, shipping speed, and communication from my sales man Charlie!!!! He came though with this beautiful Argon18 E119 frame, wheels and sram red components much sooner than I expected!!! Thanks!!!! I look forward to competing in Iron Man mussel man this summer on this rocket!!!"

"After years of waiting I finally decided to pull the trigger on a De Rosa. It was not easy to find an authorized dealer until I stumbled upon Wrench Science and i'm thrilled I did. In my case, my frame had to be ordered directly from De Rosa and the wait times were long but Charlie Z. (my sales rep) had me updated all throughout. I changed my mind like 3 times on the build, wheel sets, stems, etc while my frame was in the making and Charlie was always on board. In addition to all that, I was very stubborn to get this specific handlebar which was out of stock at the time and would take much longer than the frame and somehow Charlie got me the one I wanted in time so that was awesome. I'm not much as to leaving reviews but credit is due to Wrench Science and in my case Charlie. I recommend 100%, and will always buy my future bikes from them without a doubt."

"I finally had the opportunity to order my dream bike, and I can’t say enough positive things about the team at Wrench Science. I knew my sizing specs, and I worked with Charlie Z. on ordering everything for my custom build. Charlie is extremely knowledgeable, and he was very consultative and responsive to all my detailed questions throughout the process. I’ve had my bike for a few weeks now, and I’ve logged lots of quality miles, including plenty of climbing. Everything Charlie and I discussed, from fit to performance elements, worked out and became reality. I am 100% stoked with my new bike. Huge thanks to Charlie and the team at WS!"
