Wrench Science Inc.

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.

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 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 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!

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!!!

Charlie Z and team overcame a lot of challenges to spec, obtain, deliver a Basso Palta for me kitted out w/ very nice components, and it's a wonderful riding machine. The positive experience and the willingness of the WS team to work with me and overcome US distributor issues left a strong impression. I returned to WS more recently - again w/ Charlie Z - on a Time ADHX 45 build, again with some pretty unusual specs and parts. He is remarkably informed, a great communicator, and a real 'partner' helping me sort options to deliver the bike and riding experience I am looking for. The most reassuring aspect of the buying experience is knowing Charlie and the WS team make good on their commitments, resolve any issues immediately, and genuinely care about the outcome. For anything exotic/unusual, these guys 100% know what they are doing. There are very few industry players still able and willing to do 'from scratch' builds...these guys occupy an essential maket niche and they deserve high praise.

It is really the shop you should consider. Biggest kudos to Charlie, Fernando and every other members in Wrench Science whoever worked on my bike with their excellent service.

The ordering process is simple and easy. With the live chat online, I can easily chat with a real person. Charlie always keep me up to date on the status of my bike. They are very responsive and transparent in the entire process. I can easily reach them by online live chat, email, and even by phone to check out the status.

After receiving my bike, I was so pleased. The bike was carefully packed and excellent built. It was also perferectly set up and adjusted. I just simply put the saddle, handlebar, paddles and wheels on, then I am able to enjoy my ride without any issue.

It is my first time purchasing a bike online. I was quite hesitant at beginning and had some doubts. After the excellent experience, WS is the shop I trust.

I bought an Alchemy Chiron through Wrench Science a few months ago. Excellent build, fit, and dedicated customer service. The folks at Alchemy were superbly helpful as well. I couldn't be happier with the bike.

My first bike build and I had a great experience. Staff is knowledgeable and communicates well.

Charlie is very helpful and informative would highly recommend!

I have been riding seriously for about 12 years. I was looking for a store to purchase my "dream" bike from. I looked into local bike shops as well as online stores. I came across Wrench Science during my search and am so happy I did. The entire process has been great. I worked with Tim Medina, who is the founder. I was nervous about getting the right size frame and the right fit, but using the data from a prior bike fit, Tim dialed it in down to the last millimeter. He was able to configure the the bike wth the right length stem, spacers etc. so I would be off and running as soon as I took shipment. He also was spot on with his advice about handlebars, stem, wheels and even water bottle cages. The bike arrived on time and was built up perfectly.
Tim handled all my neurotic and phone calls throughout the process. He clearly is very experienced and knowledgeable. The price was extremely competitive for a bike and build of this caliber. Shipping was free as well.
I like the fact that in addition to being an online bike shop for serious cyclists, they also have an actual brick and mortar store.
So, if you are a bike racer or just a serious enthusiast like me, definitely give Wrench Science a call.

Fernando and Wrench Science are a top notch company. They gave me a great deal on an awesome build and provided great customer service. I had an unexpected injury and they gave me many options to work with the build that I set up. I would recommend them all day!

Wrench science an Charlie Zimmerman rock!!..very knowlegdeable an delivered my colnago v4rs dream bike!!...contact them an get started today to get your dream bike!!

I had the most pleasant experience at wrench science, i got my bike on Friday and it worked flawlessly. The buying experience was awesome and i will recommend this place to whoever ask me where to buy a bike.

If your looking for that Dream Bike build beyond the main bike shops and brands , Tim Medina and team at Wrench Science are your next stop . They are humble folks with a ton of experience on the best bikes, I dealt with Tim himself who is the owner on my Colnago build , he helped all the way through the build process to the logistcs of shipping . It was a very customer orientated process, you know by talking with Tim that his passion for bikes enables his knowlege and expertise.He edcuated me on the Colnago background and Ernesto's journey , the whole thing was an experience beyond just purchasing good's or services , Tim and Team , thank you again for all your help . The bike is magical and worth evey dollar spent , cheers !

What a delightful experience it is to visit Wrench Science. Fernando was incredibly quick in getting my new frame over to California, and I couldn’t be happier with it. This is a family business, full of cycling history and joy for the sport. Highly recommended!

The guys at wrench science were very helpful in technical assistance and offered graces that may have gone overlooked at competitive outlets. Charlie Z is highly reccomended. Great place to manage a complex build.

The scariest part of ordering a bike online is finding the right bike with the right fit. The folks at Wrench Science did a tremendous job helping me find my dream bike and I couldn't be happier with this purchase!

Got a Devinci from these guys. Literally arrived weeks sooner than expected. Very happy with the overall buying experience. With how backed up all bike manufacturers are, I wasn't sure if I would be able to get a new bike for the summer. I spoke with Charlie over the phone and told him what I was looking for in a bike - the spec list, geometry, riding locations, what bikes I was currently considering. He had good knowledge on all the bike characteristics they offered, and took into account my buying timeline to help me find a good fit. I just took my first ride on the new rig yesterday and I couldn't be more stoked!

I explained to Alex what kind of bike I wanted and $14000 later I’m still thinking not one cent wasted. The place to come for your dream bike build. Now off to ignore my responsibilities and ride my bike 🚴

Bought a bike from them in June. I could not find the brand I wanted at any of the shops in my city.

It was delivered perfectly. Very easy to put everything together. Grease was already on everything and carbon paste was provided. 2,000 miles later, bike is amazing.

Highly recommend buying from them, especially if you are looking for a higher end bike. If I ever buy one again, I will definitely buy from them.
