## Features

- QUALITY CYCLING PRODUCTS SINCE 1985: Our Italian designed cycling shoes, bicycle, and cycling products have made riders look like pros since '85. But we're more than just fancy gear, we're a community. Our cycling-crazed customer service team in Denver can help with any questions or concerns. Plus, our Lifetime Warranty Replacement Promise means you can put our gear to the test with unrelenting confidence. We hope that you will Join The Ride, for fun, fitness, and community.
- THIS IS NOT A BEGINNER BIKE: The Siena is a top-performing bike that's not just for beginners. Gravel bikes can be intimidating, but we believe that new riders deserve bikes that deliver affordable performance without compromising on quality. That's why we recommend the Siena for new riders who are serious about their cycling goals. Unlike other so-called "beginner bikes" that are quickly outgrown, the Siena comes packed with high-quality components typically found on higher end bikes.
- UNLEASH YOUR ADVENTUROUS SIDE: The Siena is the ultimate off-road experience, with 700x40c tires, designed to conquer any terrain with unwavering stability and versatility. To withstand the harshest challenges, we use the unstoppable TC-20D rims, with the durability of 28 spokes, ensuring a smooth ride that smashes any terrain. When it comes to stopping power, the Avid BB5 disc brakes have you covered, providing the additional stopping force needed to tame any weather or trail condition.
- NEVER MISS A SHIFT: Shimano Tourney shifters provide consistent, reliable shifting in all riding conditions, so you can focus on pushing yourself. Unlike our competitors, who cut corners and use off-brand parts to save money, we use a 100% Shimano drivetrain. Why? Because Shimano makes the best drivetrain on the planet, and they're at their best when used together as a complete set. Please note that professional assembly is required to validate your warranty and ensure optimal performance
- BUILT TO LAST: All too often things are made cheaply and break before their time. We believe that bikes should be reliable and built to last. This is why we use premium aluminum in our frames, and back it with our industry leading lifetime warranty. We use only Shimano components, which are backed by Shimano’s two year warranty and function better than competitors. Ride with confidence! PLEASE NOTE: ALL BIKES ON AMAZON COME UN-TUNED. PROFESSIONAL ASSEMBLY REQUIRED TO VALIDATE WARRANTIES!

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great bike
*by D***T on January 5, 2019*

After receiving my well packed bike in a huge box, I went to unpacking it as fast as I could. I found no defects or issues. The bike went together very easily and without problems. After tuning the bike and adjust it for size, I took it for a ride around the block. I was amazed. The bike made no noise while riding at all, unlike my old mtn bike it was replacing. I shifted through the gears and was soon at top speed, what a rush. Braking was good also. My only small complaint is that shifting is a little slow, but other than that, it’s all good. I’m already looking at tommaso bikes for when I want to upgrade to a full road bike in a year or so.

### ⭐⭐⭐⭐⭐ This is the best value and most versatile of all of my 8 bikes!
*by B***. on March 1, 2021*

Wow! What a surprise. This is an outstanding gravel bike for half the price of a Canyon entry-level Grail Trek or Cannondale (and there would be a six month back order) The Shimano Touray group set with a tripple cage is as good, but perhaps heavier than a 105 or even an Ultegra. It's not even all that heavy. If I didn't have so many bikes, I might have upgraded to a carbon fork. Be careful on the sizes, however. The stack is accurate. The reach is really too long for a 53 cm and is about the same as my 56 cm. You might need a shorter stem to compensate, Nevertheless, the best value and quick delivery out there. Get this bike!

### ⭐ Not so great
*by H***S on October 30, 2019*

Below average quality, beautiful but not a great bike purchase the bike on September 2019 ; one of my spoke pull off after ruding it for 500km all attempt to get Chris CRM at Tomasso to attend to this problem fell on deaf hears. I replace the tires to gator skin 700x32c road bike tires and trill began . It became a very fast bike and I love it
