We’re more than fancy gear—we’re a community. Our cycling-focused customer service team in Denver is ready to help with any questions. Our Lifetime Warranty Replacement Promise lets you ride with confidence. Join The Ride for fun, fitness, and community.PLEASE NOTE: ALL BIKES ON desertcart COME UN-TUNED. PROFESSIONAL ASSEMBLY REQUIRED TO VALIDATE WARRANTIES! - 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! ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B077735F9M | | Additional Features | Aluminum Frame | | Age Range Description | Adult | | Best Sellers Rank | #767,232 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #86 in Road Bikes | | Bicycle Drivetrain Type | Shimano Tourney | | Bicycle Gear Shifter Type | Trigger | | Bike Type | Adventure Bike, Road Bike | | Brake Style | Disc | | Brand Name | Tommaso | | Color | Black/Blue | | Customer Reviews | 4.1 out of 5 stars 53 Reviews | | Derailleur Configuration | Front and Rear | | Frame Material Type | Aluminum | | Gear Type | cassette | | Included Components | Pedals | | Intended Riding Terrain | Gravel, Unpaved Trails | | Manufacturer | Tommaso | | Model Name | Siena Sport | | Number Of Speeds | 21 | | Origin | Imported | | Power Source | human power | | Size | S (5'6"-5'8") | | Skill Level | Beginner | | Specific Uses For Product | Gravel, Road, Trail | | Style Name | Black and Blue | | Suspension Type | no-suspension | | UPC | 712804708241 | | Unit Count | 1 Count | | Warranty Type | Lifetime | | Wheel Material | Aluminum | | Wheel Size | 29 inches | ## Product Details - **Bike Type:** Road Bike, Adventure Bike - **Age Range (Description):** Adult - **Brand:** Tommaso - **Number of Speeds:** 21 - **Color:** Black/Blue - **Wheel Size:** 29 Inches - **Frame Material:** Aluminum - **Suspension Type:** Rigid - **Special Feature:** Aluminum Frame - **Included Components:** Pedals ## Images ![Siena Sport Performance Aluminum Gravel Bike, Shimano Tourney 21 Speeds Road Bicycle Men - Image 1](https://m.media-amazon.com/images/I/71TvvpNXykL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Tommaso Siena Sport Performance Aluminum Gravel Bike, Shimano Tourney 21 Speeds Road Bicycle Men - Ascher Ultra Bright USB Rechargeable Bike Light Set, Powerful Bicycle Front Headlight and Back Taillight, 4 Light Modes, Easy to Install for Men Women Kids Road Mountain Cycling Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/65962839-siena-sport-performance-aluminum-gravel-bike-shimano-tourney-21-speeds](https://www.desertcart.sn/products/65962839-siena-sport-performance-aluminum-gravel-bike-shimano-tourney-21-speeds) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-10-09*
