Build a bike that fits, performs, and grows with you. A complete guide for beginners.
Starting your road cycling journey is exciting, but the most important decision you'll make isn't which complete bike to buy – it's which frame to build upon. A quality frame is the heart of any bike, determining comfort, performance, and future upgrade potential. This guide walks you through the 10 most critical factors to consider when choosing your first road bike frame, whether you're buying new or planning a custom build.
1. Frame Material: Carbon vs. Aluminum
For beginners, aluminum frames are affordable and durable. But if your budget allows, a carbon fiber frame offers lighter weight, better vibration damping, and a more comfortable ride. Premium options like the Mondince FM126 carbon frame weigh as little as 760g and provide race‑ready stiffness without breaking the bank.

2. Frame Geometry: Endurance vs. Race
Endurance geometry keeps you more upright, reducing back strain on long rides – ideal for beginners. Race geometry is lower and more aggressive, better for speed. Look for frames labeled "endurance" or "sportive" for your first bike. Our bike sizing & geometry guide explains reach, stack, and how to choose the right fit.
3. Tire Clearance
Wider tires (28mm–32mm) offer more comfort and grip on rough roads. Many modern road frames now clear 30mm or 32mm tires without sacrificing speed. This future‑proofs your bike for light gravel or bad pavement. The FM086 and FM126 both clear 32mm tires. For dedicated gravel riding, explore our gravel-specific frames with up to 50mm clearance.
4. Bottom Bracket Standard
Threaded bottom brackets (like BSA or T47) are easier to maintain and less prone to creaking than press‑fit. The T47 standard used on frames like the Mondince FM126 combines the best of both worlds – wide bearing stance and threaded simplicity. For more on BB standards, read our components guide.
5. Brake Type: Rim vs. Disc
Disc brakes (especially hydraulic) offer better stopping power and work well in wet conditions. Most new road frames come with flat‑mount disc brake compatibility. If you ride in dry areas only, rim brakes are lighter and simpler. All Mondince road frames are disc‑brake ready.
6. Axle Standard: Quick Release vs. Thru‑Axle
Thru‑axles (12x100mm front, 12x142mm rear) provide stiffer wheel attachment and better disc brake alignment. Almost all modern disc brake frames use thru‑axles – make sure your frame supports this standard for future compatibility.
7. Seatpost Size and Type
A standard round 27.2mm seatpost offers the widest choice of aftermarket posts, including suspension seatposts for added comfort. Some aero frames use proprietary shapes – avoid those if you like to customize. The FM086 uses a 27.2mm round seatpost for extra compliance.
8. Derailleur Hanger Standard
Look for frames with a UDH (Universal Derailleur Hanger). This SRAM‑led standard is becoming universal, ensuring you can easily replace or upgrade your hanger in the future. All Mondince road frames feature UDH.
9. Internal Cable Routing
Internal routing keeps your bike looking clean and protects cables from dirt. However, fully internal routing through the headset can make maintenance tricky. For a first build, semi‑internal routing (cables enter the downtube) is a good balance. Mondince frames use fully internal routing through the headset for a sleek look.
10. Budget and Upgrade Path
Your frame is the long‑term investment. Spend more on a quality carbon frame now, then add affordable components (wheels, groupset) later. A frameset like the Mondince FM126 lets you start with a pro‑level chassis and upgrade over years – much smarter than buying a complete bike with compromises everywhere.

Frequently Asked Questions
Should I buy a complete bike or build from a frame?
Building from a frame lets you choose every component and often saves money in the long run, especially if you plan to upgrade. It also gives you a deeper understanding of your bike.
What size frame should I get as a beginner?
Use our sizing guide and always prioritise stand‑over clearance. If between sizes, size up for comfort.
