Is the Vaast R/1 good for beginners?

Not really. Its race geometry and stiff frame reward flexible, experienced riders. Beginners are better served by an endurance bike with wider tires.

What groupset does the R/1 105 use?

The model name points to Shimano 105, and the bike ships with hydraulic disc brakes. Confirm the exact groupset and gearing with the seller before buying.

Can I fit wider tires?

It comes with 25mm Vittoria Zaffiro Pro tires. Clearance is not stated, so check with the seller before fitting anything wider.

Does it come with fenders?

No. The frame and fork are fender-ready, but fenders are sold separately.

How does magnesium compare with carbon?

Magnesium is stiff and light for a metal frame and costs less than carbon, but carbon is lighter still and more common, so service and resale are easier.

What size frame do I need?

Sizing depends on the frame's geometry chart, which is not given here. Compare stack and reach with a bike you already ride, or ask the seller.

About the Vaast Bikes R/1 700c 105 Road Bike

The Vaast R/1 is a 700c road bike built around an AE81 SuperMag magnesium alloy frame with a full-carbon fork and Shimano 105-level hydraulic disc brakes. It is aimed at racers and strong endurance riders, with internal cable routing, 25mm Vittoria Zaffiro Pro tires and fender mounts. The frame is listed at 1250 g, which is light for alloy and competitive with entry carbon. It is a niche pick: magnesium rides and looks different from aluminum or carbon, and buyers should weigh that against more common frames.
