More Shimano? - Which Shimano groupset should you choose for your bike? A review from an expert at a bike shop in Mokotów.
🔹 Claris R2000 – budget road bike, easy commute
Claris is an 8-speed set-up with 2x or 3x options. Simple levers, rim or mechanical disc brakes. It's a clamp-free mount for fitness bikes, recreational bikes, or everyday urban "pavement riding." It works, is durable, and is inexpensive. The perfect choice if, for once, you don't want to overpay.

🔹 Sora R3000 – fitness and solid recreation
It's only 9 speeds, but the Sora has better cable routing, the option of hydraulic discs, and an extended cassette range. It performs significantly better than the Claris over longer distances and with more demanding rides. It's a great base for a "drop bar" bike for city riding or weekend getaways.

🔹 Tiagra 4700 – commuting and fitness at the next level
Tiagra is a full-featured 10-speed drivetrain with slim levers, ergonomic controls, and the option of hydraulic brakes. Its long cassette range and well-balanced durability make it ideal for those who ride daily but don't yet want to go 105. It's often found on touring or city bikes with longer-distance gearing.

🔹 105 R7100/R7150 – sweet spot for several disciplines
The 105 is a 12-speed drivetrain—available in both mechanical and Di2 (R7150) versions. It's been hailed as the perfect blend of quality, smooth operation, ergonomics, and reasonable price. Ultegra on the road, but 105 on the wallet. An excellent choice for someone who rides a lot, trains recreationally, or wants a gravel bike with sensible components.

🔹 GRX (400/600/810/827) – Gravel and bikepacking
The GRX was built with gravel in mind: a clutch in the XT derailleur, flares in the levers, compatibility with 1x/2x and a wide range of cassettes. The GRX 400 is Tiagra-level, the GRX 600 and 810 are the 105/Ultegra equivalents in quality and price. New: from 2025, the GRX 1x Di2 (RX 827) with "Shadow ES" and a fall recovery mode is available—fast, precise, and reliable even off the pavement.

MTB and gravel groups other than GRX
🔸 XTR / Deore XT – top-of-the-line MTB
The wireless XTR Di2 (M9200/M9250) offers complete professionalism—up to 12 speeds, beautifully ergonomic levers, smooth shifting, and superior durability. The XT is closer to budget bikes, but still durable and precise. Perfect for bikepacking and classic off-road riding.

🔸 SLX and Deore – golden mean and standard off-road
The SLX offers a lightweight 12-speed, Shadow clutch, but fewer plastics than the XT—the perfect balance between durability and cost. Deore is the standard for budget and touring bikes—now in 12-speed and often used on budget gravel bikes.

🔸 CUES – new system replacing Tiagra/Sora/Claris
Coming in 2025, the CUES drop-bar system combines hydraulic discs, 1x and 2x options, 8-11 speeds, and elegant Tonic ergonomics for gravel/functional city/terrain bikes. It's designed to replace the Tiagra, Sora, and Claris as the new standard in reliability and versatility. Perfect for those looking for versatility without compromising on budget.
