Rockrider ST100 27.5 Mountain Bike - $199 Sale Price
Published on 09/04/2026 at 08:43 | Editorial responsibility: Rafael Müller, Editor-in-Chief AD HOC NEWS
Rockrider Adult ST100 27.5 Mountain Bike pairs a CGF frame with 80 mm suspension and 27.5-inch wheels, with 26-inch wheels in XS. The US Decathlon listing shows a sale price of $199.00 and a regular price of $399.00 as of 09/04/2026.
Frame And Rolling Setup
The US product page lists a raised-position CGF frame, an Ergofit hammock saddle, and a Flex stem. It also gives wheel size as 27.5 inches, with 26-inch wheels in XS.
The same page says the bike uses 80 mm suspension and comes in Black. Those details match the adult ST100 listing on Decathlon's US site.
Price And Positioning
Decathlon's US price tag puts the ST100 at $199.00, down from $399.00 on the same page. That places it in entry-level hardtail territory for riders who want front suspension and a simple 27.5-inch setup.
Compared with the ST100 support page in Germany, the same family is described with a 100% aluminum CGF frame, 80 mm suspension, V-Brake brakes, and 21 gears. The US listing keeps the same core layout while presenting the bike in a black finish and adult sizing.
What Stands Out
The ST100's setup is built around first rides on mixed ground, with a hardtail frame and front suspension instead of rear travel. The listed wheel sizes and suspension travel give it a clear mountain-bike profile without adding extra complexity.
For riders who want a basic mountain bike with published sizing and a straightforward parts list, the ST100 keeps the focus on frame, fork, and wheels. The price difference between $399.00 and $199.00 is the sharpest number on the page.
Bottom Line For Buyers
Rockrider Adult ST100 27.5 Mountain Bike is a simple hardtail with 80 mm suspension, 27.5-inch wheels, and a $199.00 sale price. It fits riders who want a basic mountain bike layout and published adult sizing details.
