SIERRA DS LADY
Polygon
Crosscountry
SIERRA DS LADY is an alloy cross-country mountain bike (2024), by Polygon, from the Sierra Ds lineup. This model is best for riders who prioritize comfort and confidence on longer off-road rides, with a setup that gives you a comfort-leaning position, with a surface profile that is best for smoother trails and efficient rolling. Based on the metrics, key strengths are strong climbing friendliness for sustained uphill riding, strong value-for-money versus many similar bikes, and good fit flexibility for dialing in rider position. That said, what it gives up slightly is a firmer ride feel than comfort-first options. If this looks close to what you want, compare this bike on MatchBikes.com against similar models.
