Solid quality kids hardtail MTB. 70mm travel, 9 speed 11-34, Sram X7 derailleur, SRAM NX cranks with 30T x-Sync chainring, Tektro Hydraulic disc brakes. Full spec is here: https://tech.commencal.com/bike/COMMENC ... 7/172.html.
Bike is in good shape and has had a moderate level of use: family rides, a couple of mountain bike camps, commuting to school from time to time and a couple of cross races. Shocks were just serviced
If your kid is roughly between 120 and 140 cm height this bike should fit fine
This bike is exactly as spec other than the tires were upgraded from the stock Kenda Small Block 8 to a much beefier VeeTire Crown Gem 24x2.25. Weight is a bit above the manufacturers claimed weight (likely because of the beefier tires and because bike companies like to report weight sans pedals. As is I weighed it as 26.25 pounds (not exactly featherweight but lighter than some of the 24" offerings from the big manufacturers)
