Frank Jalbert, left, of Lewiston and Ryan Walker of Auburn mix cement Wednesday at Mount Apatite in Auburn. The volunteers with the Central Maine chapter of the New England Mountain Bike Association (CeMeNEMBA) are installing a trailhead workstation in the parking area on Small Road for cyclists to use when making minor adjustments to their bike. Jalbert, owner of Busytown Bikes in Lewiston, donated the Park Tool stand to CeMeNEMBA. He also donated the workstation that volunteers installed at Range Pond State Park in Poland. The repair station at Mount Apatite will be functional in time for the 1 p.m. Halloween Ride on Sunday. Participants are encouraged to wear a costume. Daryn Slover/Sun Journal
