Like the SciCon Travel Plus Racing, the Travel Plus Triathlon bag was made for the triathletes who need to protect their bikes from scratches and abrasion while moving in and out of vehicles, hotel rooms, and the like. It's made of a durable nylon outer material with foam padding throughout to keep your machine safe. Designated wheel pockets keep your hoops separate from the frame, and four handle loops and a shoulder strap let you move the bag around with ease. The base is double reinforced, and there's a burly zipper along the top. The bag is compatible with most road, tri, and mountain bikes. Please reference the specs for exact measurements.
