GT Bikes Female axle bolts are made for riders who know that loose axles are no fun. Two bolts, two washers – that's all you need.
Up front you get 10 mm x 24 TPI, in the rear 3/8 x 25 TPI. Standard sizes that fit most female hubs. The threads are clean, nothing frays, everything engages – just as it should.
They almost disappear in the setup, but you'll notice when they're missing. So: put them on, put them on, and get out on the bike. Solid basics you can rely on – like everything GT has been building for years.
