This item was stored in a toolbox. I didn't use it much, but would it be suitable for maintaining road bikes and cross bikes? There was some light rust, so I applied a rust removal and conversion agent, followed by a rust-preventative coating, and then applied oil to prevent further rust. This is a set of steel hex wrenches, sizes 1.5mm, 2.0mm, 3mm, 4mm, 5mm, 5.5mm, and 6mm, an 8-piece set. Shipping will be via anonymous Yu-Packet. Thank you for your interest. - Set Contents: Hex wrench set - Color: Orange (holder) - Material: Steel (wrenches) - Holder Shape: Triangle Thank you for looking.
