Boasting top-of-the-line race technology, the RC503 is a high-performance road cycling shoe without the high price tag. The breathable, lightweight upper provides all-around comfort and a superior fit, while the carbon-reinforced midsole delivers the kind of stiffness and stability you’d expect from a high-end cycling shoe.
FEATURES:
- Stable and Powerful: Borrowing its design and technology from pro-level racing shoes, the RC503 utilizes power-zone lacing over the toe box and a carbon-reinforced nylon midsole for impressive stiffness, rigidity, and foot hold. The lower stack height helps to create a more stable pedaling platform, reducing foot movement and increasing power transfer from rider to road.
- Ultimate Comfort: Constructed using a seamless pattern of performance materials, the laminated mesh upper securely wraps your foot and reduces unwanted gaps or pressure points. Supple synthetic leather and lightweight TPU mesh keep you ventilated and cool, while the BOA L6C dial allows you to make adjustments quickly and easily even while riding.
- Best-in-Class Fit: Full surround laminated mesh upper is supple, durable, and integrates seamlessly with midsole for a snug and secure fit
- Lightweight and Stiff: Low stack height carbon reinforced midsole with stiffness level of 8 stabilizes your foot and transfers more power to your pedals
- Unrivaled Comfort: Synthetic leather and breathable TPU mesh upper keep you comfortable and dry on long rides, while BOA L6C dial closure promotes a perfectly personalized fit
- Multiple Options: Color choices include Black, White, and Cyber Blue, while sizes run standard 38-48 plus wide 40-48
- Compatible with SPD-SL Cleats: Easily clip into SPD-SL pedals for optimal pedaling efficiency

Very easy to use
Size: 12 Pairs / 24 pcs
I have an Onkyo audio/video receiver along with an Emotiva amplifier. Both have speaker "post" terminals which will accept banana plugs, OR I can connect the speaker wires by unscrewing the posts, poke the speaker wires into the terminals and then tighten the posts. The problem with poking the wires into the terminals and tightening the posts vs using banana plugs is that there is a risk of the wires touching the metal on the back of the chassis or touching other speaker wires, causing a short if one is not careful. With banana plugs, they simply plug into the back/top of the posts, eliminating the rsick of a short circuit. They can also be unplugged very easily if needed. Banana plugs are DEFINITELY the preferred way to connect speakers to an receiver or amplifier if they have post-style terminals.
These particular banana plugs came in a package of 12 I believe. They were very reasonably priced, and simple to connect to the end of the speaker wires. Simply unscrew the banana plugs, use a small, standard jewelry screwdriver and loosen both of the set screws, insert the speaker wire, then tighten the set screws, and then screw the banana plug back together.
The plugs have either a red band which would typically be used for your "Right" speakers, or a black band which would typically be used for the "left" speakers. The banana plugs insert into the top or front of the speaker terminal posts on the amp and receiver. They fit VERY snug, and so I did have to apply just a little bit of pressure in order to insert them into the posts, but once plugged in, rest assured they're not going anywhere. They are snug.
I highly recommend these.

Heavy-Duty 4 AWG Cable With Flexible Insulation
Size: 10ft, Color: 4awg
I am satisfied with this 4 AWG cable. The insulation coating is soft, and the cable itself is very pliable, making it easy to bend and route into the configuration needed for installation. Despite the flexibility, it still feels like a heavy-duty cable designed to handle demanding applications.
I am using this cable to provide the necessary amperage to start the generator on my trailer, and it performs as expected. I also like that the wire gauge and cable properties are clearly printed along the side of the insulation, making identification easy during installation or future maintenance.
The cable arrived in good condition with no obvious odor from the insulation or packaging. Overall, this appears to be a quality heavy-duty cable that is flexible, easy to work with, and suitable for high-current applications.

True copper battery cables that are high quality
Size: 10ft, Color: 4awg
I love having heavy duty cable on hand for my cars. It's so nice to be able to make your own starter and alternator cables when restoring cars.
These cables are 100% copper, not CCA (copper clad aluminum) like many others are. Copper is far superior for conductivity and handling higher loads.
The rubber on the cable is thick and yet very flexible..it's clearly marked and seems very durable. I like to use a hydraulic crimping tool and then add marine grade heat shrink tubing with the adhesive inside of it to keep it as weatherproof as possible.
