    Shorten or extend controller cables - looking for connectors

    Chain tensioner with Shimano Nexus 3 and BBSHD

    Is there a chain tensioner that is recommended for my setup - Nexus 3 and BBSHD? I've used the eclypse MT95C but the build quality is poor, and it's too narrow for single speed chains or a seven speed with the KMC pin.

    Tire Size recommendation for commuting

    My commute is primarily bike paths, some roads and some pavement. As expected, there are some potholes, root damaged bike paths, and under 10% grade across the route. I ride 26x2.4 tires on my hard tail, with a lower PSI (35) to give me a little softer ride. The trade off is my cruising speed...
