Need some new reading material? DirtRag issue 155 just showed up and it features tips for avoiding ticks, pumping pump tracks, and the hottest mountain bikes from the North American Handmade Show.


Here’s two new hubs for you to check out. First is the Schmidt Dynamo front hub or SON (Schmidt’s Original Nabendynamo) has significantly less drag than either tire driven dynamos or any other hub dynamo. Made by Wilfried Schmidt Maschinenbau in Tübingen, Germany, the hub is quiet and reliable, and is designed to give at least 50,000 kilometers of trouble free riding between servicings.  The hub powers several different six volt headlights including Schmidt’s own E6 halogen models, the Schmidt Edelux LED headlamp, both halogen and LED headlamps (as well as taillights) made by Busch & Müller in Meinerzhagen, Germany, Supernova lights from Germany, Spanninga lights from France, and Inolight LED headlights from Inoled in Ochsenhausen, Germany.

We also just laced up some CycleOps powertap hubs.  They give you access to real-time performance measurements and is extremely accurate.
