I’ve become a big fan of dynamo hubs. For commuting it’s great to have bright lights without charging batteries. For touring I feel the same and rely on dynamo power to charge the gizmos I can’t live without. Apart from the weight penalty, hub dynamos are pretty terrific.

Check out this upgrade for a rider’s Surly Long Haul Trucker. This wheelset re-uses the stock Shimano XT rear hub and adds a new XT dynamo front. Since this LHT is ridden unloaded too, I’m mindful of weight and mitigated the dynamo’s added mass with lighter Mavic rims and butted spokes. Surly uses straight gauge spokes on their stock wheels, which targets price rather than function — butted spokes are a must for touring in my book.
