M Part Summit Rear Pannier Bike Rack Alloy Black

M Part (by Madison) really should publish the dimensions, especially clearance dimensions, of their pannier racks (as Topeak do, for example), because without knowing those dimensions buying online is hit and miss… In our case, with Boardman SLR bikes with 700c wheels, we needed a wide fitting at the bottom, and many pannier racks were too narrow. The Summit, however, erred the other way and was at least 10mm too wide, with 165mm between the stays at the bottom. It was also the case that if fitted with the bolts they supplied, the bolt protruded on the cassette side into the smallest cog with risk of fouling the chain. So we had to add spacers, which helped avoid straining the bottom stays of the rack inwards too far. Also, on a bike for small riders, the upturned front of the rack at the top is so close to the saddle that it fouls any saddlebag, meaning the two cannot be used together. However, the rack is obviously of excellent quality, very sturdy and well made, and able to be adjusted to a range of frame sizes providing you have nearly 165mm width available at the bottom. It's perhaps too sturdy for an SLR road bike, though, so we will only attach the racks when we need to carry more than will fit in saddle and top tube bags.
