Can it be used with the clamp on the seat post or down tube? Looking to pick up one of these myself tonight, if my local store has any in stock.
You should never clamp your bike via the downtube. Folk do it and mostly get away with it, but the bike frame tubes are so thin that they're not designed for the level of squeezing done by the clamps.
