Smaller than expected but, depending on the accessories' fitting sizes, should accommodate 3 or 4 extras, if need be. Adjustments a bit fiddly but ought to be usable on most bars or stems. There can be a bit of movement in the Xbar unless it is tightened to its maximum. Not sure how much removal and re-installation can be expected as the metal fixing 'strap' is very pliable and seems to be weak. A bit pricey, I feel.
