Reliable, affordable, workhorse Shimano 105 front hub
Its shipment arrived, I took the hub out of its Shimano packaging box, gave the hub a look-over, counted its 36 holes, noted it is an all-around good looking hub, then put it back in its box and that is what I know about it. By reputation the Shimano 105 series is said to be the slightly heavier but equally reliable and more affordable, go-to version of the Shimano Ultegra series of components.
