Is there a standard thickness of spokes ? 14 gauge ? Yes , almost all bike spokes are the same size , 14 ga which is is 2 mm . Some are butted and are narrower in the middle , but the ends are still the same size . If I buy 14 gauge spokes , will I need 14 gauge spoke nipples ? Or does the 14 gauge fit into the 15 gauge hole from the spoke nipple ? They should come with nipples . If not , ask the shop to include the correct ones . If I buy a replacement hub of a different brand , will any thickness of spoke be compatible ? As above , all spokes should be the same size so you shouldn ' t have any issues . If I can ' t find exactly 244 mm length spokes , how much shorter or longer would still be compatible ? You have to calculate spoke length depending on hub and rim choice . Choosebuy a new hub first , then buy spokes . Do I need to get the same type of metal of the spokes on the other side of the wheel ? I think the ' re a galvanized alloy , nonmagnetic . 99 % of spokes are stainless steel . I would advise against galvanised mild steel , they ' re crappy . Anyone know of any HyperglideC compatible 32 hole rear hubs ? You say 8 speed , but also HyperglideC . HyperdriveC is 11 speed , Hyperglide just refers to the shape of the teeth and doesn ' t affect fitment . 99 % of the time , 8 speed Shimano type cassettes will fit on all 8910 speed ShimanoSRAM type hubs , so you shouldn ' t have any issues there . You should also replace all the spokes , not just the drive side , especially as you ' re changing the hub too . I don ' t mean to be rude , but by the sounds of it you aren ' t ready to jump straight into wheelbuilding , sorry . It ' s a complicated process , and if you fuck up the results can be catastrophic . I ' d take it to a bike coop that can walk you through the process and watch out for any mistakes you might make . They will also have all the tools you need .
