Hey guys.. new to the forum.

So i am making a new budget build for the season and i'm having some wtb frequency i19's laced on shimano slx m7000 hubs. I wanted to try it out myself but couldnt get far at it. I bought spokes and all but when i got to the lacing process i ran into some issues.

First thing that seemed odd was that when i got to the part where you start to cross the spokes my hub wasnt "locked" in position - it could be turned freely left and right.. that was not the case with the hub that was being laced on the tutorial i was watching. And second, when i tried to cross a spoke.. it was simply too short to make it to 3 cross i.e it barely made it into the rim hole, which is funny 'cause when i couldnt get the hub locked up i thought to myself that the spokes are too long.. so now i have no idea what is going on. Lenght wise i got these numbers from prowheelbuilder


I used dt swiss calc aswell and it gave me the same numbers. I measured the rim's ERD myself and i got the same numbers. Hub wise, it was the same eventho it's the older slx model in prowheelbuilder's database. What i noticed is that the flange diameter on shimano's tech docs is 53/54 mm but that is not hole center to hole center but rather a .. well flange diameter.. is this what is causing the problem or is it something in the lacing? My main concern right now is that i have bought the wrong spoke leght.

if you are using the length provided by the pro wheel builder you should be good.... sounds like a lay up and crossing issue... find a good wheel building video and take your time

Any chance youd be able to upload a photo? Im curious because, even though your hub dimensions are wrong (i have access to all the numbers of various hubs) they arent far off enough to make you experience whats happening.

I know this is very simple but you're sure you put the spokes in the correct side?
