    Need help with parts

    I am trying to figure out what the best approach is to this problem. I recently broke off the release lever on the front wheel. So, I now have to replace it or replace the wheel(s). Here is what I know about the bike. It is a 2009 Specialized full suspension Stumpjumper with DT Swiss X420SL wheels. I have 9 gears and disc brakes. I have had to replace the front fork with a Fox 32 suspension. Here is what I need help with:

    1) I found out that the through bolt is 9mm. I was able to find a 9x100 front through bolt but when I took a tape measure to the length of the broken bolt it was more like 13xmm long. Am I measuring the correct bolt length or will the 9x100mm bolt fit that wheel

    2) if it will not fit the wheel, then what wheels should I replace the current DT Swiss X420SLs with?

    Finally, please do not reply with "You should get a new bike". That is not an option at this time. It might be once my employment situation is more stable post COVID, but right now I don't really have the $ to spend on a new bike. I want to fix this one in as cost effective a way as possible.

    Are you sure it is 9mm and not 15mm

    I have the broken bolt and measured the diameter. It is 9mm. I am assuming that they are speced with the diameter.

    The bolt will measure longer than what the specs say, The 100mm is width of the hub between the fork drop outs. the 9x100 should work

    Great. Thank you. Figuring out what the right parts are is so hard with bikes. There are way too many options and don't even get me started on metric v English units.
