    Fork for new 29r build

    So I'm new to bike building and I'm going to put together a 29r ( with my friends help ). Wanted to ask something here first. How do I determine if the Marzocchi fork I'm looking at will fit my frame? This might be a dumb question, but I thought I'd ask before I go spending the $$ !! Do all 29r forks fit all 29r frames ??

    Axle to crown wise all 29er forks will fit 29er frames. You need to match the forks steerer tube with your head tube. Is your head tube 1 1/8th. 1.5, or tapered.....1.5 at bottom 1 1/8th at top?

    Frame has a FSA Orbit C-40 Headset. Looked it up and it says it's 1-1/8 x 1.5 tapered. No idea what this means...lol, but I'm a quick learner. Help !

    Fork for new 29r build

    I'm a noob too, so would wait on someone else who is more experienced, but I believe that will work with your frame

    Yes -- you have a tapered headtube.

    Make sure your front hub will work with the QR15 thru-axle on the fork.

    The fork you mentioned has a QR15 axle

    As opposed to the standard quick-release, like this...

    You'll need to make sure your hub has the ability to accept a QR15 axle, if you want to run that fork.

    is the fork that you are looking at new or used? If it is used then you need to measure the steerer tube length. Installed forks usually have the steerer tube cut down to fit, so if this is used then you need to measure the length v. The combined height of the head tube, headset cups, stem and at least one small spacer.

    You may want to ride it a bit at full steerer tube length before having it cut down, just to see what height is the best fit for you. You do this by placing spacers both below and above the stem. Or if the height doesn't matter then just have it cut down and leave yourself some room for spacers. the height and amount of spacers are preference but you need at least one spacer. But once you cut the tube that's it--if you have cut it too short...

    Thanks cjsb. I really appreciate the help. I'm 6'-2" . I don't think I'll cut it unless it's really high.I think it would be much easier to sell if I want something different. I like my position slightly higher. My 26r has 3 spacers on the bottom an 2 on top. It works well at this height and leaves me the option of raising it further if its needed.

    They're a bit on the heavy side and wanted some opinions. Perhaps there's better options, at a higher cost I'm sure.

    Decided to X this wheelset and go for the real deal. Got some Mavic SLRs. Got a nice carbon frame with a nice fork to boot. Why cheap out on the wheels !!
