    After being out of mountain biking for about 10 years and the bike I was riding at that point was about 10 years old, I discovered all of the newfangled technology and proprietary equipment when I decided to get back in. Deciding which BB & crank and either Shimano vs SRAM was info overload since I wanted to build up a bare frame. Luckily, everyone I spoke to, including you guys, was quite helpful thru all of my phone call.

    OK,you suggested we ask. The info from the bicycle sellers states. "Bottom bracket VP-BC73 sealed bearing square taper." When searching online, there are plethora choices. Just as you stated! It is also suggested that a tool purchase is necessary. I don't have a problem with that.
    It's not a rocket launch! The info provided is complete per the sellers website. If you can help, that would be truly appreciated. No matter,thanks for the advice. Enjoy your day.

    Great video! It helped, thanks:) Now I know that likely the threaded 83mm Saint BB for my 06 Stumpjumper S-Works is likely compatible with other Shimano Hollowtech Cranks (1×;2×;3×), that the Saint is not limited to the 1x Saint Crank, but that the Saint 83mm BB is a heavy duty, down hill oriented system to work in the Stumpjumper, where the name suggests heavier duty. The smaller BBs can be for the Twig Rovers

  • @johnpossum556
    @johnpossum556 4 года назад

    My radcity Ebike uses an 83mm "downhill" sized BB though it's clearly a street bike. I like that they oversized parts. It really helps because the bike is more like a moped and less like a bike. The frame is a tank.

    Cleared up a lot of confusion and questions. Next in this series could be head sets. Also, I'm curious as to whether upgrading to a high end bottom bracket (Chris King, etc.), is really worth the money, keeping in mind proper timely maintenance will be performed.?.?.?.

  • @marinesailorsolder27
    @marinesailorsolder27 4 года назад

    I was hoping to be able to get a new bottom bracket before pulling the one that's in my frame, but I guess that's not possible. I have a Triace A310 Stormount frame and I know the bottom bracket is square taper, this is a new frame, but the spindle doesn't want to turn easily, so I figure there's a problem with the bottom bracket, I would also get a new spindle and since I have Shimano cranks the brand is easy, but I'm not sure on the size, so I guess I'll be pulling the bottom bracket. Thanks for the guidance that the video gives, it was enlightening.

      Running out of ideas? Nah just kidding 😉 But I'm not sure if this is possible for you to do, but I would really like you comparing Mid end and High end Forks and shocks. Not for racing but for regular mountain bikers like most of us viewers and can one really tell a big difference. For example A RockShox Relevation and a Pike RCT 3 or 🦊 Rhythm 34 and a Factory 34 and everything in the middle.

    • @th_js
      @th_js 6 лет назад

      And also would like to see how to service a Fox fork and when to actually do that, I know there are recommendations but it really depends on the conditions of your riding and how much you ride how hard etc... I have had my Fox 32 Performance Elite fork for 1 year and 3 months now and I have never serviced it, but there isn't appeared any major problems. Do I still really need to service it?

    • @th_js

    Funny thing. I bought a new Enduro, and in the first ride I bent the crank from a pedal strike. I asked the shop I bought the bike from what is my bb standard so I can order a new crank. His reply was "I am not gonna give you the recipe to my secret sauce." I was a bit disappointed with the answer but at least I got RUclips to save the day.

    • @topspot4834
      @topspot4834 4 года назад

      I would've done a drive by and shot the place up. That's when you call the manufacturer and report that shop (and get the info) ... Also every shop should not only help with that, but give you a manual with all that info in there.
      Seriously, I'd flip my lid, but I know my LBS would never do that Busch league stuff.

    Many thanks for the video. I have a problem with damaged threads in the frame. The tool needed to recut them is far too expensive. Research shows that you can get, so called, threadless BB's. There are several on ebay that might do the job, but its the dimensions that are confusing me. These are marked on the body of the BB but I don't know what they refer to. For example, there in one marked ' L68x116mmR '. I guess the L and R refer to left and right sides but what do the two measurements refer to? Thank you.

I have a set of raceface chester cranks 11 speed, 32t 170mm 104/64. one of the cranks broke and i need to replace both of course. But i can still use the chain ring and bottom bracket. Im looking for a pair of cranks that could be adaptable, and cheap. If the bottom bracket width of the frame is 92mm (and i cannot measure anything inner because i dont have tools myself), which is the size of the shell normally? i have a yeti sb6.

  • @totojejedinecnynick
    @totojejedinecnynick 6 лет назад +1

    Threaded or not buying that frame/bike. PF is a costcutting measure (look up how those large internal threads are made into frame/BB and why it is nigh impossible to do so with carbon frames) - but it will cost you more in servicing. You really need just one stupidly simple steel wrench to service threaded BB of any kind, size and brand. 8 Euro wrench, on which you can hammer to loosen the damn thing. (and if you buy odd/smaller BB like ever so popular cheapish Shimano XT, it comes with adapter for that wrench anyway).
