    As a full-time mechanic, I'm often surprised at how much of fixing and tuning bikes is taken care of by cleaning and getting lube where it's needed.

    One thing I learned is to use the SAC-2 grip compound sparingly. I had a dropper seat post that slipped in my aluminum frame even after I tightened the clamp to the point that I thought it would crush the post itself, so I took some SAC-2, applied a generous amount to the post, and slid it in place. It only went about halfway in before I couldn't budge it, and it very nearly got stuck. Thankfully, I was able to pull it out with a fair amount of effort, wiped off most of the compound, and tried again. It worked much better the second time.

    Chek and pay attention to tire pressures think is great info. Especially now tubed, tubeless, hookless, different different sidewalls, and much more changes pressures needed. Go to road wheels which have lower volume being more narrow those pressures can change drastically.

    Something more specific I see all the time in my shop is people that over-tightened their seat clamp bolts on dropper posts. It's a great way to make your $300 dropper not move. I use friction paste instead of grease on dropper posts so I don't have to torque the bolt down so tight

    • @Ferrari255GTO
      @Ferrari255GTO Місяць тому

      I don't get why people do that, the one time i even tried tightening a seat clamp hard ( i had gone back to a regular post as my dropper had a non-fixable failure ) the bolt wanted to self-destruct before i even got half way to too tight. And it was not a crappy clamp either, that MF was 20 bucks from KCNC ( wich seems ridiculous for what it is but they had nothing else in the shop when i bought it, i know, there's probably way more expensive ones around, but still ). I never needed friction paste on my dropper, just torqued the clamp as intended wich got me ready to go.

    IF you use a pressure washer don't use one of those cheap electric ones that have just a pencil thin stream, you need a stronger one with a fan pattern so you have a strong, but very thin fan sort of stream. I can get dirt off of flat surfaces easy but doesn't drill down into bearing seals as bad. Also be smart about where you apply the stream at what angle and how close you are too it.

    When i see comments of people complaining about emtbs that are on their 4th motor i can't help but suspect that a pressure washer was at least partially involved in such a saga. Yes there are sometimes manufacturing defects, but for it to happen more than twice it seems likely to be more than bad luck and some user error may be taking place. Be careful with pressure washers at trail centres... they are often far too powerful for the task of washing any bikes and will force water into bearings and electronics. Last time i used one i had to keep it 2 meters away from the bike to feel that i wasn't applying excessive water pressure.

    Great insights from the ParkTools legends. Hands up I made a mistake with a torque wrench… TW 6.2. and I damaged it. It’s great that ParkTool can warranty or repair it. What’s not so great is the UK importer cannot do this and I have to send the (heavy) wrench to the U.S. The kicker is that the cost to do this, including the repair, is the same price as the wrench! Not great. Can ParkTool provide certification for the UK importer to service their equipment?
    The current situation isn’t environmentally friendly as a choice between shipping a wrench 6000 air miles or send it to landfill and buy a new one?

    Don't put too much trust in torque wrenches. Most of the bolts i've broken in my life were from trusting the torque wrench either having it set wrong, the torque spec being incorrect in the manual, or my latest blunder, not realizing my wrench didn't measure in reverse on a left-hand thread. If it feels wrong stop and reassess, go back to the manual double check the wrench, look up a youtube video etc.

      It's also for brand new threads and a freshly calibrated torque wrench, unfortunately there are too many variables to consider to write down a torque for all of them. If you use a torque wrench, thread lock/grease (depending what's needed) and set it to the correct torque 99.9% of the time you'll be fine! 👍

    You know this is common sense should be common sense. Your pressure washer should be set up to do 1000 psi and 2 gallons of water. The problem here is that people are using very cheap poorly executed pressure washing systems. No one in the bike industry has come up with 1000 psi 2 gallons of water, per minute safe pressure washer with proper wash methods. People are all over the placewith trying to clean their bikes. It’s absolutely horrible.
