I just cleaned out my foot pump head last night. It was filled with sealant. It was blowing bubbles and sounded like there was something inside, so I completely agree: check your pump! Topeak's original tire gauge is good. It has an end that you can screw onto a pump to override the pump's non-functional gauge or to compare the two to see if the pump's gauge is accurate.
An excellent array of questions! I try to keep my drivetrain clean by cleaning it *frequently* rather than doing anything extraordinary. The usual cause of untimely wear is negligence.
Running a sram AXS derailleur and shifter with Shimano chain, cassette, and Crankset works well and gives you the best of both. Wireless shifting is precise, clean, and easy but the tooth profile and chain design on Shimano HG+ gives far superior shifting not to mention better spacing between gears compared to Sram. As long as the chain, cassette, and chainring are all Shimano it will work with Sram AXS (just not T-Type).
I run a Shimano XT Drivetrain on my Fat Bike and SRAM AXS on my MTB . Love the Shimano shifting but it’s not way better than SRAM. Smoother but You are full of ^%$%# Far Superior my Ass 😂
Before now I've dropped my chains into a sandwich box with white spirits and left it for a few hours, it's cleaned up a treat. Also brush cleaning the cassette with white spirit does the job of degreasing it.
I was choosing between computer and smart watch a few weeks ago. I ended up buying a Garmin Epix 51mm. I use it as a normal watch and tracking other activities with it on my wrist. If I go for a ride I have 3d printed a stem mount and use a HRM, cadence and speed sensors. So far it has worked great, it gives me the info I need and I can analyze the results later. I usually ride on roads I know well, but I can see the advantage of having a larger screen for navigation. For extra security I have a lanyard from a flashlight and a metal clip mounted around the stem.
Good advice for cleaning a chain... but better still is to switch to imersive waxing... then it basically stays clean all the time as any dirt is flushed out when it goes in the wax pot. Best source of info on this is from Zero Friction Cycling.
Totally agree. It seems to be ignored in the MTB world. Granted, it may not be practical in a UK winter (wet and sloggy) but for dry and dusty with occasional puddles here in the US, It works a treat! (as our UK friends like to say) quiet, and un beatable protection! Anna and a PHD GCN presenter just had a chat about it. I was glad to finally see it acknowledged by someone other than those who stand to financially gain from it's use. th-cam.com/video/Q98HvysE4n0/w-d-xo.html
I used a small chainring to get a nice low ratio on my budget fatbike build, with the smaller cassette that came with it (22T front, 34T rear), for quite a while. When I switched to 32T on the front and 50T on the rear, giving me a very similar ratio, the drivetrain felt more engaged and the chain stopped slipping or dropping. For the low-speed crawling I needed to do on the fatbike, the difference in feel was huge!
The new Garmin is just awesome. The digital bell is perfect for canal towpaths & is by far their best navigational release. I love the watches but if you have an Apple Watch you can attach your heart rate via a third party app. Job done.
Thanks for answering ly question! Yeah that incident traumatized me LOL. I don't go to max pressure to seat my tires bead anymore. I just go to about 40 at the highest. I think the blowout caused a tiny rip in the middle of my Ardent Race tire because sealant leaks out in one location. I may have to get a new tire.
Is there a chance the tire was not seated correctly in the first place? Did you check around the tire to see if the little ridge on the side of the tire is the same distance all the way around the rim?
I use both my smartwatch and my Kiox 500 when I am out on my bike, but I am looking to get a better computer. The new Kiox 500 is a lot faster than the 300, and the new updates are great, but I just want a little bit more from a computer that focuses more on me and not just on the bike. So, I have installed the Purion 200, so now I am looking for a computer to use now but will not ever give up my smartwatch.
Cleaning bike chain. If you clean your chain on the bike, using a brush, I’d consider this just a pre-wash…. If you want to get a chain really clean you have to take it off. Now-a-days I take the chain off and give it a pre-wash in some kind of container with a lid and a solution of Simple Green so I can shake it about, let it sit a while. Then do a hot water rinse. Now I put it in the ultrasonic cleaner. After 20 minutes at 60c t hake it out and give it a hot water rinse. Dry the chain. I used a heat gun this last time. Now the chain will pass the white glove test. I used the clean white shirt I was wearing, the inside…just in case. I’ve actually got the same results with just Simple Green and a big plastic jar with some scrubbing / rinse and repeat. The ultrasonic method with a pre-wash is faster, you can do the whole job in a half hour.
#askGMBNTech where the rear shock is mounted what’s actually rotating? Is it the axle through the bushing or is it the bolt that’s holding it all in place?
@@neilelliston it is exactly the same, as shown is side by side comparisons. I think you think people are wearing their watches while riding. You are wrong. People mount their watch to their bikes the same as a bike computer.
I think the thing with cleaning a chain is it just won't work on its own. You have to clean the drivetrain. No matter how spotless your chain is, it'll gunk up in seconds if you have old oils and muck stuck to the chainring, jockey wheels and derailleur cage.
Many riders are using SRAM AXS D-Type with Shimano cassettes and chains. Shimano 12 cassettes run really well with that SRAM stuff, indexing is the same. I find the Shimano cassette also runs quieter than SRAM.
#AskGMBNTech About the question on mixing SRAM wireless with Shimano. Why not try Shimano DI2? I don't see much information about it, I know it isn't wireless and probably more for emtb?
#ASKGMBNTECH Converting to Tubeless, I have COMMENCAL Meta HT Race with Spank wheels which are 28mm inner diameter, I purchased Peaty’s Tubeless conversion kit with the 30mm tape based on internet search, however, I went to Spank TH-cam video on how to do the conversion correctly and they say you need 25mm tape for 28mm inner diameter rims. I live Central Southern Africa and it took nearly a month to get the Peatys one through Amazon delivered, have I got the right kit or not? Please help.
@@danielbanister8269 I wonder what the people who use gorilla tape do... 🤔 Do they trim a couple of mil off the edge or do they just leave the extra on there? 🤔
#askgmtbtech any cunning solutions for carrying tools and punture repair/tube on the bike? I don't want to wear a rucksack and there's not much space on my frame (Turbo Kenevo). I just shredded my seatpack as it touched the rear tyre after a jump and emptied the contents on the trail!! Need a clever alternative.
#ASKGMBNTECH My braking performance has recently been terrible. They keep squealing a lot, fading and have no power. I’ve tried everything from resurfacing them to bleeding them, nothing helps. They’re entry level Shimano Mt-201s. I’m thinking about changing the rotor to one that is compatible with metallic pads and get some aftermarket metallic pads to go with it. Will this fix the issue?
#askgmbntech i have a Marin bobcat trail. It came with a straight tubed fork as standard. Installed a hope bottom headset cup so I could get a modern tapered fork in there. Left the as top as was, with open cage bearings. Would love to know which size of top cup I'd need to get closed bearings in there. Tried 2 and both been wrong.

Since Silca came out with their system it's so fast and easy and am switching all of my bikes (mtn/road) over as I change out chains.
I love tech especially when it’s combined with MTB’s. In my rides I use Strava with my Apple Watch ⌚️

Regarding sag, do not rely solely on the manufacturer recommended pressures, actually measure sag.

What do you think of microshift advent x drivetrain?
Regarding on sag on forks, Fox recommends 15-20% and Rockshox recommends 20-30%. Should I measure sag while sitting or in a standing neutral position?
Standing would be better.
Yes @TivonSanders is right, measure your sag in all your riding gear in your neutral standing position! Use a wall or a mate to help you balance 👍

Super-hot water with Dawn dish soap in a bucket will get most chains clean.
