That "fake" SRAM AXS is not an actual fake product. it's an EDS OX from WheelTop, the seller was trying to pass them off as SRAM.

I have a Cell Cycling x-shifter wireless rearmech actuator and shifter on my gravel bike (originally it was on my bamboo gravel bike) for a number of years. Different to axs as it uses a cable to pull on any rear mech, and can be used across any number of speeds for 2-12.
It's been so good I've just bought the newest version called NXS.

When I first started riding again I was extremely heavy and my hardtail had the standard 160 rear/180 front, and it was definitely not enough. However I never considered going bigger on the rotors. Instead I upgraded my front two pot caliper for a four pot one, keeping the same size rotors. It probably saved my life. 😆
Now that I'm lighter and still losing weight, I can feel the huge difference in breaking power from front to rear, and I'm considering increasing to a 180 rotor in rear. I think that should get it feeling smooth.
Thanks for another great show, Doddy! 👍

I do the dry tubeless way. I've always struggled to get the tire to seat.

[ltrtg]

When I fitted the Vittoria Air-Liner MTB in my rear tyre. Before I fitted the second side on the tyre. I put my tubeless sealant injector through the valve and one of the holes in the insert. So the sealant would go straight in to the tyre and not have to make it's own way to the tyre.

#AskGMBNTech - how about an episode looking at the tech of trail building and maintenance? From the back yard shovel approach (like Matt Jones) to the huge digger approach (like Sam Reynolds)...there is tech there to explore!

[calumenous]

223 in the rear and 203 in the front. That's on my mullet. Back tyre 2.6" Front 2.4". This is full moto style. Looks sick! There is some graphed out geek threads out there where the temps and stopping power has been measured. Bigger rotor on the rear is actually for heat dissipation which leads to sustained stopping power.

Is that the ESD system that you have shown? Because there is actually an app for ir. It can be found in your browser.

#AskGMBNTech Hi, been following you since early 2000's in the magazines! Thanks for the great content. I recently got Rimpact Pro tyre inserts front and rear and came off a 10 ft drop probably going a bit too fast. I'd just got them and was running pressure a bit lower than my average setup due to the thinking the tyre inserts would keep the tyres on the rim. Anyway, had a heavy landing on the front end and bottomed my fox 38's and the tyre exploded off the rim sending me over the bars and eating dirt! I was fine due to d30 protection but just wondered what your thoughts are on tyre pressures with inserts. Should I run them at my normal higher pressure? Thanks

[Saavvvv]

Appreciate the words on spray lubes. Had this conversation with so many people that think WD40 is a lube. 🙌

[DaffraontheMTB]

Do you have any experience with the new Continental tyres. The Kryptotal and argotal? Or maybe planning to test them? Would love to see your input on them. Thx

[Metal-Possum]

For road/gravel, forget Microshift as the "other" brand, and go straight to Sensah. They manufactured for SRAM before SRAM betrayed them and took their business elsewhere. Their current products are very affordable priced. Road shifters for about 40-50 quid a pair, no matter how many gears you want. They're ergonomic, easy to use, and have a very respectable build quality about them. They also produce some mountain bike stuff too which I have no experience with, but it also seems very reasonable.

For people who think its unfair that these "no name" products exist, just think how much dominance Shimano and SRAM currently have, every single new bike is sold with one or the other and some of these alternative brands are contributing some neat ideas on occasion too.

[DenisLeskovar]

Sensah makes quite good stuff. Going to do gravel build with Srx soon

[englishmtbinfrance]

I always run either same size discs or bigger on the rear. Done this for years now. Just suits me better for the way I ride.

[Metal-Possum]

For larger wheel sizes, I can't remember which website it was, but they were advertising mountain bike tyres as 30.5". The etrto for the rims was 642mm, which is identical to the old 28 x 1 3/8" or "700a" racing wheels we used sometime in the former half of last century. Reproductions of those rims are still being made if you know where to look, but some additional searching and it seems complete bikes with this wheel size exist for the Chinese domestic market. Tyres marked 57-642.

Hey Doddy! I’ve got a Rocky Mountain Fusion 30. It has an SR Suntour XCR 32 fork on the front. A Deore XT 1x10 drive train. I’ve upgraded the tires to tubeless and upgraded the peddles to good flats peddles. I’ve also added a dropper. What other upgrades would you recommend or would you just ride it till it’s worn out than upgrade the bike as a whole to something better?

the shifting system was made by a Chinese company called Wheeltop, which claims to be in the bike industry for a long time(though I've never heard it before here in CN), the price of GX AXS here is around 455 pounds and this is only 282 pounds. So it's actually made for people who wants E shifting for low prices.

[scchua]

Hi Doddy, Conor Dunne is a giant amongst the GCN presenters! LOL! I'd love to have you test the 36" wheels, but perhaps not on Conor's bike? 😂

[Paulklampeeps]

I saw one here in south east asia it's mainly on built bikes that cost 500- 800 dollars. The one that Doddy got is probably overpriced.
