Having been in the automotive industry for 20+ years and dealing with oils, the MTB suspension companies are not making oils. They buy from an oil company and have the product private labeled. I also don't think they are custom blending suspension oils, just for their MTB products. They are probably purchasing an 'off the shelf' blend, that meets their requirements. Custom blending is not cheap, due to volume and minimum purchase quantities. Now you know.....>>>>

I really love the mood of this video : sitting in the wood while chill music plays. Really nice and relaxing.

Love how you cover all queries with such a depth of knowledge

Thank you for Fielding my question. I did forget to mention it was a full suspension and in particular I was wondering about spraying the pivot pulse.

Another belter of an episode :medal-yellow-first-red: - thanks for answering another one of my questions :face-blue-smiling:

I appreciate the MX talk as I was one of those kids in California for whom it was all the same, bicycles and motorcycles and the thrill of it all. And for a few years in my late teens in the '70s, I switched back and forth daily, even owning an early BMX import to West Germany and a '73 250cc Maico in '76 with my after-school job money. Plus I was street-legal with a 175cc Italian-made Harley-Davidson all-purpose bike, a decent street bike tho' it made a lot of racket with its two-stroke noise bouncing off buildings on narrow city streets. But I wasn't alone in that. Germany guys had to wait until they were 18 to be street-legal on 50cc two-strokes and talk about engine whine, they'd click through the gears, zing pause zing, and I'd hear them in bed late at night in Frankfurt and I'd smile in the darkness. We were all just looking for two-wheeled good times. 😀

9-46t is practically the same as 10-50/10-52t cassette. I need the range as I ride my bike on all sorts of terrain. Used to run 36/38t on 10-50t 12 speed but recently changed to 9-46t 11 speed cassette & now I run 30-34t chainring. Gained clearance and dropped in weight! Also less maintenance as 11 speed allows more margin of error

@owenbikenerd - you've grown so well into this role. Doing a heck of a job. Cheers

If one constantly uses both ends of big range cassettes, double is the way to go. Yes, they come with clutches and front derailleurs optimised for smaller chainrings now

400mm travel gogogogogo!

Looking abit cold there! Winters coming in fast here!

1x12 / 1x11 drivetrain with the big casette in the back are useful in certain situations. A 2x10 or a 2x11 have a wider range of gears to choose from. That being said, there are some combination of gears repeating, redundant. I have a 1x12 full susp and a 2x10 ht. I can go faster on the ht because I have a bigger chainring in the front. On the uphill, the gearing is similar. It really depends of your needs. If you climb more, a one by with a smaller chainring is better than a 2x. If you want a do it all bike, a 2x11 with a wide range casette might be the way to go, even for racing. All in all, it's up to personal preferences :D

I had a creaking frame. I could not for my life find it. But after regressing everything I could, it was still there. In the end it was sand that had found its way between the front gear and crank.

50T casette make sense with at least 34T front chainring. In my setup i've got 48-11T casette and 34T chainring. Another good side: standard 114 links chain fits perfectly without cutting. Previously i've got 42-11T and 32T chainrig - this was not perfect: because loosing some speed on flat sections. And wheel size matters - 50T/48T casette on 29" wheels make sense (because whel size) but on 27.5" or 26" - 42T should be fine...

Motorcross suspension needs more frequent servicing then every 50 hours! I would do my MX/Enduro suspension every 20-30 hours depending on what ive been riding. Mountain bike suspension service is going to vary a lot more base on riding type and location. If you ride up and down hill the service interval will be a lot longer then somebody catching lifts at a bike park.

Recommendation on my Nukeproof Mega 2020 rear rotor size only 160mm. I've tried putting on 180mm rotor and its touching inside of rear triangle. So sometimes it should be kept as recommended. Although I'm riding with 180mm, but knowing that it might cost me eventually. Or not. But i would recommend upgrading rotor size.

I run 10 - 45 cassettes and I live in the mountains with a 30 tooth or less chainring you absolutely don't need more than 45, unless you're carrying too much "baggages" 😂

If i followed the recommended lower leg service interval on my fork id be servicing the lower legs every three weeks. A bit ridiculous. I generally do a lower leg service every two months and a full service every six months.

Don’t just compare listed oil weights, but compare the viscosity. One companies “light” is another’s “medium” or “heavy”. Viscosity comparison charts are readily available online
