What expensive stuff have you bought for your mountain bike? Was it worth the money? Share your thoughts! 💭

[@cegalleta]

A high POE does feel very nice, but the biggest expensive improvement was a good wheelset, definitely worth the money to have it custom built. Good forks are crazy expensive but it is what it is, buying used is scary since missing service intervals can really fuck up the finish on the stanchions.

[@fintancostello_ok]

Probably SRAM Axis. Given the fact they have basically removed the derailer hanger and made the thing wireless I’d say it would be worth it if you are having too many problems with your existing drive train.

[@garthflint]

I bought some Berd 29 wheels with I9 hubs for $2100 for my Scott Genius. Stupid expensive. Absolutely worth it if you can afford it. Totally changed the ride. I put AXS wireless shifting on the same bike. So so. I like it but worth $500 of like? I have carbon cranks with a Ti spindle. Only a weight weenie would bother. Save the money for those Berd's. Hope 4-pot brakes are a must have. I put them on all my bikes. I figure them into the cost of a new bike. Helmet. Cheap are like wearing a box. $300 is only 5% better than a $120 helmet and are no safer. For the regular rider $80 - $120 is the place to be. Riding shorts. I spend $100+ for my padded shorts. On a 6 hour ride I want my tushie comfortable. Good shorts last forever. I still ride in a pair of Cannondate $80 shorts bought in the '90s. In the '90s that was big bucks. Best shorts I have ever owned.

[@billydeewilliams8909]

Redshift shockstop suspension stem for my gravel bike. With cush core front and rear, I saved about $500 on a gravel fork. Carbon wheels for my e-bike. Leatt Enduro 4.0 convertible helmet. Outbound lighting set. Five sets of Crankbrothers Stamp 7 pedals. Milwaukee battery-powered inflator. Three Ergon SM Pro saddles.

@gmbntech better, I'm moving to Asheville NC to spend more time riding and less time working. Just have to sell my house first.

[@charleswinston2495]

I've never bought a bike I was 100% happy with as OEM stock. There's always something that makes it more comfortable or perform better, but these don't have to be super expensive. So I think the "is it worth it" debate is really a "does this improve my riding enjoyment sufficiently?" eg After one of Anna's recent videos on brake discs I upgraded the front disc on my 2-pot XTR brakes from 180 to 203, and it has improved my braking confidence hugely... For about £40. Against that, I ride XC to improve my fitness, and the c£850 upgrade to SRAM XX1 cranks with a Quarq spider power meter has also been really worth the investment in terms of extra training data. I'm sure many others wouldn't see the value and think that's bonkers... To me it's about making changes that have a real impact on my riding.

[@DieterVanHolder]

Having guided in really wet and windy climates for years, I was lucky to use some very expensive waterproofs. There's no rush thing as breathable and waterproof. The increase in value is in the quality of the materials (weight vs durability) and the comfort/cut of the item. More expensive brands usually deliver better looking and more comfortable stuff. But I've had €10 euro jackets that were just as waterproof as €700 jackets. I got wet in all of them.

[@iggalan]

There is a misconception that you can make a jacket both waterproof and breathable at the same time. This is not how things work, if it's raining the fabric will be waterproof but not breathable and when it's dry outside the fabric will be breathable. There are several videos showing you why, don't be fooled by marketing.

[@Straightcash8]

My dad worked in a bike shop for 20 years and had the best philosophy on buying helmets: Spend what you think your brain is worth.

[@gmbntech]

That would make a great poster to hang up behind every helmet display!

[@owenjacka2658]

Having worked in a factory that makes waterproof membrane material for clothing, medical and military stuff I can totally understand why good quality waterproof clothing is so expensive 💯

[@michalwiktorow2188]

S-Works Recon shoes - carbon sole + titanium plate and aluminium Boa knobs - totally worth it. Not only stiff as hell, easier to peddle but also really almost indestructible shoe. Then S-Works Prevail 2 (aramid) helmet - also so light and breezy. Third is Evoc e-Ride backpack - FR Trail e-Ride 20 - marvelous features. Worth every penny I've spent on them.

[@johnmuttitt]

My first mtb (early 90's was a bright yellow Peugeot Flame with the biopace set up. I loved the bike, but looking at what we have today, it was like a tank! It still made me smile and I enjoyed every ride.

[@luclachaine7849]

Got myself a custom titanium hardtail. Man, this bike fits me like a glove and tides like a dream. Got a set of eewings crank on there also. My these cranks are stiff!!!

[@steveyates2423]

Shimano Biopace - still got a set of 105 chainrings on a steel bike from the early 90's

[@user-yv2cz8oj1k]

'Oval' chainrings concept predates the Shimano version, the first 'elliptical' chainrings being in the 1890s. Because inventors where thinking of these ideas a long time ago.

[@teamfubar]

The Shimano oval chainrings are/were Biopace. My first 2 mountain bikes had Biopace chainrings (Trek 950 and a Fisher AL-1). The Sram AXS product is the first really expensive stuff I've bought that feels like it is worth it. I didn't think I'd like it nearly as much as I do. I find myself shifting far more frequently than I used to. Worth it to me.

[@captainchipowen5184]

Owen has it right as far as I'm concerned on the idea of $500. hubs. Marginal gain at best. Pride of ownership is the only vain reason for wasting hard earned money here. But, then again, I'm one whom said the same thing about a $200. saddle. Now, I'm the proud owner of two of them and I ride on a very happy butt!

[@iggalan]

$200 is quite a lot to pay for a saddle, but if that's what you need to enjoy your rides day after day, good on you!

[@tomrodgers6629]

Not at first look at full suspension that was crazy expensive at first now it is common place at a reasonable price point. (most of the time) 😁

[@matt_acton-varian]

Independent testing has proven that nearly all helmets fitted with a rotational impact protection system (either MIPS or equivalent) are significantly more effective at reducing impact forces than their non-MIPS counterparts.

[@JB50713]

Fox clothing is fairly expensive but damn it fits well for biking.

[@gregknipe8772]

good show here, I learned somethings, and I agree with your framework for value vs price, we each have different needs and budgets. withoutnthe leading edge out there, we see fewer real breakthroughs... thank you.

[@stocky1042]

Shimanos none round rings were called biopace. I actually have some back at my parents house 😂

[@cegalleta]

I got triggered as fuc when I saw the oversized pulley wheel, if you want good bearings (not necessarily ceramic), you want them in your hubs! Ceramic last waayy less than steel ones do because the ceramic is harder than the steel rail and cage and often erode them and develop play, steel wears out the cage and rail more evenly so it doesn't fail that abruptly. A good upgrade would be: Very good hub, no contact bearings in the inside, shielded bearings in the outside with light grease, since shitty seals and grease are often the cause of most friction on bearings.

[@duncanrosie1842]

Endo’d yesterday and pivoted over on my head. Expensive (for me) Leatt helmet totally worth it.

We'd rather break a helmet than our head 🤯 Hope you're all good! 🤙

[@unclewickedmtb2023]

Buy the best helmet you can afford. I even subscribe to, buy the best fitting and most feature rich helmet you can. After some ugly concussions, I don’t hesitate to put my family in the best helmets I can. Fly RHEON is arguably some of the best concussion prevention technology, as is 6D’s multidirectional technology. 💪🏼

[@justsayin3600]

Facts!

[@gmbntech]

You only get one head!

[@toxicmale1744]

ABEC5 bearings in the hubs, bottom bracket and headset makes a big difference and is well worth the money. Enduro bearings for the rear if it's a full suspension is also prudent for the money.

[@petersouthernboy6327]

Enduro races wear out incredibly fast

[@seansamurai1981]

In regards to helmets. The same goes into motorcycle helmets, you can buy cheap ones that meet the proper ECE standards and few others but the fit is always hit and miss, shape is a big one. Cheap helmets tend to be quite round. The more expensive you go the better the shape, more sizes, different shell sizes to keep wind resistance lower, better internal materials, lower weight etc. So I always go with the addage, pay highest you can afford on a helmet. Shimano Biopace by the way ;)

[@jacksondaniels8169]

The I9 hubs are sweet. Saving up for mine as I speak.

[@max-eb9vi]

After much much research. I run a leatt 8.5 moto x helmet for dh and bike parks and gyro tyrant for enduro and trail riding. Basically if you get a full face make sure its ece 22.06 cert and a half face id say go with mips (spherical if possible) and has an adjuster so you can tune it perfectly for your head size. Fit is very important and replace every 3 to 4 years if not crashed. Helmets are cheap compared to brain damage

[@user-yv2cz8oj1k]

Bearings: I have a bike that has a roller bearing bottom bracket. It's extremely smooth and locks the crank in nicely as they are in a cone arrangement. But would I want them in the hubs? No, as the benefits of roller bearing hubs on a MTB would be minimal, and due to the extra forces placed on a hub they could be detrimental compared to their use on a road bike.

[@user-yv2cz8oj1k]

There was already a 3 speed planetary with 7 speed derailleur rear hub. It definitely has been a thing in the past.

[@mtbboy1993]

4:26 I've never invested in a expensive water/wind proof kit, as it's expensive and a crash might ruin it. Currently I have kit from Endura, but the fit is not made for an regular human. Made for stick arms, and monster knees. But I stayed warm, dry, rode in snow, brutal rain, and winds. But had to go for 3XL jacket and L trousers as it has 82cm inseam, but the waist was massive, 4 fingers worth of extra room, so belt was needed. But looks like I'm Small in gloves, not tried it, Medium was too big, but good for thick wool liner underneath. Hood on the jacket was so big it covered my face, but the sleeves fit, armpit, bicep area was big enough, so was the sleeve hole, so I fit wrist braces trough it easily, but stomach was baggy. It was a weird fit, but was cheap, and was in somewhat my size, and had the features I wanted and was in stock. But definitely not ultimate kit. But it was the fist waterproof riding kit I bought.

[@danielburke7012]

6:36 I like my friends take on a helmet. As long as the helmet costs less than the medical bill if you don't wear one it is worth it.

[@patrickmoore6351]

Shoes. Can’t say it enough. Whether you ride flat or clipless, get some comfortable shoes that grip really well, regardless of if they “look cool” or not.

Helmets-look into the Virgina Tech testing. The top rated helmets are not the most expensive.

[@DamianMTBintheLakes]

In answer to your oval crank question, my first MTB had Shimano Biopace cranks, that would have been around 1990 but I think they released them in ‘86? I liked them but after all the negative hype about being bad for your knees I’ve not used them since 😢what is the current industry information on oval cranks? Any good? Knee killers? Also, on the helmet front, I’ve just bought a bx full face for £20 in the chain reaction sale. It’s CE approved and fits well, my pal spent £200 on a TLD which looks fantastic, but is built to the same safety standard and, correct me if I’m wrong, but they’re both only good for one crash?

Probably SRAM Axis. Given the fact they have basically removed the derailer hanger and made the thing wireless I’d say it would be worth it if you are having too many problems with your existing drive train.

[@peggz223]

‘SRAM T-Type groupsets are 100% ‘set it and forget it’. Once it shifts well, all you gotta check is chain and cassette wear, and it will always shift well.

[@iggalan]

The problem that I have with wireless derailleurs on MTB is that eventually you'll smack it with a rock or something and it's too expensive. Sometimes good enough is good enough 😀. Until internal shifting (either in the hub or as a gear box) are a thing I'll stick to cable actuated ones.

[@petersouthernboy6327]

I have nothing but praise for SRAM electronic shifting

[@peggz223]

@@iggalan from what I’ve seen as a novice shop mechanic, legitimately 9/10 times that there’s intense and sudden shifting issues on a bike, it’s the $20 hangar that needs replacing, heavy derailleur damage is actually fairly uncommon (unless you get super unlucky with crappy line choice out on the trail). If we’re talking the super bougie SRAM T-Type systems? Virtually bomb proof. ‘Buy once, cry once’, they rarely have mechanical issues that result in pricey replacements.

I’m with you on a lot of stuff but the ball bearings are not hard to make. If you want a really good bearing for a bike get taper bearings A lot more of engineering and machinery is in a tapered bearing than a ball bearing.

[@mtbboy1993]

6:16 I think every helmet will feel like it fits badly if you ride in low sub zero temps like -10C, all of helmets I had shrunk making them tighter at the jaw. So I definitely feel it then. 2016 Fox Rampage Pro carbon did it, and now Leatt Gravity 1.0 DH does it too. 6:49 Leatt Gravity 1.0 DH is lighter than most carbon full face helmets, but I don't know how it translates to safety. But a con with that helmet is the visor is not movable, and it's too high, so it's redundant when you actually need it. But it was cheap and light. But Velcro adhesive pads loosened, but I replaced it with 3m VHB. 2016 Fox Rampage Pro carbon was expensive and much heavier, and cheek pads wore out in few months got so squeezed the helmet slapped me in the face. Some claimed new Rampage Carbon does not have that issue, but not tried it.

[@lemeneid]

Anything to do with safety I don’t compromise. The best helmets, sunglasses, radar unit, etc… Everything else, I buy based on what I am willing to pay for.

[@charleswinston2495]

Re the i9 hubs. My (limited) understanding is that better rear hubs are lighter, built better / last longer and have more points of engagement. I understand the lighter / built better qualities, but outside of competitive XC racing, has anyone noticed if they have 1, 5 or 10 degrees of pedal travel before pick up? My hubs have 36 points of engagement, but there's usually so much to think about when out riding, I can't say I've ever noticed the implied 10 degrees of pedal travel before pick up. Am I missing something?

[@michaelrodgers5105]

My 29" bike has Hope pro 4s hubs on it. Which is 8.4 degrees My 27.5" bike has Profile Racing Elite hubs on it. They are 1.75 degrees. I definitely feel the difference.

You can definitely feel the difference. Will that make you faster? It's so marginal that for most of us is irrelevant.

MIPS has been shown to reduce concussion so for me that is worth it. A helmet is better than no helmet. Helmet that fits is better than any old one. MIPS is best (or WaveCell).

[@justsayin3600]

I'm convinced that MIPS work! I had a bad crash, flipped in the air, and slammed my head at about 6 feet. I slammed my head so hard, that I felt it instantaneously. I walked away from it without any symptoms of concussion. I'm convinced that MIPS worked as designed. The other thing to think about is full face vs half face. Granted a half face will protect the head but I saw a CAT 1 racer crash on a local run ( not racing) and he had, gravel, and sand embedded on the whole side of his face. After I saw this I never ride fast tech without a full face.

[@45graham45]

For anyone thinking about waterproofs please don't say things like "waterproof and breathable" as that's just marketing and the truth isn't "and" sadly it's waterproof "or" breathable.

[@slavnyan1152]

Wanted to say exactly that. Did you watch FortNine's video on this?

[@45graham45]

Well, actually, no jacket is ,"breathable" as that very term is pure marketing speak. The only way to breath is with lungs. Jackets have no lungs. The correct term should be something like air permeable.

[@optimoespacio]

Exactly, you can get a jacket that’s waterproof when it’s raining and breathable when it’s not. But it won’t be waterproof and breathable at the same time.

[@vilimiryordanov8502]

Building physics background here. Membranes installed on external walls and roofs are designed to be waterproof and vapour permeable. Some are air permeable and some are air impermeable. So yes, waterproof and air permeable (i.e. breathable) is definitely a thing. Most membranes that achieve this are microporous: they have small holes (on micron levels) which allows air and vapour to pass through. They rely on surface tension to hold water out. The problem comes when that surface tension is broken via surfactants or oils, then water starts leaking through. Best example of this is sitting in a tent while it is raining. No rain comes through but if you touch the fabric your hand gets wet.

The process of forming and curing ceramics from the raw silicates takes a few weeks. It's a different process to making your tableware, which takes less than a week and has a different finish.

[@feedbackzaloop]

@@matt_acton-varian sure, but here we are talking not few weeks, but two months, plus-minus (also, why 30% variance). Do they account production of both races in succesion? Also I was convinced CS use hybrid ceramics with nylon matrix - those are cast at rate of minutes

[@matt_acton-varian]

@@feedbackzaloop I would not have thought a nylon matrix as a durable enough material - CeramicSpeed and other high end ceramic bearing manufacturers offer a lifetime warranty (providing they are properly maintained which generally all moving parts should be serviced at certain intervals anyway) so would need something extremely durable.

[@feedbackzaloop]

@@matt_acton-varian well, it's a matrix, its durability must be with regards to fatigue, which is plenty enough. The alumina or zirconia cristallic inclusions are what is responsible for wear resistance. Meanwhile the bearings shown have steel races, so, yeah...

A lot of helmet "science" is questionable at best. Any standard that isn't EN 1078 / EN 1080 is likely to be funded by the manufacturer (eg MIPS).

Are there any helmets that fit a 65 c.m. head size

That's a XL. Some helmets have pads to adjust the fit. If it feels a little tight the pads will compress as you wear it. My Fox Rampage Pro Carbon was really tight in the cheek pads, and there is no smaller replacement. I just took them out, put a towel over the top, and tapped it with a ball peen hammer. It compressed the foam enough where it's comfortable. If you can't find your size in MTB go to an enduro motorcycle helmet. Those go up to XXL. It's better to wear a helmet than not. You can get them in a mat color, and not shiny clear coat. Edit: Motorcycle Dirt Helmet.

I9 hubs sound good on paper, when you look at the amount of failures of axles due to the torsion flex designed into the hub.. They really aren't worth the hassle for the amount you spend on them. My god they sound good though lol

[@Trikk57]

Goretex is another global dupe... FortNine did a great video on Goretex... Don't pay for the name, buy something else..

[@andrewince8824]

One just needs to look at the amount of material, or lack of, creating the engagement on an I9 to figure it's not going to be particularly strong.

[@JuanMendoza-yk8nv]

Any recommendation of hubs?

[@alank808]

a good seat and bars will do it. All the hype here is ?

Remember kids, ceramic bearings are a scam.

Where’s doddy gone

[@bikedude019]

All useless… ceramic material, fancy clothings and gears, higher poe hubs, power monitoring, carbon fiber parts will not make you faster. Spend more time riding will make a difference thought. Loic Bruni will still beat me on a entry level mtn bike from Amazon. Finally, the most ridiculous IMO is the oval chainring, as none UCI xcountry riders use them.

[@massimomusto1975]

I agree with you except for the clothing, sometimes it makes the difference

What is a power meter

You don't realise how close you are to answer your own question :'D

[@aleksarajkovic3471]

I9 definitely not worth it lol, famous for rear hubs breaking while internal parts cost more than a whole dt 240 hub XD

[@miyui9269]

they are only worth the money if you dont know where to spend all your money or if you are a really promising, very talented athlete. other than that these are a total waste of money.

[@LaurentiusTriarius]

You found the subject to get keyboards going in the comment section, anyway I actually find that most of MTB components are way out of wack pricing wise, brands like 5devs are criminals, kinda 😂 Anyway I vote with my dollars just bought another set of Chinese carbon wheels 🎉
