The World’s LIGHTEST Alloy GRAVEL Crankset?

[@sergeypavliuk2634]

Super light enough! And it looks very harmonious as well, awesome!

[@KNURKonesur]

Looks very nice, damn! I'm too heavy for it to make any difference, and would love to see more "the world's most BOMBPROOF gravel crankset that's still decently light" :D

[@weatheranddarkness]

What are you doing on a "gravel" ride that you need a "bombproof" crank?

[@KNURKonesur]

@weatheranddarkness it's not a matter of one gravel ride. It's a matter of hundreds of gravel rides with a lot of weight on the bike and on the pedals. I already ruined 2 GRX cranks in 2 years.

[@weatheranddarkness]

@@KNURKonesur oh yeah? What was the failure mode(s)?

[@KNURKonesur]

@@weatheranddarkness spindle teeth ground down so the non drive crank would start slipping

[@weatheranddarkness]

@@KNURKonesur both times? Well, you probably would be well served by a 30mm spindle like this, there's far more surface area and the stresses are also better distributed by the lobes than by the finer splines.

[@Radelbande]

That's exactly the combination I have on my Titanium bike. awesome, super stiff cranks and looks are great!

[@lolbubs11111]

Love the Crux, hope you enjoy riding it.

[@bobtilton3024]

Awesome - welcome to the Crux side! Sending vid link to group text (Mammoth Tuff recipients) one of which was your fellow Outback riding buddy during the event. Looking forward to Crux vids - love mine.

[@Shaku4Shintai]

Just noticed your t-shirt! I haven't seen Poway referenced in a long time. I lived their twice in my life! Interesting crank, I like that there's even a 2x spider option on their site as well.

[@alexpina7385]

Nice install video! I've been running their mtb crank mounted to a Wolf Tooth Spider/Chainring on my Anthem for a season (paired with their 11sp mtb cassette), I dont notice a diffence between that and the RF turbine it replaced, but its a super clean/great looking crankset and lighter/cheaper than RF carbon options. I too had the same spacer issues as you - instructions said no spacer, but i had to run 2mm driveside to to get proper clearance.

[@E.T_rode_bikes_As_well]

M7100 165mm crank + garbaruk Dm chainring has been my go to for years now on gravel bikes. 2mm difference in chainline but works nice and a wider q factor is a bonus.

[@thedownunderverse]

Will it fit on bikes with “road” spaced bottom brackets though??

[@E.T_rode_bikes_As_well]

@ just add some washers and all good.

[@daniellarson3068]

Looks nice - I do wonder about the longevity of an alloy (aluminum) chain ring with all that metal removed.

[@garyaland]

The Crux is an awesome frame, you will love how it rides and performs.....

[@TheBikeSauce]

Is a rocket, but stiff. I’ve been reaching for it the most recently

[@slantedorbit]

My lightest bike is 22 lb and I’ve been perfectly happy with it as is, but pointing out that it’s possible to remove whole pounds off a build like mine hits home. The flip side is dollars per ounce of course. Nice to have options if I ever want to go there.

[@TheBikeSauce]

Going from 22lb to 17lb isn’t going to make you that much faster, if at all. It’s definitely a different experience riding a light bike though. Fun, but not necessary

[@slantedorbit]

@@TheBikeSauce Thanks, I appreciate that. 🙂 Elegant build, well done.

[@hardmtnbiker]

38t is perfect for my 1x gravel bike paired to my 11-46. I may upgrade my 11spd GRX derailer with the Garbaruk cage but I’m more interested in getting those XC cranks for one of my Mtn bikes. As you know Garbaruk offers them in many different color combinations.

[@aaronedgeart]

Love my Crux and yours is amazing.

[@grahamelliott6041]

What type of alloy, steel, titanium, magnesium, or aluminium ?

[@hinrichaue7199]

THANK YOU

[@TheBikeSauce]

I mentioned that it was 7075-T651 alloy which implies aluminum. If you're curious, there's no such thing as 7075 steel, Ti, or magnesium alloy. Cheers!

[@grahamelliott6041]

@@TheBikeSauce there are too many cycling videos and magazines that use the word alloy when they mean aluminium alloy

[@TheBikeSauce]

For sure. There’s a ton of that in cycling. We still call it a bottom bracket when it has nothing to do with a bracket. We call them braze-ons for carbon bikes, which isn’t a thing either. We call it a thru axle, when we really mean thru axle skewer, etc.

[@hinrichaue7199]

@TheBikeSauce that's ok for me, me as a non native speaker would you say saying alloy synonymously for aluminum is common language m seriously asking.

[@WashichawbachaW]

just an advise, put the bike on the ground when you're putting down torque on the crankarms. just to pull the stress away from your seatpost

[@weatheranddarkness]

Had the same thought. I was far less worried about the crank arms than I was about the post and frame being torqued on.

[@TheBikeSauce]

Good call, but I was applying a counter torque to the other arm. Didn’t feel much load on the frame

[@patricksawrey4743]

Riding the bike on the saddle will provide more force anyways.

[@veganpotterthevegan]

Really no sense in doing that for this scenario. Its worth doing for threaded bbs though.

[@weatheranddarkness]

@@veganpotterthevegan but it is threaded

[@thewintersteiner]

1:50 looks good even without considering weight

[@jakew8553]

I'm looking forward to the crux review. Is that video dropping soon?

[@TheBikeSauce]

Got a few in the pipeline first, but the crux vids are no my short list

[@kuri8015]

Please use kgs on screen too. It looks like a great bike

[@ninone23]

Super sick build. Soo much sauce! If I shaved 453 grams off my midsection would it have a direct effect on my performance?

[@TheBikeSauce]

Definitely 😆. But that’s harder to do, so we pay for lighter components

[@veganpotterthevegan]

Eat less and the money you save can buy these cranks.

[@lichray]

FSA's Energy Modular Hollow Forged crank arms are $100 on Amazon, 500g, 38t DM chainring from PASS QUEST, 78g for $48, $1/gram weight saving.

[@subliminalfreedom]

How do they bond it? Regardless it's beautiful.

[@thedownunderverse]

Shame shimano doesn’t do the 800 series cranks in 165mm. I too am running 600 series for this reason. I don’t see a reason to switch to anything lighter - I actually run garbaruk GRX 38t chainring on mine and they are excellent!

[@HeyWattsUpCycling]

wow thats light! if id know about this I might have gone with it over my 539g carbon 46t for my "weight weenie fast gravel" build im doing. tho it is 2.5x the price of the carbon one.

[@vbnxt]

Is the Crux more aggressive than the Diverge,,, would it be possible to be comfy on the Crux?

[@TheBikeSauce]

More aggressive than diverge for sure. Much stiffer too. I wouldn’t say it’s a comfortable ride, especially coming from the steel ritchey outback. Cruz is built for stiffness and speed

[@Jacob99174]

This channel sponsored by Garbaruk!!!! C’mon! 😂😂😂

[@TheBikeSauce]

I wish 😀. Just a fan over here

[@RomanoCortesJorge]

Garbaruk has a 10-52 11-speed cassette for GRX? I have their 11-50 Shimano compatible cassette for my 11-speed GRX, but if they have a 10-52 cassette for GRX, then I'm all for it. Can I just install the 12-speed Garbaruk cassette on my 11-speed GRX Di2 with Garbaruk long cage and just mess with the limit screws?

[@TheBikeSauce]

They do have 10-52! As far as mixing and matching 11/12 speed stuff w Di2, not sure

[@RomanoCortesJorge]

@@TheBikeSauce The Garbaruk website only lists--for 11-speed--an 11-50 cassette for Shimano free hub and a 10-50 cassette for Sram free hub. The 11-52 cassette is listed under 12-speed at the Garbaruk website. 😞

[@musclelessfitness2045]

Can we install this new crankset on a road bike? Also, is it possible to install the older GRX crankset on a road bike which has Shimano 105 components?

[@weatheranddarkness]

Yes and yes.

[@n0ch91c3s]

GRX cranksets have a 3.5mm wider chainline than Shimano road cranksets. A 105 front derailleur may not have the lateral adjustment range to accommodate it.

[@musclelessfitness2045]

Thx guys

[@jonathanwoo6597]

Just an FYI. Specialized frames from the factory are not compatible with a 30mm axle. This is because the frame is only faced to 41mm at the BB. 30mm axles require BSA30 BB which is usually 45mm in diameter. I had to face my Tarmac SL8 with a Park Tool facer which has a 46mm diameter. Watch this video clip for more details on this issue. kzbin.info/www/bejne/nWWugalsoLl8epIsi=v7ITk3cG0TgVLthp&t=573

[@One_mole_worth]

Guarantee it will be ok with out being faced

[@TheBikeSauce]

Been ok so far, but good info to know 🤘

[@peterliljebladh]

How many watts does the manufacturer claim these can withstand?

[@TheBikeSauce]

Eh, I haven’t seen any mnfr claim a max watts spec. If you’re putting down 2000 watts, then maybe call the company first.

[@orsations]

You are not a weightweenie, but you are becoming weightcurious.

[@TheBikeSauce]

😆 guilty

[@HGQjazz]

how much for that gold colored crank insert?

[@weatheranddarkness]

It's included and you pick your colour when you order. They're all the same price. If you want to change later I think they charge about 20$, or £. Somewhere in that ballpark for replacements.

[@hinrichaue7199]

I know I am splitting hairs... but alloy is not aluminum. I am sure, it is an aluminum alloy. but steel is also an alloy. Is it just me or is the use of "alloy" synonymously to aluminum so common that I just have to ignore it? I'm fine with that.

[@TheBikeSauce]

But these cranks are alloy. 7075 aluminum alloy to be specific.

[@TheBikeSauce]

Alloy and aluminum are not synonymous, but some alloys are aluminum and some aluminums are alloys

[@plepgeat]

If it works and it's pretty, it's justified!

So that’s the road and gravel cranks. But this one is actually the XC arms (165) with the road spindle

[@KNURKonesur]

If you want to shave another 150g off the build, can't go wrong with Tufo (Swampero) tyres

[@yumyumhungry]

100g of weight savings is pretty good. If you can find 7 places to reduce 100g that's 2 lbs. Not bad.

[@weatheranddarkness]

your math's a bit off. 1lb is 454g, so more like 9 places.

[@benzzoy]

Two halves of 7075 aluminum bonded together…hmm…can we say Magic Motorcycle crank from the 90s? Didn't that suffer from bonding issues? Come to think of it, didn't Shimano also suffer from bonding issues with their Hollowtech cranks? I guess time will tell if Garbaruk does any better.

[@petesjk]

The GRX is also a Hollowtech crank. Haven’t heard complaints about it. Hollowtech has been around since the 1990’s. On the whole, they have been some of Shimano’s best cranks. The DuraAce cranks with issues had way too many seams and not enough qc on required tolerances.

[@weatheranddarkness]

@@petesjk Most of the Shimano ones have been welded. They did have issues when they moved to bonding on the DA9000, but looking at the inner portion it's not surprising, the finish and clearances on the interfacing portions of the failed units were sub optimal. On the other side, Cannondale has had very very few issues with their bonded cranks, and they've made orders of magnitude more than Alex Pong ever did including both his time independent and under C'dale. Adhesives have changed a lot since 92.

[@TheBikeSauce]

The recent Ultegra and DuraAce has issues

[@n0ch91c3s]

​@@weatheranddarknessonly Dura Ace 9sp and 10sp (and XTR through 10sp I believe) were welded. All lower level cranks were hot forged as an open ended tube and pinched shut at the pedal and. Dura Ace 9000 was Shimano's first with bonded arms, with Ultegra R8000 getting the bonded treatment on the right arm only. XTR also had bonded arms around that time...

No chance I'm pretty p*ssed already about having 4 different standards of chainring mount type. 😂

This uses the same as Cannondale. But they make their own ring for this crank because it's designed around using external BBs so it has to offset the other way to compensate for correct chainline.

who said weight not matter? that word is blasphemy for weight whiny if it does not matter why so people love light weight bike even pro love it? because they pay, they feel and they all agree light weight bike is fun, it fast, agile, easy to control, and it take less energy to run. i did ultra many time and i am confess total weight is matter. between bring 10 kilo bike with all packing vs 16-18kilo bike with packing it is matter it huge factor, 10 kilo bike will climb more easy and it will be less torture people who said this weight is not matter is commit blasphemy, thing about weight i believe it because they never try sub 6 bike. or they never do self support long journey with light bike. the matter is the part quality. and i believe garbaruk since i used their ospw it work great and it is light it shift normal. they create great product.
