Weird crankset, it's GXP but has the NDS side bearing pinch bolts and BMX style chainring. Guess you don't have to respect the Shimano patent on that if you make a GXP crank in China. GXP was my favorite for awhile but I broke 2 right side crank arms because the metal on the S.300 is butter soft. Now I'm back on square taper Sugino 75s doubt I will be able to break them.
I keep hearing about shorter cranks might need to grab a set to try them.. I think they are called children cranks because kids usually have shorter legs and by adding shorter cranks they don't need to extend there legs as much
@@theshedMTB 35 Newton Meter is just right. If you put GXP on loose it will wear out the bearing race on the spindle pretty quickly. It won't be super quick because GXP uses a steel spindle, but if that was a modern crank with an Alu spindle it would be toast quick. I'd tighten it up to 35 NM and see if it spins well and the cranks have no side to side play. The range is 35-41, I had a GXP crank that snugged up perfect around 34, and I've had one that needed about 40. The key is to get it just tight enough so you aren't binding the NDS bearing with the wavy washer, but your crank has pinch bolts which is odd for GXP because Shimano has the patent on that. I'm guessing since you have pinch bolts you don't need a wavy washer and should put it on the minimum torque setting which is 34.
So here’s the thing I’ve seen other tests where they really compared head to head with different length cranks and I really don’t have the ability to do that right now. My wife is 5 ‘ 4”and she rode the bike with the 160 cranks and says she didn’t really feel any difference. But then when she got back on a bike at 170s, she could feel the difference and she felt she was more stable on the 160 cranks. I can only assume that it’s because when you got the cranks flat and your standing up on the pedals, you’re feet are closer together and it feels more stable. Hardtail Party did a really good comparison of different length cranks and there’s been other videos and he did way better job than I would be able to do!
@@theshedMTB cool! I’m looking to try 150mm cranks on my brother’s 26” bike. Also looking to try 1x10 with a decent chain line. Hopefully it’s just a matter of a spacer or two as you said in the video. It’s kinda hard to find a review on these products!
@@TheMXinsidE yeah mine was dead on 50 mm centerline, and I use the 3 mm offset adapter for the chain wheel. It was just weird that it took three spacers on the bottom bracket where I normally only run two .The main thing is just check everything as you’re putting it together.
I'm always right! Thats one thing the Wolftick dudes never seem to understand...😂😂😂😂 j/k I think what makes these childrens cranks is the fact that the back of the arms are very hollow, so probly not the strongest. I also saw a pick of a roadie who broke a set of these. Arm snapped in half just from pedaling a road bike?!?!?! Idk my legs aint that strong.
You can definitely tell they’re not as heavy duty as the JG cranks I had but they definitely seem like they should be OK. I couldn’t imagine breaking one, especially since it’s Tracy’s bike not mine.
So I’m 6 foot and I tried 165 cranks and I just couldn’t get used to them. They’re now on my sons bike who is like5’6 and he likes them. Tracy actually rode the bike with the 160 cranks and said she really couldn’t tell a difference!
I am 6 and for me 175 is just right. But it is a personal thing, I just happen to like a slightly lower cadence with slightly more torque. @@theshedMTB
Thanks for taking one for the team and buying and trying it out. I'm always a little leary about ordering stuff so it's great to see it in action!
You thinking about trying different cranks?
@@theshedMTB Not yet, mine are still doing the trick but it’s great to see it in action when you demo it 👍
@@spacesinbetweenproductions you could use a different cassette though! 11-48 give you allitle more climbing ability

Cool shirt , it’s great that your daughter is involved with your production .
It is great she’s involved in it! Although sometimes she wishes she wasn’t because the editing goes on longer than the filming sometimes!
@@theshedMTB oh the editing …the most work

I know, but labeling them that way made me think they may not work
Torque for the bearing loading is 3 Nm. Torque for the crank arm is 12 Nm
Good thing I didn’t go by what I was finding online because I was seeing things like 35 Newton meter that I knew was too much.

@@___Bebo___ im going to try that, but 35 seams like alot.
Would like to see the result of a performance test please. I’m considering getting these for my brothers bike for a higher range 1x setup

@@theshedMTB she will be fine. I would break them if I ran them on a hardtail i bet.
160mm is sooo short
My wifes only 5’4 so maybe good,so many opinions out there!
I got 160 on my DJ and 165 on all my Mtb's. I want 160's on my ebike for less pedal strikes tho. I got these cranks in 140 for my son.
