Bashing cranks!

[Neg]

Interestingly I switched from a Spark Medium 26er to a Niner EMD9.

 

I'm hitting rocks probably around 90% less than what I did on my full suspension, with basically all my lines changing at GK to where the 26er would have hit rocks. Both cranks arms were the same length.

 

Also the Scott was a medium and the Niner is a Large.

 

Would like to ride with you sometime and learn from you, i am probably doing something wrong and cant figure it out on the 29er... while on the 26er i do better.... maybe i just need a pointers and all will be sorted! ??

So... it turns out i have a lack of talent... and a leaking shock..... was picking the wrong lines on the 29er.... mind shift for me is needed to take different lines. Odd though, the lines i used of the 26 work well.... oh and i need to get fitter... i'm fat and slow!!!

 

Thanks for the pointers and advise Dubber88. Sorry to have kept you waiting all the time!

Cool Cool. Glad I could help out.

After a couple of years riding you'll find that you'll be able to predict many pedalstrokes ahead of obstacles whether your cranks will touch rocks or whatnots. Then it'll be a case of stopping your pedaling for maybe 0.5 seconds - and then you can pedal straight through the obstacles without the cranks/pedals bashing.

Yeah- that's what Dubber showed me..... was great seeing a different Angle...

Sorry for the long winded explanation..... but.....

 

When I got my 29er, I sold the drivetrain- crank, cassette, chain front and rear derialures , which were shimano 2x10 and replaced with my older Sram. I was/am Very happy with the 29er but I notice that the cranks are lower than on the 26er and bash allot more than my 26er ever did. I did not want to believe it but this morning was forced to face reality…

 

Now I don’t know if the original cranks arms that came with the 29er were shorter than what I had on the 26er which I moved over after selling the 2x10... Today at Groenkloof, going up the section where those wood discs are laid down next to the rocky incline, I cleared the 1st rocky section and about 1/4^th up the next section. When I rode an anthem 26er last week I got almost up the whole section about ¾ the way up. What happened this morning was as I was climbing, my crank arm smashed into rock and the bike came to a sudden, solid halt! Got going again and it happened two or three times after that too… eventually I pushed the 29er where I was still peddling the 26er….

Truth be told though, I like the 29er, on normal rides its comfy and for me it feels quicker which helps with my “placebo effect” J and it would be great for me if I could just get that crank higher!

So…. Do I sell the Giant and try find something with a higher crank or put shorter cranks on…? I am 1.83m, ride a medium bike and I currently have 175mm (or something like that) XT cranks.

What would the implications be with the shorter crank arms, higher seat post and higher riding position? But what would it do to the actual pedaling? Shorter crank more or less torque… higher cadence to get the same speed from current set up…??

Im just SO gatvol of smashing the cranks!!!!

 

very easy solution is move back to the 26" cuz its just better!

As I'm looking into getting my own Anthem X29 1, I've read a fair amount of reviews and there is a couple of riders mentioning the crank hitting obstacles.

 

It seems most of the posts are from riders that converted from another platform or saying it was sorted out after time when they got accustomed to the different riding style.

 

I'm getting my Anthem this Friday...

After riding with Dubber and seeing a different approach, i will stay with the 29'er. i do prefer it to the 26er, i was just worried about the cranks bashing! but it just means i need to change riding style.
