Shorter Crank Arms on Levo / Kenevo?

[Rob Rides EMTB]

@RobbieJay great shout. I’ll put something together.

Great stuff, I think that will be really useful. Knowing that actual Levo owners have tested these parts and are community recommend (could be a cheaper product, that out performs a big name brand) is really useful info.

As not all people's experiences are the same, is there a way of giving user ratings for a particular item?

Ecky thump, no kidding the original crank bolts are in there.
For those already changed (some multiple times ?) what grease are you using? Or copper ease?

Not ever having come across self extracting bolts before. My "normal bolts" arrived today along with everything else but guess my self extracting be here tomorrow. Can I assume the self extracting actually screw into the arm (prior to installation onto crank) as there is an outboard thread inside the new crank arms?

Hi UKPHOTO,
WH

Bryan is indeed very helpful guy.

In other news, would seem SRAM is "getting it" now and will be offering a range of EX crank arm lengths;

Good to see!
Here is the extract if anyone is interested

I will do some pics for you so you can see what you need to do.

Cheers mate.

Have removed non-chain side. Just chilling now.

Fitted new 36t chainring in mean time which was fiddly but painless.

You Sir are a bloody star!
Seeing as fave country ever lived is NZ and my family are from Wales, no surprise I guess ?

I'll wait for the self extracting bolts tomorrow and leave the normal ones.

Thanks again! Surely such concise information will assist others too ?

My recent pedal strike left me with a broken neck. When recovered I have fitted 165 XTs in place of the standard 170s. I have a 36" inseam so didn't want to go shorter. Anyway mine was more not looking where I was going more than anything else.

Anyone interested in a set of near mint e800 cranks?

Hope your healing ok dude

What's the difference in non vs self extracting bolts? Wondering what tool(s) is needed for each?

 

[Doomanic]

Normal bolts secure the crank arm to the bottom bracket. To remove the crank arm you would need an Allen key to undo the bolt and a crank puller/extractor to remove the crank from the BB. The crank puller would need a spanner to fit it to the crank and an Allen key to drive the centre bolt.

A self extracting bolt is essentially two bolts combined. A centre bolt that secures the crank to the BB and an outer bolt that secures the centre bolt to the crank arm but still allows it to rotate. When you undo the centre bolt, it pushes against the outer bolt which acts as a crank puller and removes the crank. Post #188 covers this very well.

Ta. So if I want to change the crank arms on my Kenevo, will I only need an 8mm Allen key to remove existing crank arms and then just the new ISIS crank arms and M15 self extracting bolts?

Basically yes. If you go back a couple pages in this thread Rob has a link to std bolts and Kiwi a link for self extracting ones.

@Kiwi in Wales In your post #98 above, you posted info for the self extracting bolts you found, but I am unable to grab a link from the photo. I may be missing it, but would you please repost a hot link that takes me to the merchant? Really appreciated the photos and info on your instructional Post #188. Thanks!

Thanks UKPHOTO, this is the Post #98 on Page 4 that I referred to, but seems to be a pic instead of a hot link. I’m a new member, so I’m assuming I’m either missing something or don’t know how to grab the link. Working with Brian at Dillglove on 152mm crank arms, but would rather use self,extracting bolts.

I'm just manually typed and searched within eBay app, easy.

We'll, she's all done.
No fan of alloys and the one crank arm had rubbish crank and pedal threads, but I believe I won in end.
No real test as of yet but round an undulating garden all seems good.

Let me know how you get on

I like your bike stand!!!
I have one exactly the same, I find it great for doing minor work on the bike like supporting the bike while cleaning it, cleaning and oiling the chain, checking air pressure in the tyres, checking chain wear, gear adjustment, rear brake adjustment etc,
Great piece of kit and inexpensive!

Will do mate.

Currently re-indexing gears. My middle gears seem excessive in their changing (but I'm being finicky).

As for stand, I reckon it's THE most useful bit of kit I've bought!

On another note, I'm loving the Crank Brothers large Stamps thus far.
Was running Specialized Bennies, but seeing as changed front chainring and crank arms I treated her to new pedals too (thin as, even more clearance ?).

Do you have a link to that stand? I could really use something like that for indoor work.

It says max weight 15kg is it ok with the 22 or so of the Levo?

These guys are also great for prices on tyres. I just purchased 2 x 2.8 Magic Mary SnakeSkin Apex Soft compound Addix for 43Euros each. If you spend over 100Euros you get free delivery although delivery is still under 6 Euros for anything under 100Euros

I use it all the time with no issues, make sure you are on a flat surface and obviously do not sit on your bike when it is on this stand....

The Miranda cranks on my Bosch felt like the pedal holes hadn't been tapped properly, especially the left hand threaded one. They certainly haven't got the same quality standards as Shimano.

 

[James_MTB]

I was speaking to a biker tester last night; he mentioned next year ebikes will be coming with shorter cranks and a DH rider had mentioned it was more difficult to balance with shorter cranks

Has anybody noticed the difference in balancing the bike? with the shorter stance\feet closer together.

 

[ccrdave]

going from 165 to 152 means your feet are 26mm closer together front to back but with the slightly wider Qfactor of the miranda cranks about 3-4mm a side your feet are also wider apart in a side to side direction
I doubt you would notice, I will let you know later my Miranda cranks just showed up in the post
