Strong freewheeling crankset

[Jackrabbit]

Agreed but I don't think either of those will fit for the same reason. A traditional hook spanner will work but if you're not careful you could easily damage the cups and it would be a bit of a pain to have to get another one.

The Pedro tool is the only one I can find that looks correct. I really only posted to alert others who want the kit that they will need a spanner type tool in order to fit it.

Got my Cyclone kit today. Looks good but I'm not sure how long the Dicta freewheel is going to last, it feels gritty already! Looks very easy to swap out though. My 8 point BB tool doesn't fit over the axle though so I need another tool to fit it. I'm thinking a simple hook spanner will probably work but if anyone knows of a better tool I'd be pleased to hear about it. What have others done?

I have a tool similar to the pedro's one, it's made in Italy by Roto/Cobra bicycle tools, got it yers ago for an extra long isis BB, having similar issues to yours with standard 8 prong tools, although this spanners type tools, as you mentioned, easily damages the cup's splines, this assumption is true mostly for 16 prong howitzer/gxp similar external cups that have rounded splines....the isis and 8 prong have 90° angle shaped splines, so this kind of tool works better.
A properly sized quality hook spanner, as you say, could do the job even better: if the cup is really tight....., at least, you will save 7 of the slpines, if something goes wrong :wink: .
I've never found a complete circle spanner for 8 prong, like some 16 ones, mostly because of the limitate request for it, but maybe also because the opened spanner tools are good enough for these cups.

I just used some vice grips to install the cyclone BB.

 

[crossbreak]

me too still got mine laying around since I changed it for a Hammerschmidt, if someone is interested PM me

Yes, there are problems only dismounting it, if for some reason, the cup is too much tight. Normally they are "friendly" cups

How much did you guys pay for shipping to the US? I just went to try to order on of the cyclone crank kits and its quoting me $117 shipping for a $117 part.!?!?!

Email Paco directly regarding shipping. He charged me about $30 shipping on my parts, if I remember correctly, to California.

I ordered the BECAUSE ISIS cranks. Probably the best deal in the US. I ordered trialtech cranks from trialspads.com but they werent in stock and got refunded.

Hoping they are good quality

I e-mailed him and he made me pay $117 shipping to Canada.

You will also need a special tool to remove the ISIS crank arms.

I ordered these caps to put on my existing crank removal tool: http://www.ebay.ca/itm/2pcs-Bicycle-bike-Bike-ISIS-CRNAK-CAP-Use-for-remover-ISIS-Crank-Black-cap-/261048174065

That's odd... he made you pay $117 shipped to Canada? It better have gotten there the next day.

Shipping took a while, and the assembly on mine was horrible. The "thread locked" bolts seem like they were just painted blue and not actually thread locked as they were all loose after the first ride, and I had to reassemble the chain rings with washers since the included spacers were different sizes and caused the inner chain rings to look bent when tightened down.

The outer chain ring seems to be made of pretty soft aluminum, I've lost a tooth on mine after dropping the chain and the teeth look pretty worn down after just 1 ride (too many amps for aluminum probably).

Still seems to be one of the better deals for a strong crankset.

Here's the best deal I can find on Pedro's 8-notch shimano wrench for these: http://www.ebay.ca/itm/Pedros-Bottom-Bracket-Wrench-Shimano-8-Notch-Flat-Wrench-For-8-Notch-Shimano-/350817376236

SickBikeParts.com has steel chainrings you can use in lieu of the aluminum one.

Thanks for the heads up, I'll grab theirs if I can't find a better deal since they want $42 for shipping to Canada!

I fitted the White industries Eno freewheel to my Cyclone kit today, its a direct replacement with no modifications. The quality is night and day with the Dicta unit that's supplied with the kit. It is expensive but if you are riding mainly off road or in really dusty conditions its probably worth it as the Dicta unit is unsealed and will wear very quickly.

 

[Chalo]

The bearing in a White Industries freewheel is of much higher quality than that in a traditional single freewheel, but it has only one row of balls. Off-axis loading in a freewheeled-crank setup will kill it, even though it is nice.

Freewheels, no matter how well made, are simply not designed to overrun while there is chain tension on them. Unfortunately, that's the way freewheel cranks work. The cure is to use a normal crank and appropriate reduction ratio, and pedal along when using motor power. But I guess that must be something only real cyclists can understand.

 

[Jackrabbit]

I don't understand maybe one day I can become a real cyclist.

 

[Chalo]

The notion that you might need to pedal to apply power is an idea that seems to escape some members here.

Or you could invent a one-way clutch that is reliable under full motor load. Pedaling along is easier, though.

 

[full-throttle]

Alright, enough of this crap.

Chalo, you might think you are a "real" cyclist, but you are NOT. So, stop fantasizing.
Pedal bikes can't apply power through the corners, so you got no idea of the benefits of doing so.

Read the 1st post in this thread. Pay particular attention to: 2) Provision for the inboard bearing. WI must have it.

So, what's you point?

Read the comments on the video. Most popular one:

This comment has received too many negative votes

As a motorcycle rider and from little experience (riding for a year) I know not to accelerate whilst cornering, surely these guys should know better?

Incorrect, I don't know who told you that, you DO accelerate while cornering. What you don't do is over accelerate. You either slowly accelerate through the turn or maintain speed. You DON'T brake. I mean, if you're a GP racer there are ways to brake but You and I don't brake. Braking o harsh acceleration changes the amount of pressure being applied to the tires which momentarily decreases friction. Accelerating perfectly evenly through the turn slowly creates more traction.

There is about 5 months of daily riding on my GNG/kona bike now.
It has between 2 and 4kw of power hitting the bicycle drivetrain all the time, since the only kind of driving i do is wheelies, full accelleration and a Little off-road.
The original GNG-freewheeling crankset shows no wear so far.
I almost never pedal.
Once the crankshaft was bent. It was after the bike took a flight and landed on one pedal. It was easily bent back with a hammer. Didnt have to take anything apart.
The GNG-support bearing seem to do it´s job.

Hi Christerljung

The GNG-support bearing seem to do it´s job.

Good point on the support bearing. I hope to add one back into my setup when it comes apart for inspection and service. This makes for a much more robust crank freewheel setup for certain.

As much as I love the way the gng powers up in what ever gear your in, the pleasant surprise for me is how amazing the bike feels when off the power. Totally silent and just a bit of noticeable extra weight in the middle of the bike, and all else is pure bicycle, the way it takes turns /single tracks, the way the wheels feel over bumps (suspends/ feeling of lightness) and the way it descends on twisting country roads. Most of these times I am only pedaling, to keep my legs from cramping, or to get my feet in a better position.

 

[skyungjae]

It was easily bent back with a hammer.

I'm glad to see that your Kona is working out well for you. Perhaps I should try and fix my old GNG BB spindle using the hammer method. :wink:

 

[speedmd]

This is the one I put in. No bend! Had to add a custom washer inside the cup so I could show some threads to use the gng lock ring.
