KONA Curve Cranks

[Woodyuk]

Hi All


Quick question ...
I have a set of Knoa Curve Cranks with rings that I am thinking of adding to my Kona bike ...Does anyone have any info / opinion on these cranks eg.
What year were they produced
How do they rate as cranks in performance and weight etc


thanks for any info

Re:

they had been on the Kona bikes for the 96 season only.

some say that the cranks are soft as cheese and can break easily.

I have ridden that cranks on 2 of my Konas, without any failure, but maybe I didn't ride that hard to do any harm to the cranks.

Re:

I've not seen break, but make sure that the axle bolts are good and tight.

I worked in a Kona dealers in 1996...definitely soft as cheese. We had a lot of LH cranks (10+?) come loose and round out that year.

All the best,

Re:

In our shop they ended up sending us Sugino cranks to replace them. They are a touch soft and the tapers round and stretch. They are fine as long as the crank bolt never loosens, unfortunately the other problem with them is that the crank bolts tend to loosen....

Re:

They came stock on my 96 Sex One. Never bent them but I did have to shim the axles with bits of beer can to snug em up before they were swapped out. They also survived 3 sets of chain rings and my introduction into jumps and drops in the late 90's. So I would say they are strong enough for me, although they did wallow out eventually with hard use. For a light duty bike I'd give em a thumbs up!

Re:

The '96 Kilauea that i bought for my other half has these on. I wondered if the missing Curve decal from left crank arm meant it was a replacement part, but I see the OP's is the same.

I'll be checking crank bolts regularly based on advice above. Mrsthefish is small and light so hopefully the cranks will survive.

I have a set sitting on my kitchen table. I had no idea who spec'd them till now.
