I have a 2000 Jekyll and I want to upgrade 2 things 1 is the headshok and the other is the crank.

1. The headshok I have read that I need a reducer like this http://www.pricepoint.com/detail/18...ane-Creek-Double-XC-2-Flush-Headset-Black.htm I am very confused at what shock will work with the Jekyll and not change the geometry of the bike does the shock need to be 100mm or 80mm this example shows the size as 80mm http://www.cambriabike.com/shopexd.asp?id=97171 am i looking at the right area for size?

2. Is the Crank I don't know what size I need for the bottom bracket I believe my tooth count is 22/32/44t but is it 170mm or 175mm like this http://www.cambriabike.com/shopexd.asp?id=101641&page=Race+Face+Evolve+Xc+Mountain+Bike+Cranks

Thanks for the info this is a 11 year old bike and I have never done anything to it, I will post some pictures when I get a couple of parts I just ordered for something else.

Got a 2002 Jekyll

I've been upgrading. I think it's the same frame. It's a large frame. The Crankset is 175mm. It takes a 68 mm by 113 bb.

As for the fork. If you want to use a standard fork (11/8), or a 1.5" for that matter you will need to change your headset. The Cannondale Headshok is proprietary. Another headset will fit but no othe steerer tubes wil fit in the Cannondale headset. Woodman and FSA make headsets for around $30. Chris King makes a more expensive one, around $90.

I just got a Fox Talas 90-130. I've been told that a centimeter or two won't make a difference in the geometry. Anything more will slacken the head angle noticeably.

Good luck

Thanks for the info, I just called Crane Creek and they said I would need for the fork change a headset ZS49-30 but the top of the fork might hit the frame. Don't really know what he was talking about I have read a lot of people change the headshok to standard and they use the shorty version, but since I have the 2000 frame I don't know if I need the shorty or the standard size.
