you don't want to use what is pretty much the best XC fork around and you do want to use flat pedals? :roll:

A couple of questions out of curiocity:

- You say that the Lefty is "not for you", - what is it about the Lefty you do not like?

- Why would you choose flats for a XC race bike?

Martin F: 80g steerer, 80g stem and 65g handlebar. My combo is lighter then, with a Poseidon handlebar at 600mm. so could be even lighter with a slimmer Hera. ;)

I lol'd @ flat pedals. I can understand wanting to use a conventional fork, but flat pedals on a race bike would be pretty silly.

if the lefty was the best fork it would be the only fork available on the market.

i have looked at it many times before i tried it.
and i like the non-standard way it looks
but it just is not for me.
most of the time, i ride the bike i use now with the fork locked out
i will take a photo of the pedals i am using now and post it.
when i get time.

Biggest load of crap I have ever heard!
Let's just say the Lefty is the best XC fork available (don't want to argue the point, just let's agree for the argument), with you logic all other manufactures would just get out of the XC fork market. Not strive to produce a better fork and take the number 1 place. Also, even if the Lefty is better than others, it is also more expensive than many and (I believe) requires more maintenance than many. Not everyone can afford to have the best nor need the best.
This would apply to any product in the market place.
BTW most money is made in the high volume low to mid range products. Top of the line products are only really there as Halo products to attract people to the brand and have something to aspire too, but that the masses will never have any real hope of owning.
