I agree. If not then the limit should be more. My S2 has been at min insertion since I've owned it, and no problems. It's exactly where I need it with the 54cm frame.

adriano 

thats fine, but thats not under twenty, and it doesnt fit to nearly you as well, hopefully.

i roll out with four pounds of water anyway.

adriano 

if anything, a cut post would improve ride. unless the excess extended all the way to the bb, which is ridiculous but would affect stiffness a bit.

ruskko

yea i do lol idk where to start i know my wheels are prolly heavy,but i know for sure that my seatpost and my pedals are pigs

ruskko

just shaved 28g off my seat post **** this thing is a pig 296g when i started

renegaderider

How do you determine minimum set post insertion length? I'll be cutting mine...

ruskko

should have a marking on the seatpost where that point is

mazdaspeed

I've heard the bottom of the post should be below the bottom of the top tube but who knows

ruskko

the min on my seat post was 4inchs

adriano 

thats pretty conservative.

Soloist Assassin

Granted this post has been tuned down a bit. About 40g lighter than stock with different parts, dremel work, and ti hardware. I think a lighter post would be a good start.

Soloist Assassin

I would think if the seatpost being at min insertion affects the ride of the bike, then clearly the frame is poorly designed if it uses the post to increase the stiffness. Just for reference Cervelo S series post min insertion is not marked, and it is 65mm. Or exactly where my tape is.

I'm cutting it tomorrow. I should be under 16 at that point...everything else is a bonus.

ruskko

which one do you think?i dont think i wanna go carbon.i was thinking either a zipp sl or thomson

Soloist Assassin

Neither of those. I have both of them, and they are heavy. Go with a KCNC Ti Pro Lite. Bang for the buck it is the best. I own one of those too. haha.

A few new things for the Litespeed:

SRAM Red Black 172.5 53/39


Compliments of Runningdoc (thanks again)



Planet X CNC w/ Swissstop & Hardware


Slowly, it'll get there...

ruskko

i need setback thou

DropDeadFred

cut 3" off my seat post .03 kg and put the TI speedplays on...my bike is at 15.75lbs before i put my 90mm zipp service course sl on

adriano 

the purpose of that other thread was just to justify a shorter reach, which will cost you more drag than the zipps save you but is certainly 0.05 pounds lighter.

DropDeadFred

you aren't understand that I'm slamming the stem, which creates more reach, bringing it in a bit compensates for that. The brand or the fact that it is lighter has nothing to do with why I'm going 90mm. I could get a 110 or 100. we ordered the 100 to begin with but decided to have it changed to 90 since we'll be dropping it. This from the guy that manages my LBS and did my fit.

DropDeadFred

im essentially keeping the 110 by going with a 90

DropDeadFred

now I don't know if thats totally correct but in theory thats how it should work and feel considering my arse wont be moving.

DropDeadFred

SA how do you compare the braking performance of the KCNC compared to the DA brakes Im running now? Weight savings?

adriano 

that guy also put you at kops, haha. if you use your drops at all, thats 120mm lower so dont sweat vertical reach. if you go uphill quickly at all, you wont want to sacrifice 20mm of longitudinal reach.

its 90mm, 0 degree? 55.5mm toptube and 90mm stem would work if you were quite short, maybe 5'6".

i bet moving your saddle down and back and same stem slammed will solve all your problems. just my thoughts. do your thing.

Soloist Assassin

Never used Dura Ace, but they stop as well as my Ultegra, and Force brakes. I weigh 71kgs, so I don't push brakes too hard. As for the weight, they will probably cut close to 100g off of Dura Ace. Just for the record The SS pads were 12g more than the KCNC pads.



As for my ongoing project. I got this pic from Slovenia this morning. My post is the one on top.
