bolt is as tight as it will go - but the saddle is not even close to being secure (see gap).

mazdaspeed

That's really light. I guess DT shifters and light wheels will do that. My current guesstimate is over 19lbs for my bike... hardly weight weenie... maybe I should just leave the thread now, lol

ravenmore

No, they should work together. Something's not right. Can't really tell from the pic. Might take it in and have someone look at it.

ravenmore

It depends on the frame a lot. Mine is Tange 1 steel which was pretty top of the line for Tange back in the day. It was a light frame for back then. I lost a lot of weight when I put the EC90 fork on. DT shifters, light wheels, light bars, and light seat post - yeah, you can get surprisingly light with steel.

mazdaspeed

Ah, you must not have read all of what I wrote. I'm replacing the steel with an aluminum frame / carbon fork. Originally I wanted to put a carbon fork on my steel frame, but it has a JIS headset and I didn't want to deal with all of that, and I bought a frame/fork for the same price as it would have cost for a fork and headset for the steel frame. That alone should take 1.5-2lbs off what I had before (which was columbus tenax, probably heavier than tange 1). Anyhow, my real weight adder at this point is the dura ace / open pro wheels. I used the weight weenie spreadsheet using weights of things to the best of my knowledge and my estimate is about a pound higher than I want, but I haven't actually weighed anything yet as I don't have the frame in my possession nor a scale.

I could keep posting updates in the thread but I don't want to depress anyone by building a 18+lb bike, however inexpensive it may be.

I had a similar issue ...just take a zip tie and pull the rails of saddle together.
When the proper clearance is reached, tighten the saddle bolts and cut the zip tie.

ravenmore

Wow - seems like a pain. My lighter and cheaper KCNC was much easier to work with.

Beautiful.
Comfortable.

Interesting link for the "weenie" in us all...

My $80 KCNC seat post with my $35 saddle weigh in at 214 grams. Less money for both than the Fizik post alone and just a bit more in weight.

2ndGen

Is that the carbon saddle I saw posted here before?
How comfortable is it after 3 or 4 hours?
Is there a weight limit on the KCNC post?

ravenmore

Did a 3+ hour ride on the saddle this morning that was awesome. Weight limit on the post is around 220 for road riding I believe.

2ndGen

"If" I copied your set-up and went with a KCNC stem, I'd knock 300g off my bike for about $350.
But! I might lose a lot in ride quality for how I have my bike set up. Damn! It's tempting as all hell though.
I think I'm going to have to learn to live with a very comfortable (for aluminum) 16+lb bike for now.

I think I'm going to "buy" a 15lb bike next time!

But if I remember correctly, that saddle you posted was definitely hawt!

mazdaspeed

Approximately much weight would one save by cutting a 400mm aluminum seatpost down to 300mm?

2ndGen

Take the weight of that 400mm post and subtract 25% of the total weight.
Do you know it's weight by any chance?
What type of post is it (brand/model)?

mazdaspeed

Not quite

mazdaspeed

Oh well, instead of asking a bunch of questions I'm just going to start weighing and doing. We'll see what I can manage.

no - the issue is not that the rails are too far apart. the issue is that the rails are too small. the seatpost will clamp onto my selle italia saddle which has oval rails (similar to the carbon rails of ravenmore's one on the last page - they are taller than they are wide. but the new toupe saddle has round rails, and when i go to clamp it down, it doesn't get tight.


well, i got the USE alien one lightly used for $30 shipped... so i couldn't pass it up.

does anyone else reading this thread have an alien seatpost? if so, does your saddle have round or oval rails?

2ndGen

If we at least knew what kind of post it was, we could know what weight we're starting with.
Then, we could figure out give or take a few grams what you'd end up with.
Different models of aluminum posts have different weight/thicknesses/builds, etc...

2ndGen

I don't have any experience with an Alien post, but do have oval rails.
At my request, Fizik sent me a list of which posts were compatible with oval rails.
I believe our rails are identical (since Selle owns Fizik).

I went with a Fizik Cyrano Post. Was going to finally settle on the aluminum version (even though
I wanted a carbon post), but just before I pulled the trigger on one, Fizik released their carbon version.
I went with Fizik for peace of mind. Carbon rails could be finicky.
I paid a lot for my saddle. I wanted to make sure it wouldn't be compromised.

I'll see if I can dig it up for you...BRB.

Response from Fizik:

"7x9mm saddle rail / seatpost clamps compatibility guideline

Please open the attached photo.

There is 5 types of seatpost clamps represented:

Type A: Single Bolt Top-to-Bottom clamp
Type B: Twin Bolt (Frt/Rear) Top-to-Bottom clamp
Type C: Twin Bolt (Right/Left) Top-to-Bottom clamp
Type D: Side-to-Side clamp (single bolt)
Type E: Hinged Rotational Clamp

Type A, B & C are typically COMPATIBLE with 7x9mm saddle rails.
Type D & E are typically NOT compatible with 7x9mm saddle rails

However:

For type A, B & C, we do recommend you to test or get confirmation from the seatpost manufacturer that the length of the standard bolt(s) gives sufficient thread engagement when used with 7x9mm rail and that the seatpost still passes all required test/regulations. If it is not the case, longer bolts may need to be used.

For type D & E, seeing the increase usage of oversized rails in the saddle market in general (either to adapt to new materials such as carbon, or to give additional impact and/or fatigue resistance for specific usage: DH, Freeride, Heavy Weight rider…) manufacturers of this type of seatpost have started to offer optional clamps to fit those different dimensions. Please inquire with your selected seatpost supplier to know if they do offer this option.

Hoping to have informed you sufficiently to help with your seatpost selection, at your disposal we remain for any additional information you may need."

thanks for the info... but i'm trying to switch from oval rails to round rails... and that's where i'm running into problems. i think i will email USE and see what they say.

2ndGen

You shouldn't have any issues with using that Alien post with round rails then.
Guess you'll just have to get another saddle. Good luck.

ravenmore

I posted this earlier, but this is what I got when I cut my KCNC down:

NathanC

About to cut mine down. Should be about the same weight.

M_FactorX19

got my 3T doric team post and 3T arx team stem in today. sorry no weights or pics but ill try to do that tomorrow. i also picked up a few parts today while at the local bike shop buying a floor pump and some CO2 cartridges. first being a Rival FD to go with the rest of the group parts and second a new carbon cage. i also just placed an order online for a Force BB30 crankset so that should be here soon as well.

plans for the near future are bars, kcnc skewers, kcnc or the like seatpost collar, and maybe some kcnc ceramic pulleys. after that im DONE with the Fuji!!!! i just plan to race the crap out of the bike now that the season started and will be on the look out for a new frameset later down the road to move most of the parts over too. im not sure what the final weight will end up being but i doubt i will hit the 15 mark without a new fork or some light wheels. i should however be in the low 16s or high-mid 15s though so not to bad for a bike that started out weighing 20lbs.

again sorry for the lack or pics and weights but i went in to work at 5am and didnt get home till 6ish so im beat.
