I'm figuring how to cut weight without loosing my ti-frame...Ultra chain -20g,TA Horun rings -g?,new rear brake,new TIME carbon pedals -40g,Ultimate seatpost -40g...150g possible?

Scott frame would cut 600g but new frame and Look fork are bit pricey...and ti takes race abuse better. Think about 30 race trips/summer with full loaded race cars....frames look bad easylly but not ti.

Think there are little erros in list,cable weights etc. I have be more precise next time. Parts were late and road was hot....

I weight 85kg/185cm so parts need to hold on hobby racing...

So what to cut?

Why not using Speedplay pedals? I'm going to use them for next season.
they are very light and solids.

Zero Gravity brakes will save you over 100g.

-Lightest Speed plays have weight limit? And I have 2X Time Impact Ti Mag's and one pair Impact S's with ti axles in my road/TT/cross bikes. Okay, I could change one pair for Speed play since I have 2 pair of TIME shoes,they take S-P cleats and two pair Northwave's for Time's. But new times are ~200g...old are 241g.
-cutting EA bar...it's VERY thin there. It would save only few grams, max 5g.

I'm getting Tune road q-releases,4g lost. :D Old ones goes to TT bike.

And I have large quantity alloy cassette order going on but minium order is 20 pieces...11-23 10s. would be 95g. So there is ~-100g!

Ultra chain in must now. I have ridden previus for whole summer....danm,no wear...Change that to be sure and less wéight.

I have 100% CF seat post,100% CF/kevlar seat,CF seat clamp and CF brake projects going on but It seems that I have new job now...as mecanical designer. Learning those new materials and stuff will cut my time much. Stainless steel is more new than CF for me. :P

Samu,
Just curious; you say you race, so why do you have a sub 6.8kg bike?

Being WW?

:D

There is nobody ever to weight it anyway...just too see racer frieds faces when they try it....2kg less than moust.... :twisted:

They weighted bikes only on mt etappes on Tour de France. And I wasn't invited there some way? :wink: Hey, I'm not a pro!

This is just old hobby, have to have light but usefull bike.

If I wouldn't race, I would get those light brakes and CF frame,Smolke bars etc. Craching with those is not what I have in my mind. EA bar is cheap and strong. So is my own desing frame. Some day I quit or get somethin cheap race bike and build something seriusly light.

Like:

Frame -600g,bar 50g,brakes -100g, cassette -100g,pedals -40g,chain -40g,seatpost -40g=970g...~5.7g for 61cm bike without any gimmicks. No 100g tubulars,plastique cables etc.

I had Trek OCLV for two seasons but it was sooo flexy! Light that was...

I try to loose weight now from me so I could use lighter parts...but getting more power is opposite direction...

Samu, i'd say you built yourself a nice bike there:

- it is very, very light
- i see no part i wouldn't trust using in a race or for everyday use, even for someone your weight
- it also looks gorgeous

bottom line: leave it as it is! Don't fiddle with the brakes if you do races that include longer downhill sectios or if you ride criteria, its not worth the few grams. Same thing with the pedals: if you are happy with them, keep them!

regards,
Martin

I agree. for your weight, your bike is already very light. an alu cassette would wear out very fast. the Speedplay X1s have a weight limit of 185lbs, as I remember.

What about shoes? Rocket7 shoes could save 200g.

Thanks, Martin!

I have been thinking where is limit for weight/safe/stiffness on all parts and so those what I have found to be good. Stork fork is excelent, so is King, and Record bb is holding fine ,Ea bar feels safe etc.

But when I see here those 3.8kg etc bikes, my bike begins to feel heavy. :roll:

Thanks keeping me at sea level!

A sweet bike in every way: trustworthy and ridable parts and great looks. Leave it as it is!

Just one question: aren't 100 g for Campa cables a bit optimistic? ;)

Oh, and I'd use a black seatpost and a black stem but that's just my taste. Great bike, 2 thumbs up! :D

Getting lighter....

I bought C10 Ultra chain. 265g. 248g for my bike (=-4 link pairs). -10g from -C10.

I also got NEW Tune full ti cassette 11-23 with white ceramic shims. 141.61g. Looks nice, ramps etc. +Tune alloy lockring 3g. Record 12-23 was 185g. So -43g.

Total -53g.

I'm also making order to Starbike for Tune road q-releases (-4g). Those boys are fine supply for hart to get WW-parts! :D I proud long term curtomer of them. Most of my bike parts comes from them.

Then I have to finelize my CF- seat post and seat projects. Seat post tube is in cryofit progress now. Then I have no idea to cut more in limits of realityes...

LW Obermayer. We claim them "max. 1.050 grams". But all sets that came out so far are 992 - 1.001 grams.

You could save about 150 grams (most of it rotating mass).

Not the cheapest way to save weight though :)
