Hereby the list so far:
As much as possible i have used real weights, note that frame is slightly heavier, this due to a bigger size and it now includes all parts attached to the frame.- Frame:
906 Grams (included rear and front hanger + and seatpost clamp)
Finish: Raw Carbon (might be going for glossy for 30Gram added weight if possible)- Fork:
Finish: Raw Carbon (Might be going for glossy for 17Gram added weight if possible)- Fork Shortened
about -20 Grams weightsaving- Seatpost "Brand X"
127 Gram (Gloss, raw carbon not an option)- Saddle
90 Grams Carbon (ebay)- Stem "Ritchey WCS260 with titanium bolts"
97 Gramshttp://fairwheelbikes.com/c/forums/topi ... -review-3/
Please note that the stem scores average in deflection, and better than the lightest option available, Also note that this is the only lightweight stem wich does not use titanium bolts, with titanium bolts this is the second lightest stem available and it will also climb in the stiffness to weight ratio. Given the low price, i can't think of a better choice.- Handlebar "Brand X"
Already in stock, I will contact the manufacturer for a raw carbon version, except for the sandpaper coating it has on the places were the stem and shifters attach, don't see the use of protective painting if there is already bar tape. So maybe 5 grams extra to save here.- Bar Tape "Deda?"
Might not be deda, one of the lighter bar tapes, but has to provide some comfort and grip.- Headset "1 1/2 - 1 1/8 integr.???"
I can't find any headset weight comparisson. Any suggestions are welcome. With the frame they will supply a headset, this one is 78 Grams, i think there should be some weightsavings possible here.- Top Cap "Torontocycles"
5 Grams including bolts- Spacers "Point One Racing Nano Torontocycles"
2.2 Grams 2x5mm- Expander "Extralite UltraStar 2 Expander"
I might be going for the slightly heavier Mcfk expander, it can't see how this one will grip.http://www.starbike.com/en/extralite-ultrastar-2-expander/http://www.starbike.com/en/mcfk-expander/- Crankset "Cannondale Sisl2"
Necessary to reach the 5Kg, stunningly beautifull as this part is expensive, compared to the weightsaving it is worth it.- Bottom Bracket "BB30 cannondale included"
COuldnt find actual weight, but all BB30 cranks seem to be around this weight, if it is heavier ill just buy one wich is 57 grams.- Shifters "Sram Red"
Not as good or beautifull as my beloved campagnolo, but nothing can compare to campa. but its cheaper and lighter. So for this build the right choice- Front Derailleur "Sram red"
76 Grams- Rear Derailleur "Sram Red"
143 Grams- Shifter Cables "Power Cordz Swift or alternative
Saving weight on the cables is necessary as each gram counts, Any experience is welcome, so far i just picked one of the lightest out there.- Chain "KMC 11SL"
230 Grams (110 links)
Already using this chain, As i see the chain as a consumable part, it can't be too expensive- Brakes "Mr. Control / Planet X with titanium brakpad bolt upgrade"
Already using those brake's and i am really happy with them.- Brakepads "Swiss stop black prince"
0 Grams (brakes are weight including pads, i assume pads will weight about the same)
Seems to be the best out there, and i am using them already on my TT and Race bike, Don't Change a winning team.- Brake Cables "Power Cordz swift"
I have to admit, it is kinda scary to give up my reliable steel braking cables, it is a thing im not completely sure about. Any testing of these cables would be fine, if i think steel is safer, ill use a set with steel or titanium inner cables and ill have to shave off the grams somewhere else.- Rim front "Aero 20height*23mmwidth tubular, raw carbon"
235 Gram's- Spokes front "Sapim CX-superspoke"
76 Grams (3,8Gram each 20pcs)
Hope they make a stiff enough wheel, if not ill replace them with CX-Ray's- Nipples "Sapim, included with spokes"
6.4 Grams- Hub front "Bitex Rar 9 Ceramic bearings"
As the small bearings worry me a little bit. Ceramic shold be more dureable and reviews seems fine. I have spoked 1 Wheel with those bearings before and i haven't heared complaints from the customer.- Quick Release front "Titanium"
Not as easy to use and fast to switch as conventional steel ones, i will probably replace those while racing. I already have them in stock.- Rim rear "Aero 20height*23mmwidth tubular, raw carbon"
Maybe 38 would be a better choice for racing, but i already have a set of 38 tubes, and as this is a lightweight build.- Spokes Rear "Sapim CX-Super & CX-Ray"
100,8 Grams (3.8 / 4.6 Gram/pcs)
Stronger spokes were needed. I've seen this theory of using different spokes for drive and none drive side, and i am looking forward to test this.- Nipples Rear "Sapim"
7,68 Grams- Hub Rear "Bitex Raf 10 ceramic"
192 Grams- Quick Release rear "Titanium"
23 Grams- Tyre "Tufo Elite jet"
312 Grams (2x156 Grams)
As i prefer 23mm wide tire, this one is claimed 20 but measured 21, this option is much lighter, If ill be able to shave some extra weight of by tuning parts, ill replace these for heavier more puncture resistance s3 tires from Tufo.- Glue tubular
25 Grams- Cassette "Sram Red 11-25"
The lightest out there without compromising performance, Titanium isnt any lighter, and aluminum cassettes wich are lighter are way less dureable.- Pedals "Speedplay zero with Ti bolts & spindle's"
155 Grams (probably lighter because ill replace also bolts)viewtopic.php?f=3&t=68720- Bottle Cage's "Brand X"
Pictures will follow soon, i know i can get a few grams lighter, but these one keep bidons tight over the cobbles, already using them.- Numberplate Holder "Brand X"
Carbon numberplate holder, might replace clamp bolt for titanium, just for the extra gram i can save.
TOTAL WEIGHT: 5041Grams
I am not there yet, but i am close, i have used realistic weights, and didn't seem to forget any parts.
Now the second part of weightsaving, The tuning.
First ill replace, were possible Steel for titanium bolts.
Think ill buy a whole bunch at torontocycles,
Also for savings like derailleur wheels, and replacement parts of titanium. I have no experience with this.
I hope 160 Grams of extra weight savings are possible. might be a little optimistic.
Feel free to shoot at the configuration made above, and any tips for replacement parts are welcome
