Over the past couple of days, I’ve been pondering what to do about my premium bike. I’d like to build up a mid 4-kilogram weight weenie. These bikes are somewhat different than the ones that I had previously in my dream stable of road bikes.
While I like the new Guru Photon, I find it quite expensive. At $4,900 USD for the frameset alone, it’s almost in the same price league as the Colnago EPS and Pinarello Dogma. Unless I can source the frame by becoming a reseller for Guru, I can’t really rationalize spending that much money on a frame alone, even if it is sub-800-grams. Still, the Photon beckons me. The lifetime warranty on the frame isn’t bad either.
There’s also the Storck Fascenario 0.7, although this bike is even more expensive, $6,300 just for the frame, fork and headset.
Don’t get me wrong, the Colnago and the Dogma are great bikes. One is lugged, one is a monocoque, so they are different. However, I’d like something more exclusive, rarer, that isn’t recognized that easily and that is more personalized. Guru offer custom geometry and fitting, no extra costs. The Photon comes with an ISP or without, and is available in a BB30 version.
An interesting alternative might be the Scott Addict R1 frame. It retails for about $2,000 USD less than the Photon, but it lacks BB30, which would be a requirement on this build. The Addict leaves me a bit lukewarm to be honest.
Whatever the weight of the frame is, it has to be around 800gr. For wheels, I’d go with custom-made Edge 1.25 with Extralite SX hubs. Total weight, about 780gr. The gruppo would have to be SRAM Red. While this is supposed to be a a weight weenie, I’ll try sourcing some AX Lightness parts, but they are incredibly expensive. Their 55-gram saddle costs about $650 USD. All of their parts are extremely light and extremely expensive. While I believe in saving weight on this future build, I won’t have an unlimited budget. Still a saddle, stem, seatpost combo from AX lightness would weigh around 199 grams at the most, but cost close to $3,000 USD. Looks like I found some parts cheaper than expected. AX Lightness parts are starting to look quite appealing. Also, for this build, I don’t mind getting second-hand parts to keep the costs down.
That being said, I’m sure that I can find less expensive and almost as light parts elsewhere. For example, the 74-gram AX Apollo saddle would cost about $400 USD. The new Tune Concorde RR 08 weighs 54 grams and costs $240. The Ax Daedalus seatpost is only between 95-135 grams and costs about $500 USD. If I take the Photon, it will be with an ISP, so all I’ll need is a lightweight clamp.
The AX Zeus stem weighs an astounding 64grams and costs about $860 USD. A Synatce F109 weighs about 100 grams and costs $120 USD. This is an example of where cooler heads should prevails. Sure the AX is lighter, but at 7 times the cost. That’s a lot!
As for brakes, I’ve listed the AX Lightness Orion, but I might be able to find cheaper M5s that weigh just 30 grams more but cost half as much.The Orions are extremely light, but they don’t really brake much. Seems kind of an oxymoron: why would have brakes that don’t brake? Just for show? In fact, the more I think about it, the less I am interested in spending so much money on brakes. I’ll probably just source it through a supplier for some TRPs, Zero Gravity Gravitas (120g ~$875), or Zero Gravity Negative G GSL (140g ~$400). That being said, since the KCNCs are made in Taiwan, I’ll probably be able to find them for very cheap. So basically, it’s 20g more for the KCNCs, but a quarter of the cost, maybe less.
My goal for this build is to assemble a lightweight bike, at around 4kg, that can still be ridden. I don’t want a show bike that will break as soon as you put the pedal to the metal. I want something solid that will last for a while.
So, for now, the components look as such:
Guru Photon size M-55cm 747g $4,900
Edge 1.0 fork 295g ($710) This fork comes with the Photon frameset
(AX Lightness Daedalus seatpost 86g $468) Since this will be an ISP, no need for a seatpost
Tune Concorde RR 08 saddle 54g $240
Extralite UL3 stem 78g $210
{Velocite LICOS 176g ($229) I have one ready to go}
AX Lightness AX 4000 handlebar 110g $600
Edge 1.25 + Extralite SX hubs 780g $2,300
{THM Carbones Clavicula crank 410g $967}
Storck Powerarm SL BB30 440g $938
Fibre-Lyte chain rings
AX Lightness Orion brakes 95g $1,000
KCNC CB1 w pads (115g) 164g $250
Tufo tires 320g $156
SRAM Red FD, RD, chain, shifters 760g $700
SRAM Red cassette 155g
Soul Kozak Top Cap 4g
FD clamp 10g
Soul Kozak Seat Clamp 10g
KCNC Skewers 46g
Bar Tape
Cables
