London Fixed-gear and Single-speed

I'd been mentioning this enough so I thought I should make a thread for it so I can update with progress.
This is not gonna be a super light build because I'm on a bit of a budget.
Parts so far:

FSA OS-99 stem
Deda Big Piega drops
DSP lizard skins tape

Selle Kuota stripped saddle
Condor Carbon seatpost

Sram omnium cranks with DA 51t chainring
Shimano R540 SPD-SL

Dolan seta 58cm frame and Dolan road for, for the time being until I can sort out a straight blade.

This thread will be updated with pics soon.


My target for this build is 7kg so nothing too hard.

Cockpit

bar tape anti porn >>>>>>>>

;)

Shave your arms dude. More aero then.

You'd be surprised at how aero my arms are :)
I could shave my head and save a few grams.

What wheelset are you going for, and what is your overall budget for the build?

I am not 100% decided on wheels, I will probably go with a cheap Halo aerorage* track rear and road road front, weight of that is 1.7kg and I'll convert the front axel to bolt on.
I would eventually like to either move to a chinese carbon wheelset or american classic 420.
With braking surfaces rattle canned black of course.

Is that a gorgeous baby blue bedroom in the top pic?

It's an incredibly messy baby blue bedroom!

Chainset

I changed my Omnium chainring bolts yesterday because they are made of cheese. When I got my new bolts yesterday I only had to remove three of the old Alu ones as the other two had dissolved somewhere in East London.

I kept them instead of the DA ones because they were 1/3 of the weight, may change over time if I get hold of some TI.

What did you replace them with Rob?

Steel chainring bolts FTW.

CRC had some Raceface ones for for £3.99. Had to use double bolts as I'm still using Omnom ring with the cranks, so they're quite wide.

Ok, this evening I got my Dammit on and did a bit of weighing.
CBA to post pics of everything on the scales but if there's enough demand I will.
BB-107g
Cranks-829g
seatpost and saddle-425g
Bars, tape and stem-488g
That's 1849g

Here's what I expect from the other parts that are yet to arrive/be bought.
Frame. forks and headset-1700g
Izumi supertoughness chain-330g
Shimano r540-330g
wheelset-1700g
Specialized turbo road lvs inner tubes x2-140g
Scwalbe ultremo x2-290g
6309g.....
That works out way too light, I must have forgotten something.

Pedals

Nope, shimano r540 at 330g

spacers, cog, lockring, rims tape.

a seat post clamp.

Think you're being optimistic using claimed weight for tyres and tubes unless you're going to do the proper weight weenie thing of ordering 50 and only keeping the lightest 2 or 3...!!

There we go, thanks Ed.

This is going to be about as good looking as CB's Seta

True but are we really looking at more than a 20g variation max?
I reckon it's safe enough to say this should be under 7kg still.

:0 don't ever say that again, he tried to go super light super safe and I'm looking more at keeping it relatively light and looking decent.

Even with cheap part on my Precursa I still managed to get it to 8.5kg, so it doesn't take a lots to reduced the weight.

Especially when the Precursa is a very heavy alu frame (1800g, similar to a high quality steel frame).

Your crankset's very heavy, about the same as my Lasco one.

bits are nice, but choose another frame please!
(you can treat this as a challenge)

Omniums are never light and 170mm doesn't help either.
I know I could knock tons off by going 3/32 and a smaller chainring/cog combo.
If I had more cash to throw at it I'm certain I could get it under 6kg and maybe I will when it's built and I've got some cash again.

Come on Martin, it'll be decent but if you feel like buying me a pista concept to throw the parts on I'll be happy :)
Btw my preference is the 2007

Light and not bad looking

What's the weight on that one?

I hear there is a rad triple triangle for sells in xl somewhere around

Might have some Dura Ace 9000 pedals going by the time you get your frame and other bits and pieces. Obviously there are lighter options out there, but weighing in at 239g for "wide platform pedals" isn't bad. You can't fault them in terms of performance, and they aren't bad looking either.

What sort of timeframe are you looking at, seems Seta builds somehow tends to take longer than most other builds?

Dat colour :O
Well I'll be away for around a week, then be taking delivery of the frame.
Then a week or two to gather wheels, chain and other bits.
I'd defo be interested in DA 9000 pedals if the price is right :)

Why no MTB pedals? ironic given your fear of unclipping.

It's a combination of bad experiences with ATACs and the want to try something new.

Let's be honest, SPD-SL is the only way to go.

*MTB=Toy

I did look into Keos and had a look at them in the shop today and they're around 100g lighter than r540s but they felt so much more flimsy.

They're looser, which is idea for first timer.

I don't fancy walking in road cleat, and see no evidence that it's better.

oddly enough, the Shimano PD-A520 is lighter and cheaper at 318g.

Or the A600 which weight a very modest 286g.

Yes, I'd have no problem with trying them on a road bike.
The power transfer is supposed to be better with road set up than MTB and what better way to find out that to try it yourself.
If I have problems I can always change.
I should probably add that this isn't going to be an every day bike and will be used mostly for longer road/country rides and then track when the season comes around.

"Suppose" to be.

Biggest difference is shoes rather.

Yes it is and that's what I'm running on the MTB for the most part.
It is lighter than the m540 but heavier than the DA 9000.
Another thing to consider would be shoe weight though, most MTB shoes will be heavier than most road shoes.
Not that one is limited to MTB shoes, just need to find something like RO64s with the right cleat attachment for both.

Yeah exactly.

Have a good think about that, the biggest reason I went for spd is that it fit all purpose from everyday riding to long distance and sportif ride, meaning one shoes fit all.

Not an expert, but I would think pro roadies use "proper" road pedals for a reason. Just saying...

Yes, they're paid to ride them, and I somewhat doubt we're pro.

I agree they're far more versatile and definitely better when your off the bike.
I could just go for speedplay and piss on everyone...

They're fantastic, going against the direction of redesigning ski bind, however they're notorious for requiring slightly more attention due to the mechanism on the shoes rather than on the pedals.
