"SONIC boom" (aka Yokel-Motion 2.0)

In other news...

I bagged a 55t Fibrelyte off of TTF, which is nice but I've been putting off assessing what this will do to my short crank ambitions.

I also learned that having the grips of the base bars level with the top tube, is meant to be beneficial in yaw conditions. Maybe it does, may be it doesn't; but it does provide a convenient excuse not to trim my steerer (the Ventus stem has a lower stack than the Zipp I was using).

Sexy - I want a skinny steel frame to replace my Precursa.

Is that ring 144 or 130BCD?

130mm: I've committed to 7400 cranks.

Although I've been offered some cheap Campag Pista. But they're 170mm and 144BCD.

PS Did you get any clips?

Rad. Those bars are the dogs danglies

vulture.jpg - Let me know if you no longer have a use for them.

Yep, got the Vuka clips - Thanks for the tip off! PJ originally sent the wrong ones, but came through in the end :)

Will see if I can reduce the scoble-risers. The pads look sooo comfy - And I found my current Deda's quite comfy anyway.

Also wanna try some J-bend extensions. <£20 Anyone?

Me too: get your own thread.

I'm not too sure about that tbh

The grip/TT/yaw thang?

It was just a passing comment from Nutshell, which I'm using as an excuse for my laziness.

This build looks rowdy, proper HHSTTB apart from the green tyre :-P

On another note, Ive been tempted to get one of them carbon rings for a while, how solid do they feel?

rowdy

My work here is done!

I've not used the ring yet, but there are plenty in circulation and have been for some years: I've yet to hear of any problems.

PS Open Pave are the tyre of choice for early season ballers. ;)

I completely agree... cc @umop3pisdn

p.s. bike looks awesome, love the massive crabon front end on skinny steel

Cheers, I'm started with the front-end and am working back.

The rear wheel is shared with my road bike, which is the real reason I'm riding an OP: lazy.

Awesome project!

Front end done!

The "middle" is a WIP: I haven't achieved gooch-nirvana with the Tritone, so I'm hoping to try an Aerocoach saddle if they haven't sold out by Friday (can you put in a word for me @umop3pisdn ) and I'll continue experimenting with short cranks (on the look out for more FC-740x to chop).

The back end is where I'm a bit stuck, ie the rear wheel.

I bagged some cheap Pacenti TL28 in the Planet X sale and got a BDW hub, intending to use it with a RALTech. But RT are out of action for the rest of the year and a "naked", 36h, shallow rim doesn't seem like it should be my first choice.

A "proper" disc is out of the question due to my 46mm chainline.

I've been using the Archetype-rimmed wheel off of my road bike, but I'm moving to Reading for three months and that will stay here (lending the road bike out).

Ideally I'd like a wide rim and am not desperately fussed about it being super-aero as long as it's no worse than a 32h, bladed spoke, Archetype pending RT getting up and running again.

Having said that, I've got regular work ATM so if there's an option on a par (both with regards to price and performance) with a RT skinned, 28mm rim then I could consider that too.

Time is an issue too: not only are we half way through the year already, but it would be much easier to have this sorted-out before I move, so a fortnight or so...

Might be a fair bit of effort but you could pick up a rear trispoke and convert it to fixed with a surly fixxer? Would also give you an oppurtunity to play with the chainline. The usual issues of de-bonding it or unthreading it might not apply if youre only doing to use it for TTing (and not skidding I assume)

Good call (aside from it being "skinny"): the road version of the SPNK "fixxer" is 46mm: double 'spokes is never wrong!

And no, I don't skid.

One of the olf Pro discs with SPNK adaptor?

Only a small number of early Hed3 wheels work with a Fixxer. Specialized don't, nor do later Heds with their own design cassette rotor. Pro clincher disc with the FH-6600 or FH-6700 based hub works. At some point I'm going to hassle Walker Brothers
about their Wideboy disc, they promised a track one for 2016 but there's no sign of it, and I really want bolt on sprockets anyway

Can't find these, only Prima.

Why do you suggest them over another disc + adaptor?

They fit the bill (aside from the UKIP finish).

I know bolt-on > screw-on, but why the insistence now? Because if you're spending that sort of money, it needs to be "right"?

Because if you're spending that sort of money, it needs to be "right"?

Exactly. I already have a Pro with a Fixxer, wide would be nice but wide and bolt on would be perfect, especially if I want to use it on the tandem too.

The front spok on my CAAD is a Specialized (I think) and it has threads that look like theyd fit a cog, assuming because it was converted from a rear. Surely this means a fixxer would work?

Do you even Fixxer? The conversion replaces the freehub rotor on common Shimano rear hubs, using the large hollow central bolt for attachment and the splines on the hubshell for drive.

A Specialized/Hed with just 1.37"x24 threads on the hub is for a screw-on multiple freewheel. You can get adapters to move the chainline to suit fixed use, but the adapter unscrews off the hub when you try to brake, so it's still a suicide hub even though the adapter has lockring threads.

My bad. I was thinking of one of these:

...which would still work for Scilly as he wont be braking with his drivetrain

Is there an easy way to tell if a rear HED can take a fixxer?
