Fixed Time Trial Bikes

Was more in reference to his conviction and restraining order for stalking a woman, but yeah roller hour records are a bit weird too. Anyway, we digress.

Selling a clincher disc if anyone's interested http://www.lfgss.com/conversations/274512/

if he's doing a rollers hour record why use discs? wouldn't be better to use some lighter wheels?

As @umop3pisdn says, spoke drag is nearly all of the aerodynamic drag on rollers, hence the 48 spoke wheels on my RollerFort, which really do provide a lot of extra resistance compared with 36 spokes. I've used the front Hed 3 on the rollers too, and that's ridiculously easy to spin compared with even the 36 spoke wheels.

Lighter wheel on the rollers would be pointless, even if they weighed nothing you'd still only cut rolling resistance by a couple of percent. Heavy wheels are much nicer, as riding on the rollers has very little inertia and every little helps to smooth out any choppiness in your pedalling. Smoother pedalling isn't really an end in itself, but in my experience more inertia does make roller riding more comfortable.

You have your powertap laced to an Archetype right? Wanna buy some wheelcovers for it cheap?

Still haven't build that up yet, will go to a Kinlin rim which should be wide enough.
PM how much you'd like for it.

Enter your text here...it does indeed have guides for rear brake.....

3cm rule?

Got this built up a bit late in the season but gonna try squeeze in some sort of training on it before winter really hits

Nice

^ Saddle setup for chug nut removal in the tuck? Or just picturez? 😀

Find it hard to stay on it otherwise. All the other examples of this saddle been used have been in a similar position?

Lovely bush: beautifully understated and clean!

The wood/champagne combo is spot-on and the orange wrap a master-class in detailing: less is moar and contrast > matchy-matchy evrytim.

Full rep for savvy cabling too!

Haven't you got any untrimmed bars? Would be nice to level them, but obviously it's not practical with a road lever on those ones.

I usually find at the end of a straight I'm right on the tip of my saddle in the tuck. I have a turbo on my pub biek and find it a bit tuff even in the seat. Whatever works. 😀

Right time of day n all.

Hehe! I appreciate your kind words :-) The cable squeezes in between the tri bar and arm rest clamps, had me sweating/shouting yesterday trying to get it to look clean but functional.
Bar wise I got a couple ITM Citta's untrimmed but they black and a bit hhsb tbh, but as you say its not that practical with the cough sugino 75 carbon cough lever ;-)

@Ordinata - Taking it to the velopark today for a proper session, so will have a bit of a play if anything starts hurting too much ;-)

Think this has already featured

Very nice.

What model are the base-bar, extensions and pads? Something Mavic?

Must.resist.

^^^^ some bike!

I wasn't for saying in the guys for sale thread n shitting on his parade but I'm pretty sure the bb on those is waaaay too low to be track compatible.

A guy once brought one of them to the track in Glasgow, I think he had 170mm cranks and was almost hitting the track with his pedals, in the straights.

I'm pretty sure the bb on those is waaaay too low to be track compatible.

I imagine the stock BB drop is 60mm, like their TT frames, but they had an optional set of track ends and a tall crown race to lift the bike a bit higher, see http://www.timetriallingforum.co.uk/index.php?showtopic=76343

Probably too late to get a set now as the Velocity was on my shopping list two bikes ago :-)

Ah ok.

Did wonder if there'd be something of an oversight on the designer's behalf but makes sense now. Kind of.

something of an oversight on the designer's behalf

Not so much an oversight as Isaac being cheapskates and re-using the Joule TT bike as a "track" bike with just a swap from dropouts to track ends, instead of making a new mould with the right BB drop for a track bike. Adding 10mm to the fork length to make it high enough is an appalling bodge.

On the other hand, I think the T3 has the same 60mm BB drop as the P3, and has been successfully used on the track not just for pursuits but for points/scratch/madison, all of which involve slow-ish riding around the top of the track

T4 has 60mm drop, P2C has 60mm drop and I ride both at Newport with 175mm cranks with no issues.

We've had one rider on a big new style P3 clip a pedal once (75mm drop), out of 100s of hours aero testing but apart from that nothing and we've had every bike you can think of!
