Dolan Pre Cursa / PreCursa / Track Champion

You read my mind. Just after I posted that I realised you couldn't get halos in less than 32h and archetypes in less than 28h. Was looking at a23s but cheaper hubs, like novatecs or something. That AC is nice, but pricey.

Ooh I looked at this a while back, you can get pretty light disc brake hubs that can be converted to use a bolt on cog.

@JB, what brake levers are those?

SRAM S500s.

With the £10 front hubs, the grand total will be £110 for a F&R which is pretty reasonable.

This too once you sort the chain line out.

Velo Solo do spacers so it shouldn't be too hard to get a decent chainline.

Depends what hub you use. Velosolos spacers are pretty much only good for loose ball hubs. Any kind of super light trials hub and you'd need a custom axle/spacers, not that it should be too difficult to get something made. My dad is making me something up for a sealed disc hub at the moment. Unfortunately due to budget constraints it's a bloody heavy one :(

it has 32c tyres.

Makes sense now. I'm using 23c

This is likely to be your lightest bike, why not get a really good lightweight wheelset to match it?

i.e. American Classic rear track hubs (24h) and front road hubs (Pro-Lite Como Front Hub 20h) laced to Velocity A23 would be very light in comparison to a typical fixed wheelset, maybe around 1200-1300g altogether compared to a typical 1800-2000g fixie skidder wheelset.

With heavy component on mine, it's end up 8.5kg, reckon with your, around 8kg or under.

By the way, think your saddle may need to be moved back a bit.

I use Miche Pistard WR Track wheelset Nic and light and have proved very strong on the road.

That's very nice dear.

Slightly slack chain but otherwise it's done.

Looks good JB!

I'm slightly jealous that you can fit the Stronglight 2000 to yours:( - I'm still looking for a used Miche to fit mine.

Tony

I didn't understand that. I was worried that they wouldn't fit mine due to what you said. Re you using the strong light 107mm bb? Cause that's what I am using and it is as tight as fook, but it fits fine.

Hi JB,

I actually have two Stronglight 107mm BBs which will not work as the crank spider hits the frame (making turning the crank impossible).

In fact there is no way the cranks would spin with a 42mm chainline due to the very bulky spider on the 2000's. I had to get a wide shimano BB so that it would clear the frame but this pushed the Q factor much wider putting the chainline well out of whack.

The root of the problem is that the Pre Cursa (my one anyway) has very wide chainstays with clearance for 35c Tyres which is an unusual feature for a track specific frame.

Must get back to finishing this build as it is presently unsuitable to ride with and I have yet only rode it briefly once on a test tun which was in late November as seen in the photo below.

Tony

That's strange. Is it a 54? There is literally 1 or 2mm clearance between the bolts on the spider and my stays. Yeah I am running 32s and its fine clearance wise, which is great.

This probably means nothing coming from me but I think your frame is a little small for you.
You've got long stem and a fair amount of seatpost.

You've got long stem and a fair amount of seatpost.

Quite common on track setups, but not on road bike setups.

But it can't be a track set up.

Awkward... Exhibit A.

front wheel still not finished yet.

I was referring to the QR btw.

JB that's irrelevant because Eingang is a really big guy and that was probably the largest fes he could get.
The PC I was talking about it small.

...

I know yo. It may be for the track though, just not AT a track. That is my point, innit.

@indra: exactly, you're right. and i'm riding it at the velodrome where those saddle to bar drops are more normal.

I noticed after seeing how similarly set up (size wise) our Setas are.
