New Langster frame vs pro frame

Does anyone know how is this pro one different to the one on the new Langster?

As both are apparently:

Specialized A1 Premium Aluminium, Track Geometry, fully-manipulated tubing, compact design, integrated headset, bla bla.

I can see the "pro" one is a different "aero" tube shape, does this actually help at all? Just curious really.

Pro has stiffer tubing, fork is not drilled for a brake, has the aero venge seatpost, has ~10mm shorter seatstays and therefore slightly snappier handling.

dat downtube

Cheers @hazzelfrazzel.

"fork is not drilled" - nice one, guess my build will be cheaper :).

Wanted to get the Langster but will instead get this frame and whatever else I might need (erm, wheels, chain/chainset, calipers/brake lever - do they come with cables or are they separate?, free wheel cog, saddle.., bullhorn)

But is the frame drilled at the back for the calipers?

Langster possibly will be, pro will not be. It's a track bike as where the langster is more of a track style urban bike.

Basically you're not going to be able to use any brakes on the pro frame

Would drilling the frame cause any issues? Is it straight forward?

I like the frame much more, as @Jezston noticed :).

From a quick look.

Langster is a street legal track bike (can run dual brakes)
Langster Pro is a Track only bike (not designed to run brakes)

Bit like a Dolan FXE which is a street bike based on a track design, can take brakes and longer chainstays, or the Dolan Pre Cursa which is more track and dosen't take a brake and fork may need drilling.

You can get clamp on brakes for forks and adapt to fit the rear on non drilled framesets, depends on if you want the hassle and what you intend to do with the bike.

Other answers in :)

Drilling the frame/fork voids warranty for a start :)

Fork can be drilled as it has an aluminium crown but you'd need to have it done with a pillar drill or something to get it perfect.
The rear can't and you'll damage the frame in trying, I'd seriously just get the langster or look at Fuji, the 1.0 and 1.1 are aero track frames that can take brakes. You might find them cheaper used

With brakes and drilled.

Thanks everyone for clarifications.

Like the frame so much, I think I'll cope with only having a front brake eventually.

I am not a hardened bike rider, just need it for my 3-4 miles daily commute, possibly more in the future.

I've seen a few images on Google and they (some) have front brakes.

Or this approach on the back calipers, without drilling the frame!

Yeah, you can also just get a replacement drilled fork if you want to go for the Langster Pro and ride it on the street. That way you've still got the undrilled track fork when you come to sell the frame on in the future

Oh yes, good advice!

I wasn't being positive :(

I think that downtube looks weird.

Does anyone know if the fork accepts a wheel with a disk brake?

I am thinking of this front wheel, assuming this would fit, but if it doesn't, how would I know whether this is narrow enough to fit? Kept reading the description but I don't understand.

Not necessary, especially if it's done from the shop who sell them.

I think you need to do a ton of research and work out what you want from the bike, as you will need a new fork to run a disc brake wheel as the frameset you have your heart set on is a "Track Bike" for velodrome racing. Track bikes don't run brakes.
You can make it happen but you might as well buy something designed to run a disc brake in the first place, probs cheaper, safer, less hassle. Unless your after the challenge :)

The wheel your looking at will fit the fork, but it only takes a center lock disc and can not be used with rim brakes.

Wasn't aware of that one Ed, just went with modifying things is a void generally.

It does all seem a lot of work, more worthy of a project thread :)

I know, you're right, I've done fuck all today at work but reading about bikes/frames and what do I need for a custom build, how is that called, etc, etc.

I was convinced to buy the new Langster but I like this frame so much, I am now keen to get parts and assemble it myself. Never done this but with proper research and a ton of videos, I should be able to do it.

Thanks a lot everyone for your help so far, I really really appreciate it. I got past the stage where I Google 'chainset bike' or 'bike frame which one is the downtube' lol (not a native English speaker as you probably noticed already).

worthy of a project thread

Really up for a challenge, maybe a mod could move this eventually. Will try to squeeze as much info as possible I can from you guys.

Cool.
Cost it out before buying the frameset, you might find something killer used for way less.
