Off piste you mean!

Ba-dum-tish

After you guys kindly pointed me in the direction of the correct thread and also gave me some feedback on the setup, I've now been for a ride and refined it a little:

I've changed the stem and moved the seat forward. I've also adjusted the angle and position of the brake levers. I had it set too long for me. It's definitely an improvement, although I'm sure there's more I could do. I realise the frame is a little small for me, but if I can get a comfortable set up then I'll try it for a bit.

Once again thanks for the feedback.

Nice on bro, looks like you've got a tidy little setup there. Did you get it all built up on Sunday? Maybe it's just the angle oh the photo, but I don't think the frame looks as small now that it's built up.

Off piste you mean!

No, I wish!
Too hard, not enough fresh snow.
Had to take care of wife and kids, too!
Besides that, not enough exercise. Last time was 7 years ago.

In short, your badly interlaced wheels will probably last much longer than you need them to, making them doubly annoying to engineers, because things should be right, and wrong things should fail to prove the point.

Things should be right,and crucially safe, but the improvements in hub, spoke and rim materials seem to be allowing many previously discouraged spoke patterns to appear in high end wheels, blurring right and wrong. Drive side radials and crowsfeet can now be bought at huge cost, to make you go faster and appear more attractive to the opposite sex. Meanwhile Stevo and Smallfurry can have fun learning.

Fewer, better spokes;

Depends on the caliper, how close you have them to the rim to start with and especially the rim width. Short Tektros are a squeak with 25c tyres on 20mm rims - you have to bang the tyre through - so the limit seems to be about rim width + 5mm. A 28c on a 23mm rim should be OK.

Thanks for that MDCC, I started realising, after posting that stuff, that the rim width (and therefore where you set up your calipers' reach) is the crucial detail here. Cheers.

hah! ... blah blah ...as for the choice between lug and fillet brazed, have you though about having both? ...

You (edscoble, or Harry - although I'm fairly certain I know Harry wouldn't even consider it) would have some trouble finding a framebuilder who would be prepared to build a bike with bi-laminate joins these days. It was an affectation of 50s stuff to try to create something 'different' and is generally thought to have little or no beneficial effect - maybe, perhaps, some extra stiffness created by adding the layer of 'lug' on one side of the join. It's like an external butting, basically. It was a technique developed by Claud Butler that allowed some element of uniqueness when there were tons of amazing frames being built by all sorts of people, in order to make his top end builds stand out, and it cost a lot extra to have it done. But it isn't a combination of lug and fillet brazing. The joins were fillet brazed, and then the 'lug' effect wass a layer of handcut plate wrapped over one side of the join, and it's a very very laborious process. Almost no one, except those dorks who build funny super expensive rando bikes for the NAHMBC, builds them these days.

Just sayin'.

Nice to learn something news, thanks mate, although I assumed it's less laborious when you have a combination of lug and fillet braze (as in lug on some places, fillet brazed on other), not as the one you describe it.

Yep, Skully, I think Ed meant having lugs at the headtube and brazing at the seatube/toptube, for example.

aha, sorry my bad, I thought you meant bilaminate, you just mean, say, fillet brazed seat cluster and lugged head tube, or something like that. I getcha.

Oh I was suggesting bilaminate as well as the mixture of fillet braze and lugs, just wasn't aware of the amount of work that is required for bilaminate construction.

One thing I like the most about the forum is being able to learn something new everyday.

still very purty though;

But it isn't a combination of lug and fillet brazing

What about Alex Singer frames? I naively thought they were "combinations"

I think this is bilaminated as well. It was at EHBS last year and i´ve been in love ever since.

^ Amazing. I'm guessing they were'nt at NAHBS. No need. People come to them. They won't even translate their webpage. The Chuck Norris of the bike world.

Harry your frame sounds really nice. How much is that costing you?

:d

They weren't at the NAHBS because he die.

hubbas hubbas hubbas;

I think the fork is a bit bent.

looks a bit big for you, ed.

Just a cm or 2

Not alarmingly big, I just put the saddle slightly lower than it should be as it's more comfortable for me even though it's not the most optimised position.

also, I need a less aggressive saddle to bar drop, the Holdsworth fit the bill.

very nice, like what you've done with the cranks.

It "looks" a tiny bit big, but then again i'm sure its set up so it fits correctly.

The fork does look a little bent, you can fix that though.

... made me think I'd got it wrong. I know what you're like ed, don't I?!

@ Loic
Yes: Bilaminate joins look like a combintaion of a lug and fillet brazing: I was really just trying to say to ed that the proper term is bilaminate, and that although it looks like a 'lug' on one side, in fact that layer is over the top of fillet brazing, which have to be hand cut, and brazed on wrapped over one side of the join: so they're not 'lugs' in the sense that you can't buy them pre-cast. Basically this is only semantics: and yes they do look lovely. I think a lot of more down to earth frame builders wouldn't want to do it, and no doubt probably think you're a poser... I know that the NAHBS lot are into all that... maybe someone like Mather or demon would be more receptive to esoteric resquests like these. And it would cost you!

I'm so glad the headtube weren't bilaminate! have to replace it soon due to headset no longer fitting in the headtube (right now it got a shim).

picked up another master, was a bit rusty and the chrome on the lugs is gone:(
going to have it painted glossy black and build it up with the parts that are now on the Pinarello. So it will be only black and silver.
