For a Crit bike, I'd maybe raise the BB a tad and recommend a stiffer overall bike with less emphasis on comfort (ie: recommend Al or Sc over Steel or Ti), but that's about it. Actually, I would recommend steel but go for a beefy oversize tube selection and don't give a crap about weight.

A sweet steel frame and matching steel forks, and some killer aero wheels like Rolf prima Vigor SL's would make a real nice crit bike.

I have three kids, one of whom is into that expensive sport of cycling, ergo no money. I have to make do with what my limited budget allows. Given that I spend about $300 every 2 months just keeping the mongrels on the road I guess it was only natural to buy neanderthal. I got what I got. Measurements translated pretty well, so there's virtually no adaptation required apart from the differences in handling and gearing.

As for raising the BB, well I'm in two minds about it. There's nothing like the thrill of dropping blokes off your wheel by clipping at >60kmh. Scares the bejeesus outta them. A bit harsh on the pedal tho. :roflmao:

Thylacine 07-10-06 06:55 AM

Oh, I thought we were talking about your bikes.

Kids are a different proposition, of course. Make em work for it or get them on something cheap and bomber I guess. I hardly expect anyone in that position to pony up the 10-15k you'd need to sink into a specifically designed training/racing quiver.

But hey, what do I know about such things? I'm 34 and newly married but still think I'm 25, which comes as a shock when I attempt to keep up with 25 year olds! I can't fund my own cycling habit let alone someone elses.

Mavic hubs need a spacer for 8sp & 9sp (comes with the hub) and for 10sp you need the Mavic spacer plus the Shimano spacer.

Correct me anyone if I am wrong.

I've just put the 9 speed cluster on the 10 speed hub. I used a spacer from an old 9 speed cluster and it fits perfectly. Went for a test ride up and down the street and it shifts perfectly as well. BTW, it's a Shimano hub/cluster.

The wheel had a 10 speed Dura Ace cluster and used a medium and small spacer to keep it tight.

My fixies got a low BB too. Always an adventure.

Anyone just see Malcolm Mclaren on Denton? That was Interesting.

yer, if only all those emo kids knew that the grand daddy of their music and the inventor of punk is a quaff slightly incoherant pom who talks like hes as camp as a row of tents!

in all seriousness was interesting though, hes had a massive impact on modern society, would have been good to see him talk un jet lagged.

jock 07-10-06 05:14 PM

On the bike this morning I've got a fairly cracking pace up and I go past this dude who's struggling to make 20kays up a small rise. He catches up with me a little later at a set of lights. Brief chat and we're off. Ahead is one of the more painful and dangerous little climbs, with cars chopping and changing all over the place, drivers getting aggro with each other and innocent cyclists.

The guy clearly wanted a ride partner for that section. I wanted to keep the pace up and complete my quota of suffering. So I left him in my wake to fend for himself.

So what should I have done: do the social thing and ride with him for a chat and risk getting tangled up in commuter hell, or stick to the training plan and let him sort out his own problems?

Thylacine 07-10-06 05:24 PM

Yeah, I saw Denton last night. During the first 10 minutes I thought MMc was an amazing character, but then I felt a bit sad for him because he just seems so far removed and detached from everything.

HDTVKSS 07-10-06 05:33 PM

Jock, IMHO i think in that situation you need to look after yourself. your riding to a training plan and its probably safer riding alone at a good clip than relaxing and adding danger to themix by not concentrating 100% on what your doing + adding in the variable on an unknown riding partner.

Yep, saw it. He is a strange cat, thats for sure... I liked the Kevin Spacey interview before him too.

You did the right thing...I rarely want to do the social thing at the moment cause I have a limited time to get all of my training in. I get up at 6.00am cause there's less people/packs to get caught up in. After October I might change things, but for now I'm not prepared to drag anyone elses b*tt around Beach Road.

It's all clear to me now. Thanks for clarifying that up. I was thinking there was something wrong there, ever since I read the DaVinci Code and those clever Iraqis bombed the World Trade Centre.

How did you NOT get flamed for this???

Because they know if they flame me I'll sick Hitchy on to them.

Plus......I'm right. :D

So basically, you'll never see me on anything with any angles approaching 74-75 degrees. Maybe a track bike if I ever built one, but never on the road.
:D

I assume you like Kennedy's idea about the long stays? Is anyone else doing it?

That Scapin I had must've had a 74+ degree headtube -- it was so twitchy that it was almost dangerous.

When I bought one of the aluminium Taiwanese robot frames off Kennedy a few years ago, I'd been mainly riding my Ralieigh, which has pretty light steering. This Kennedy import (the guy who painted it reckons it's a Norco :)) has heavier steering, and I complained to John that it made the bike feel slow, blah, blah, even though I liked the stability.......but after I got used to it I realized that something like 73 degrees is MUCH better than trying to get my bikes to feel like the track bike I had when I was 21 :p

I think if you're tall, you should have longer stays. The further back you sit (ie: if you're tall or have long upper legs) the longer your stays should be. One length of stays does not fit all, which is what most companies seem to think. That makes no sense.

As for steering, 73 degree HTA with a 45mm rake will suit most people's tastes in not being too twitchy or heavy or anything like that. I like a certain trail figure in terms of handling, and I think that's part of what makes a Thylacine a Thylacine.

Of course there are other things to consider, too, such as bar width and stem length. They make a difference to how a bike feels and steers too, but people often forget about that. They think they can get away with an ill fitting frame and just put a longer or shorter stem on it and eveything will be roses. Doesn't work like that in my book.

Having said all that, I'm still living and learning. Road bikes aren't my main focus, but I'm not skimping when it comes to doing my homework and formulating ideas and giving them a go.

a head angle of 74deg on its own shouldn't make a bike that twitchy. Must've been a few other factors affecting weight distribution or the balance of the bike (or both).

If you take two bikes set up the same except for HTA (say one with 72HTA and the other with 74HTA) then with all other things being equal you should only really notice a difference at high speeds (typically entering corners on fast downhill runs). The bike with 72HTA will be marginally 'lazier', and that's about it.

531Aussie 07-10-06 11:21 PM

hmmmm............I see

531Aussie 07-10-06 11:29 PM

hmmmm.....I see

HDTVKSS 07-10-06 11:35 PM

riddle me this....

Mountain bikes are very much classified on HTA, XC race bikes typicly have a HTA of 70 - 72 degrees, whil my cannondale has a HTA of 69 degrees. My hard tail is in the 71 degree range and is noticably twitchier and also more nimble. this may also be atributed to weight and bike length, the cannondale is looonnngggg.

so , why is the given HTA for a " race geometry " so steep? is there any associated climbing benefits to a steep HTA?

jock 07-10-06 11:36 PM

Having said that, you will find bikes with steeper HTA are (generally) more responsive on technical ccts coz they will naturally turn quicker

Wilchemy 07-11-06 12:10 AM

Ummm isn't this "The Aussie Thread"...mindless drivel & all that? Wassup with all this technical bike talk?:D

climbo 07-11-06 12:31 AM

yeah, it's doin' my head in ! :(
