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. 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: |
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. |

Freehubs for Shimano 8 & 9 speed will do 10 speed with a spacer added (comes with a 10sp cassette.) 10 speed specific hubs (like the Dura Ace wheels) will only do 10sp as they are too narrow for 9sp. 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. 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. |

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? |
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.

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.

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. |

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 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. |

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

hmmmm.....I see

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? |
Having said that, you will find bikes with steeper HTA are (generally) more responsive on technical ccts coz they will naturally turn quicker
|
Ummm isn't this "The Aussie Thread"...mindless drivel & all that? Wassup with all this technical bike talk?:D
|
yeah, it's doin' my head in ! :(
