Geometry logic

[skollie]

Thinking of buying a new bike, but some say the one is more a "race geometry" and the other one not. Could someone please tell me whats going to happen to my ride if i change to the other bike, parts are the same as im buying? just the frame?

 

My Bike: New:

Head angle: 71 69

Head tube length 110 133

Top tube 587 572

Seat angle 73.5 73.7

BB to top seatpost 450 460

Chainstay 426 428

 

 

Both are medium allthough the frame is a bit bigger.

 

thanx

Geometry is one of the great big BS words used in bicycle marketing. Dont pay it a moment's notice. The colour is more important.

Yes, colour is very important!! No but seriosly - it looks like your gonna sit more "regop" on the new bike than on the old one.

Looking at the sizes, the new bike looks more upright and trail oriented... At the end of the day, Johan is right, get a bike that looks cool! Seriously though, ride it and if it feels right, then it probably is! I switched from XC to trail geometry and it took a while to get used to the new ride. I am much happier now though.

Just go one size bigger. And with the slacker head angle you will see more of the front wheel then usual and this takes an hour or two to get use to.

Ok good so as a "lucky draw" rider im not gonna miss the lucky draw just cause im not on a "race geometry" bike?

What bike are you considering? There aren't too many bikes around with a <70 degree head angle...

 

Downhill bike?

Right!

 

The theory - the new bike has a slacker head angle meaning the steering will be slightly less precise but the bump soaking will be better.

 

The shorter top tube on the new bike is because of the slacker head tube angle - very little difference between the two bikes here.

 

The rest is rather similar.

 

Generally speaking as you go from XC to trail to DH the angles slacken off.

 

The reality - unless you are a very experienced cyclist who constantly "reads" his bicycles you will only notice that the new bike is "different" - in which case colour is more important

 

More theory - if you are a hard core XC racer then upright angles are better - if you prefer comfort or hitting the jumps/sinlge track then slacker angles are better...
