Raleigh '09 FS

Hey AverageGuy, I'll glady throw a leg over the new Proto and test it for you. Like I said, I take my hat off to you for going with an active design when the general marketing trend is to say "Platform"

 

As someone here said already, It's not the bike that bobs, it's a rider. Your legs moving up and down creates harmonics that needs to be cancelled. Usually this is either chain tension, a heavily damped rear shock , or a combination of both.

 

Good designs use a combination of both. If you are going to use chain tension to excessively then you run into drivetrain problems, chainsuck sensitivity yada yada yada..

 

Suspension bob is not necessarily bad if it si controlled enough for the rider not to notice.

For my personal taste, I think the raleigh looked a little active for my taste but after riding it, I could change my mind. However there are bike that show excellent control of suspension movement whilst still providing bump sensitivity. It all depends on which side of the spectrum you want to lean toward as Designer or rider.

 

Alberts new bike clearly does not slow David down. I just think it could be more controlled, but that is my opinion based on what I like.

 

I have tuned my Rush rear suspension to be quite bump sensitive without sacrificing it's control of my legs reciprocating action. Thats what I like a bike to do. Other people have different ideas.

Well said. You can also add maintenance.  The more links in the system the more bearings you have to worry about.  That is the beauty of single pivot frames but you must know that you sacrificing performance for simplicity. 

 

OXy

 

Here is have to disagree.

 

There is a lot of marketing blurb around the performance of Linkage type systems. It's just that, Marketing blurb. The only place linkage systems outperform well designed single pivots is on paper. On the trail there is a different story.

The key factor that determines the performance is the main pivot location and the leverage on the shock. everything else is just to push the shock and tune the "feel" that riders talk about. But this is not suspension performance per se.

 

Wheelbase, chainstay length BB height, front centre all these factors help to determine traction, suspension still has to work within these parameters. The numer of links is irrelevant except from a Maintenance and LAteral rigidity point of view.

GoLefty, I am a big fan of single pivot designs especially the Santa Cruz Superlight.  But I must also admit a soft spot for virtual pivot bikes. Embarrassed

Smile Virtual pivot bikes are always marketed aggressively so it becomes appealing to want to own one. However none of them are marketed with any substance.

The lovely thing about virtual pivots bikes is that the designer can change teh feel and look of the bike by moving a few pivots around. It's harder to get that right with a mono pivot swing (Super Light, Rush) or a mono pivot linkage (aka Kona, Scott Spark, Cannondale Rize). The good ones are start to look alike..

With virtualpivots the position of the pivots can change but if you look at the axle paths they all resemble a good mono pivot. Yes there is a subtle mm here and there but that makes zero difference. What you feel through th seat of your pants is the leverage on the shock.

 

But linkage bike do look sexy, unless you are mud, then it looks like a taxiLOLLOL

Talking about the Dale Rize, looks like on sweet bike.

 

I see MTBR just gave the Prophet 10/10 in their trail bike test and 9/10 for the Meta 5.5.  

 

BB.  If I can find a Specialized Epic frame with V-brake bosses I will consider it purely due to the fact that it will look good hanging next to my <?: prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />Roubaix.  LOLWinkShocked<?: prefix = o ns = "urn:schemas-microsoft-com:office:office" />
