Chainstay (or CS) is the size measured between the middle of the underside bracket and the middle of the rear wheel axle.
It’s one of many KEY BMX body specs to which it is best to concentrate.
Why? As a result of it could both enhance your driving or make it more durable to trip your bike.
Shopping for a body isn’t like shopping for a pair of grips, the place, if you are going to buy uncomfortable ones, it’s not that huge of a deal.
We’re speaking about a couple of $100s, so I don’t need you to decide on wrongly.
I did as soon as, and it was an excellent studying lesson.
This publish covers:
This brings us to:
Does BMX Chainstay Size Matter?
YES, it does.
In reality, there are a lot of riders (even execs) on the market who don’t care that a lot concerning the head tube angle, however they select their body solely by checking the CS size.
Earlier than we go additional to reply the next two questions, I’ll offer you a fast one proper now:
No chainstay size is best than the opposite as a result of it depends upon what you want driving extra.
So it’s kind of a private desire.
Is A Shorter Chainstay Higher?
If you’re extra into the technical avenue and skatepark driving, then sure, a shorter CS is method higher.
Execs of a shorter CS:
- It takes a lot much less effort to get right into a handbook.
- Subsequently, bunnyhops are additionally extra easy.
- It makes spinning tips so much less complicated.
- You’ll simpler whip your body round.
Whereas there are execs, there are additionally cons to a brief chainstay:
- The body doesn’t really feel as secure.
- You may shortly loop out.
From my expertise (I used to be driving Dan Kruk‘s signature WTP Network frame), it took me fairly a while to get used to the 12.5″ slammed CS.
It additionally actually depends upon how tall you’re. The taller you’re, the much less cozy a brief CS will really feel.
Is A Longer Chainstay Higher?
An extended CS is just higher for those who like extra stability, choose driving transitions and benefit from the movement a part of BMX.
Nonetheless, this doesn’t imply you can’t go technical with it – as a result of YOU CAN!
I preach this from my private expertise. I’m presently on David Grant‘s signature BSD Raider body with a 13.5-14″ CS, and I like it.
By the best way, I trip it at 14″ and don’t have any points with spinning. However I have to put somewhat additional effort into getting the body round when doing a tailwhip.
Execs of an extended CS:
- Your bike will really feel extra secure on the bottom and within the air.
- You received’t loop out of a handbook that simply.
The one con I see with an extended CS is for those who’re heavy into superior spinning tips. Or, usually talking, you like extraordinarily technical avenue driving.
I’m speaking about laborious 3s and laborious 5s out of grinds or pulling tailwhips as shortly as doable, like Johnny Raekes.
