View Full Version : Devinci 8F8 24" rear wheel...head angle? bb height?

I'm wondering if anyone knows how much the head angle and bb height changes by switching the pivot to the 24" wheel position? I'm guessing HA 1-2 deg and BB maybe +/- 1"
...anyone know?

thinking about using the 24" pivot location with 26" wheels to steepen the head angle and raise the BB a bit...just curious to find out what the difference will be.

I don't know anything about the bike, but I think that would steepen the geometry a bit. You might run into problems like the rear wheel hitting the seat mast at full compression, though? I'm not too sure, but I'd guess that would be a consideration.

Ok,

You can run a 24" and have next to no change in the bike's angles/bb by using the 24" pivot point hole, that hole was put there for a reason, it gives you the ability to run a 24" rear wheel and keep everything kosher. Running a 26" in that position though, will most likely cause interference problems. Change the shock from the 8" to the 7" position and see how that feels.

digging up an older thread...

I moved the rear pivot to the 24" hole, still using a 26" rear wheel. So it basically raised the BB about 3/8" and steepened the angles about 1 deg. It also shortens the chainstay to 17". Bigger tires than 2.5" Kenda would probably rub the chainstay.

not a huge difference, but nice if yer not dh'ing all the time.

yeeaah i dunno if you should be doing that. listen to what people say about seat mast and tire.

bigwheel, there's a reason why that hole says 24" on it. Better get Wayne or NSTP in here to fix this.

I rode it that way all summer with no problems. No contact between tire and seat tube at any time, even under full compression...changing to the "24" position only moves the rear axle 10mm closer and 25mm lower in relation to the BB. Not a significant difference in "axle-to-seat tube" dimensions between the two positions.

I know the reason for the 24 hole. There's nothing to fix. I'm not 8 yrs old :)

True, big wheel is correct, a lot of people have wondered this. There is really no problem.

what he said. plus, it will steepen the HA and raise the BB a bit.
