the chain is specif of bikes with chain guides and is also directional . the inner plates that face the cassette are thin so it will work in the rear with std 9 speed spacing . ye the outer link are thicker for strengthPlease find me a single DHer that puts more force into a chain than a similar level road racer.....
BTW, thicker plates would require either a norrower inner or wider outer measurement. Neither would work.
Or XC UPhill masher/grinder for that matter. And as davep said, that thicker plate would only work on the smallest cog.Please find me a single DHer that puts more force into a chain than a similar level road racer.....

I'd say Sam Hill, but then again he doesn't need a chainPlease find me a single DHer that puts more force into a chain than a similar level road racer.....

Nathan Rennie, The End.Every single DH racer. Period. And even more so for gated racing.
Chains don't snap due to consistent and even force, they snap due to a sudden jolt of torque.
Roadies don't snap the chain tight out of a turn ever, really. DHers snap a relaxed chain tight as hell hundreds of times a ride. And gated racing...I've snapped plenty of chains at the gate. In fact, there was a time when Carter and King couldn't really snap a 4x gate 100% because the chain would just go....

1800 watts = 2.41383976 hp idk about this one..Nathan Rennie, The End.
The Australian Institute of Sport tested him at over 1800 watts, which blows away all but the most serious track racers in terms of sheer output, and he was using flat pedals during the test.
There is a brief on said chain on pg 114 of the Feb issue of Dirt. It's made by Gusset and is called the DHS-9. http://www.gussetbikes.com/gusset/products-mtb-information.php?id=CHGUDH9Hi was recently told that theres a dh specif chain on the market with thicker outer plates 9 same size inner plates) so it works on 9 speed cassettes ..
any one got a name for it ? link any info .
id be int this if i could find it
The PG970-DH is a beefier steel cassette w/ individually replaceable cogs. With this set-up you can take cogs off to run less if that's your thing. Also, a bunch of people have had issues w/ fast wear or with bending the two largest cogs on the standard PG970. Perhaps more for the big boys or the guys who log tons of bikepark or shuttle miles.Dumb, just like that stupid DH specific cassette that Sram makes, the PG-970DH (A perfect DH cassette would be an 11-26 version of the PG-990).
Stronger than what?! A little background on your experience would go a long way.thanks for all the advice on how to ride my bike but im just looking for this specif chain .
HE!! Dustin I snapped 3 of 4 990 (non hollow pin) in the winter series last year. 1 on the wall, 1 before the last rockgarden and 1 in the pits getting after it towards the run up to practice.The thiner inner link/thicker outer link chain is..... well sorry I am going to say it, A marketting gimik. Your chain is still only as strong as the weakest link, and the link is only as strong as the weakest plate and pin.
Eggs, what chains are you wanting to outstrength? I am curious what your snapping myself.
I weigh in at 245, and I run the Sram hollow pin, best chain I have ever run.
Installer error???HE!! Dustin I snapped 3 of 4 990 (non hollow pin) in the winter series last year. 1 on the wall, 1 before the last rockgarden and 1 in the pits getting after it towards the run up to practice.
Snapped another recently, had to go to Bobs and buy another 1.
Doesnt have to do with the bike either, snapped a couple on the Karpiel and 1 on the bullit as well.
LMAO! Yeah I put it in upside down!Installer error???
Just kidding, but I do remember there being a bad batch of chains in circulation.

Mine arent off drops always though. 2 of them have been off drops and Ive killed 6 or 7 chains in 3 years. 4 last year alone.Any DH bike that has chain growth as the suspension activates will put a lot of load on a chain. Lot's of DH bikes have chain growth at some stage in their travel, so all of the riders weight can be put onto the chain as the rear wheel tries to pull against it off a drop. Same if the brake is on when hitting bumps on some bikes.
Or 7 speed if you can find the stuff.Go 8 speed. Chains for that see to be stronger.
Rennie has enough power to kick a puppy through a brick wall.
Just kidding. The puppy explodes.
but, you are a big guy on a bike with a lot of rearward axlepath. That could be a major part of the problem.Mine arent off drops always though. 2 of them have been off drops and Ive killed 6 or 7 chains in 3 years. 4 last year alone.
A 7spd chain and 8spd chain are the same exact thing. The standard spacing for a road bike just went from 127mm to 130mm to accommodate the extra cog. Not difference in the chain...(well except for IG vs HG but that is a debate to have w/ Shimano techs)Or 7 speed if you can find the stuff.
also, we're pedalling bikes that are two or even three times as heavy, through mud and dirt with high rolling resitance tires. I think with all that working against a DH bike, the force on the chain would be higher.Every single DH racer. Period. And even more so for gated racing.

Plus the average wieght of a geared-up DH'r is about 40-60 pounds heavier than the average roadie or cx racer....fat roadies go slow and make ice cream stops on their rides...also, we're pedalling bikes that are two or even three times as heavy, through mud and dirt with high rolling resitance tires.

Doesn't make any difference. Supposing a top roadie puts out 1kW and a top DH rider 1kW, the force on the chain is identical - the mud etc just makes the DHer go slower. The other conclusion suggests that the roadie is holding back, which renders the comparison between their peak power pointlessalso, we're pedalling bikes that are two or even three times as heavy, through mud and dirt with high rolling resitance tires.

Yes, but even the fat roadies have to climb back up; we take a chain or truck. Oh, and how many Dh'ers also take a "smoke" break or grab a beer between runs Though ice cream mid run would be rather nice. Someone better get on that! Too bad that DQ is down the road from Diablo and not right at the entrance to Alpine/Domboo.Plus the average wieght of a geared-up DH'r is about 40-60 pounds heavier than the average roadie or cx racer....fat roadies go slow and make ice cream stops on their rides...
8spd chains and 9spd chains are identical except for the width of the inner bushing. The outer plates are the same. If anything, they'd be stronger b/c the pin is shorter.
