Would really appreciate it if you could take a second to let me know what cranks you are using and how many chainrings you are running on them.
Thanks in advance, P

Couldn't agree more 😉
X9 triple, HT2 Lx triple, Veloce double.
kona stinky- saints 1 ring and guide
spank smoke profile 3pc cranks 25t sprocket
"gears are for queers" eh, aracer? 🙂
why tho. who are you ? who are you doing research for? whats the objective you are trying to achieve?
why?
I'm toying with a prototype chain device and want to test it with different cranks. I'm thinking I will test it on the 3 or 4 most popular and see if I run into any compatibility problems. Have not had any luck finding sales figures for cranks though so thought I would just ask people.
Thanks for the replies so far - keep them coming!
Race Face Deus XC with bash, Granny and middle ring on but no front mech so only use middle.
who are you ? who are you doing research for?
I am Packer and I'm doing research for myself. Don't work for a bike company or anything like that.
SLX, 22,32,44
X0
XT with a single 38T ring in the middle position, for my Rohloff.
SLX with a 46T Gates Centretrack sprocket mounted on the outer position on my SS.
If you can come up with a BB-mounted spring-loaded chain-device that applies a constant force through its movement I'll have one.
XT Double x 10
Deore triple x 9
XT double
105 double
Shimano SLX with massively filed down chainring tabs to fit my old e*thirteen device. Single ring always.

Not what I am working on, but have you tried the [url= http://labs.yesspro.com/products/etr-b ]Yess ETR-B[/url] ? I had one and thought it was great.
XT double x10
XTR M970+single ring
XTR M970 + double'n'bash
SLX + single ring
Shimano SLX with massively filed down chainring tabs to fit my old e*thirteen device
Why did you have to file them? Was it because the bashring was too chunky around the chainring bolt area?
XTR 970 single ring
XTR 960 triple
XT 770 x 3 - 2 single ring, one triple.
but have you tried the Yess ETR-B
No, cos it doesn't do what I'm looking for. I want a tensioner that will take up the slack on a full suspension SS bike, AND applies constant force through its stroke.
does the Rohloff DH tensioner do that ir_bandito - worked ok with my Giant nrs.
Shimano SLX HT2 175mm tripple
SRAM/Truvative S1000 3.3 BB30 175mm tripple

Is it possible for a tensioner which uses a coiled spring to apply a constant force throughout it's stroke? I'm not sure it is, and I can't think of how else a BB mounted tensioner could work.
Two sets of XTR M970s, one set Truvativ Noir carbons, one set FSA Gravity Lights. One of the XTRs is double, the rest are singles

The cranks were ones that came with the bike.
If I was in the market for cranks I would be getting SLX cranks. Single ring die-hard though.

Nope, coiled spring won't apply a constant force, which is why I was hoping you'd be designing a system that would.
Belt-drive needs constant tension y'see....
XT M770, single ring, 34t
XTR triple and Hope BB- Hadtail
XTR double and Hope bash and Hope BB- FS

I'd be surprised if this thread is representative of mtbers in general. Lots of Middleburn mentioned but I don't see that many of them out on the trails
-M770 XT, double and bash with ISCG Stinger
-M800 Saint, double and bash with ISCG Stinger
-Raceface Ride, double and bash, no device due to position of granny bolts (fouls on stinger type devices). Had same problem with RF Evolve XC, I understand some RF come with plastic shims to fine-tune the chain line.
-SLX, triple. Probably get doubled at some point.
SqT Middleburn RS7. 32T Renthal Ring.

Always double on the road though..
