This xt 760 in short form-would work just fine
and Rapid rise derailleurs are out of favor
So they would be cheap-maybe $20 -and that might include shipping
Nothing wrong with your idea
if you use a rear derailleur you have the option-eventually- of switching back to a geared bike
single speed bikes-are somewhat limited-but each to his own
Yeah they should be cheap
and the POS nashbar single speed chain tensioner I bought-years ago-was a POC
Of course for $1o(on sale) what about what I should have expected
Luck

PS This RR will actually shift up into that 41 cog-in the BIG OR MIDDLE FRONT RING- hard to believe but it does
PPS- WOW- you folks are in high form today-you make ME look good natured
Usually just LC vs FRAP brings out this sort of venom
or maybe some Quirky French bike VS any other bike in the world!!(ok I kinda like french stuff-but I hate their quirky threading bass ACKWARDS PEDALS- funny sized stems-seat posts)

repeat Rohloff, chain tensioner, Definitely not cheap @ $85. Universal Cycles -- Rohloff Twin Pulley Chain Tensioners
I own one of these, the chainline is a shim washer stack to place the pulleys (made by Tacx) under the Cog.
nor, for $6 less, is the USA made one from Paul Comp https://www.universalcycles.com/shopping/product_details.php?id=336&category=2622
though this one at $26 is getting down there in cost Universal Cycles -- Q2 Chain Tension Master

by the way stubborn bonehead, . you remove the wheel by pulling the Whole derailleur Back. its been like that way before you were Born.
just dont cut the chain too Short.

How easy would it be to pull the derailleur back on these? Seems like a lot of people use "too short" chains with tensioners.
You have to thread the chain through the cage if you want a derailleur to work as a tensioner
Somebody forgot to tell the guy with the picture in the fourth post.

Yeah it should work fine
and there is very little market for rapid rise derailleurs
Heck I was going to dump mine-
but it is worth soooo little-but still works fine
so pointless to sell
I notice the one in the picture-was a full length MTB type-not a short one-
but no reason a short one wouldn't work as well
since you don't really have to worry about "taking in LOTS of chain"-
And the derailleur will give you plenty of leeway to change to different sprockets-
and you can certainly pick up a good quality LX XT hell maybe XTR rapid rise for $20-$30-$40
And in the event that you return to the LIGHT- you will have a jump on converting back to multi speed
Who knows-RAPID RISE might have made a comeback by then??

PS Cheap is always good-especially when the parts were originally pricy like XTR or even XT- nice finish nice pulleys bearings-quality parts

Thanks again, Charlie. Yeah, that's a good thing about derailleurs - Shimano makes them with quality build. The cheap tensioners get so many complaints about springs and whatnot breaking. I've never heard of a Shimano spring breaking.
Actually, I'm not going single speed, but rather internal gear hub.

One application where low normal is still in favor is derailleur type folding bikes. They make sense there, because the derailleur is inboard when the cable is slack.
But to the point, a low normal has no advantage I can see for your application. I've used high normal as tensioners on IGH builds with no issues.
I am using a low normal long cage XTR from about 1999 as a tensioner on a mid drive, but that's a whole other thing.
Point being, derailleurs make perfectly fine tensioners whether they are low normal or not.

nobody said you have to use an 18t cog , you can use 2 smaller chain-wheels and get nearly the same Ratio..

Another bad assumption. I'm already at the smallest chainring size available for my bolt circle diameter. Or are you suggesting it would be somehow "cheaper" for me to replace the crank in addition to buying an expensive dual pulley tensioner?
