Building up a Canfield Tilt and can’t fight the urge to try it SS. My friend lent me a Surly Singulator tensioner.

1. What is best way to size chain length?

2. Will the Surly tensioner work on the Tilt? Don’t want any damage etc.

3. The Surly tensioner can be mounted in “push down” mode or “push up” mode. Essentially pushing the chain down or up to create the tension. Was going to do push down mode but wondering if either one is better for a FS application.

Any other FS SS tips are appreciated.

That bike has way too much travel for a Singulator, you’re going to have to use a derailleur or something spring loaded. You can’t lock the chain in place on something like that because the suspension travel affects your chain length too much.

Ahh rats. I was getting excited to try it out. Makes sense though and glad I asked.

I posted on the Canfield forum about these tensioners as someone had one on a 1.2 build but no replies.

The one below says 13 or 14T sprocket sizes.

This one says 11-17T. Not ideal as I would want to run at least a 20T, if not 21T.

I emailed the company about cog size but never heard back.

SB One tensioners are primarily for DH bikes which is why they fit such a small cog size, it's too bad because the clutch would be a nice feature. The bad thing with most two pulley tensioners (which you need for most FSSS bikes), is that cog size is limited.

I have run a Rohloff tensioner with a 20t cog and the teeth just barely clear the pulley. I actually like this since it acts as a snub while also tensioning the chain. I can't think of any other tensioners that have more cog clearance than that.

That said, the Rohloff tensioner is a fantastic tensioner that I've used successfully on several different bikes.

Which version do you use?

Chain Tensioner - Rohloff AG

Either the -15 or -10 (for 148 rear). The non-spaced version has a wacky chainline that is harder to work with.

The DH version has less cog clearance so I avoid it.

I ran a SRAM Force 1x short cage derailleur, and use stub of cable (cable end in where the cable ferrule normally sits in the Der. cable stop) to hold it aligned with the cog.

Works great, it has a clutch for chain retention, and the X-Horizon linkage design keeps it from moving left and right as the cage is tensioned and relaxed.

The short stub of cable can be seen in the image below by looking closely at the derailleur.

Origin8 makes the Torqlite UL that is a 2 jockey wheel tensioner. you can make it fit basically what ever cog you want. i have don't 22T in the past. it worked great in my XC FS bike

I run a Zee short cage rear derailleur, also with a short nub of cable to hold it in place. I've also used a shimano 105, and an old xtr short cage derailleur. All worked well, the clutch of the Zee is nice to have. Just adjust the B-tension screw to suit your cog size. Currently on 22T but have used a 25T as well

Rolhoff tensioner will work, but you'll have tons of chainslap. You may be able to increase the capacity of the SB One tensioner by adding a Wolftooth Goatlink to space it a bit further away from the cog.

I've used Rohloff XC on a pivot mach 4 and my Canfield Riot, haven't had huge chainslap issue once chain length was correct its got a really strong spring, but do have a wrap on the stay. Chainline required flipped DM ring on Raceface crankset. The Rohloff is really meant for their IG hub so chainline is out there like 55mm IIRC, provided spacers allow some adjustment( both 142mm rear). Max rating is 21t but that was a PITA to get rear wheel off now use 19t both bikes(28/19 about same as 32/21). The DH version must be removed to get rear wheel off from what I've read.

 

[Shinkers]

Rohloff improved the chain line with the -10 and -15 models but I do remember flipping my chainring when I had the non-offset version.

Didn't really notice any worse chain slap than you'd have with any other derailleur type bike, but I also shimmed the mounting bolt so that the tensioner arm was locked down and couldn't swing.

No, I don't think the YESS tensioners are easy to find anymore. I have an ETR-D on my Anthem SS and it is excellent. It does have to be removed to take the rear wheel out, but it's easy to do on the trail if needed.

The Paul Melvin tensioner looks good but states chainline of 44-52mm or 135/142 spacing. And it’s out of stock.

Ideally I’d like something simple and/ or cheap just to see if I like SS on a FS.

Been riding SS hardtails for 15 years, so I know I like SS. But have my doubts about a FS application even though the concept is appealing.

I'm using a Zee rear mech I had lying around on the Anthem.
The last 2 seasons have been 1x9 and 1x10 gearing and with the season over I thought I'd see what it would be like SS.
I knew the rear traction wouldn't be a patch on the hard tail SS when climbing out of the saddle, but it's not bad. Not bad at all.
It's only 1kg more than the Kona Unit, but feels heavier when you're swinging it up over a gate.

check out the shimano Alfine tensioner or there is a ztto one on eBay. Main thing is you will want the 2 idler wheel options. If you like it, then look for a higher end one or just ride what you have.

Quick search showing Alfine only has a 41.8 chainline.

Back in '00 when I first started singlespeeding, I ran a Campagnolo Super Record RD as a chain tensioner.
I took some flak for that but it worked perfectly.

It's slightly adjustable, but only a few mm.
