Sam Song Posted January 2, 2023 Report Share Posted January 2, 2023 Anyone running these on their trials bikes? I am planning on running this on my street trials hardtail as this is one of the only decent chain tensioners available right now. Colab Chain Tensioner | Reverse Components (reverse-components.com) The only challenge I see is that they specify running these with multispeed chains whereas I was going to go singlespeed chain And it shows the sprocket compatibility of 13-17, but I was going to run it with 18T in the back. Do you think I would be able to run this with an 18T sprocket in the back? Quote Link to comment Share on other sites More sharing options...
La Bourde Posted January 2, 2023 Report Share Posted January 2, 2023 I don't know how good is this Reverse tensioner. Did you consider the Rolhoff ? https://www.rohloff.de/de/shop/produktdetail?tt_products[product]=605&cHash=9ef08bf21b365a39a9d7503c8109781c It used to be the best chain tensioner years ago. The range of supported chain line is quite wide. Quote Link to comment Share on other sites More sharing options...
craigjames Posted January 3, 2023 Report Share Posted January 3, 2023 You can probably space the cages and jockey wheels to make it more compatible with wider chains. The main issue you might face is the clearance of the top jockey wheel to the larger 18t sprocket you're looking at running. Quote Link to comment Share on other sites More sharing options...

As Craig said, the issue you're likely to encounter is the top jockey wheel. I can't remember which brand it was (maybe Trialtech), but a while back a company offered their tensioners in 'Short' and 'Long' versions. The Long version is basically what you can see with the latest gen Trialtech tensioners where the main tensioner arm is fairly long, and allows you to run larger sprockets. The Short version had a stubby tensioner arm similar to that Reverse tensioner, and the sprocket range was basically the same as the one Reverse mention there.

Well unfortunately, I only found about this information after I had placed an order so it is currently on the way. Haha Probably not worth the shipping cost back to return, so I will at least attempt to install with an 18T sprocket in the back and see what happens. I will update the thread afterwards. 1 Quote Link to comment Share on other sites More sharing options...
La Bourde Posted January 4, 2023 Report Share Posted January 4, 2023 You can replace the upper pulley wheel with a smaller one: a 10t instead of 11t shall slightly increase the clearance. 1 Quote Link to comment Share on other sites More sharing options...
La Bourde Posted January 4, 2023 Report Share Posted January 4, 2023 Oh and there is this solution too: wolftooth roadlink https://www.wolftoothcomponents.com/products/roadlink This is like an extension of the rear mech hanger to allow usage of wider range cassette on a road bike. That shall do the work. 2 Quote Link to comment Share on other sites More sharing options...
Sam Song Posted January 28, 2023 Author Report Share Posted January 28, 2023 The manufacturer is right. The 18T will not fit with this chain tensioner. But with some modding, it can work. I took out the roller first roller for the chain wrap since there is enough chain wrap. So I am only using the downward tension. With this set up, it is woring beutifully. 2 Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 30, 2023 Report Share Posted January 30, 2023 Holy smokes that back tyre looks meaty, haha. Think it's the rim that really makes it look chunkier. Glad you got the tensioner to work one way or another 1 Quote Link to comment Share on other sites More sharing options...

Haha I'm more trials than street, but have a look at the Maxxis Aggressor. It's easily as grippy as the Jitsie Reverz, weighs very nearly the same (+40g if memory serves), and rolls as nice as a Holy Roller. I've not had a single pinch with it (worth noting that mine is the EXO skin one). Grabs corners as well as the best purpose-made trials tyres I've had, and seems to last a LOT longer. It comes in 2.3, but on a trialtech rim I measured the Jitsie carcass width at 56mm and this is 52, so hardly worth worrying about. Best of all, it doesn't have Jitsie plastered on the side of it! I think they've gone up a bit since, but I got mine for £36, so a nice bit cheaper too! Not cheap, but a good price for a genuinely premium tyre.
