Post your mtb SS

slightly OT (and probably OTT too lol) sorry if this has been posted in this thread before.

 

but have you guys seen these? They seem VERY popular amongst DH and FR riders who prefer SS on their big bikes.  Super nice piece of kit imo...the g3 clutch version is around 200EUR though, the non clutch version is about 75. The ultimate chain tensioner? The way that it works and adjust for chainline seems like the best possible way too. (The whole cylinder body slides inside a clamp)

also available bit cheaper a bike-components. de I see.

That is a seriously nice piece of kit, but that price!!!! 

I know some SS builds that are eye-wateringly expensive, and this will be perfect for one of those.

 

Ultimate simplicity still wins for me, sliding dropouts with tugs. Clean and simple

Thats kinda sexy - but its expensive and not exactly light.

^ 160g is not exactly heavy though lol.(EDIT: thats lighter than a XTR level derailleur by almost100g) the rapide type ones are all100-120g and they are clutchless. imo this opens up a whole lot more frame choices (vertical dropouts) and considering the amount of cheap and nasty tensioners alot of people use on ss builds....this one would be a no brainer if i built aSS on a vertical frame again. Apparently they also don't have that horrid skip that the el'cheapos give you under load...and works flawlessly with oval chainrings obviously

Compared to a Surly Singular or Paul Melvin 109g  (actually cheaper) it is though.

 

The cheap SS double pulley tensioners are essentially ‘clutched’ and they’re around €20-30. 

 

I used a singular with a oval no problems as well - there is actually very little change length change. Also the tension on that is variably set to riders preference. Same with the DMR Tensionseeker 2. 

 

But I agree its not wildly heavy - But as a bit of a weight/money weenie its sort of out of the ‘inner circle’ for me.

 

It reminds me a lot of the YESS tensioners. 

 

I prefer tensioners over track ends - but good sliders are definitely the SS sweet spot.

yea...51g? for obvious superior tech? no brainer for me

 

take 51ml less water? cut your hair? go commando?   

[Mattwalt]

LOL - Loose 20kg of body mass...

 

But its the cost as well...

 

Any idea of how easy its to remove the rear wheel with it fitted. Many can be a real pain in the #### to get the wheel in and out. A simple easy to use system would possibly over-ride my option.

lol yip. luckily I don't have 20kg to lose, but i'm sure I can muster 51g if I try haha.

 

EDIT: I think (or it looks like it) works like a normal derailleur in terms of tensioning so it would be like taking it out of a 'normal' geared setup

 

 

around 2:15 (Nico Vinks's FR bike)

My 2 most recent builds. 

 

 

 

 

[Mattwalt]

The top bike is using a double pulley tensioner - Usually with those the cog ‘binds’ on the top pulley which can be a little frustrating getting the wheel out.

 

Singulator (pull up mode) is easier but the ‘quick-release’ can get in the way in some cases using the spacer for tension can be fiddly...

I still think  the cleanest solution on a vertical drop out bike is to run a guide / tensioner at the crank. Nice and clean, easy to get the rear wheel off and amazingly adds very little resistance to the drive train ... that v crank would spin freely like nobody's business.

 

If you do not have ISG tabs on your frame, but use an external BB, you do get adapters that fit between the frame and BB that accept an ISG mounted guide.

yea those work nicely if you have a threaded BB. You are screwed as per usual with anything BB30 or pf30 without ISG. They should just make external bb's compulsory...

I dunno.... I would never build a SS on a non SS frame.... 

 

A SS DH/Enduro bike in SA without uplift would be death.

 

I know because I rode a converted drop out Blackmarket Killswitch as a short travel SS 650b trail bike for years.

If you have these, the whiskey (now squid bikes) 'oner' solves all issues by turning your oversize BB shell into an EBB

yeah forgot about EBB's in pf30 frames. Niner also makes one for R1bilion lol
