So the hype is big on the 1 x whatever drive train bandwagon.......

[deanbean]

I was riding a 1x9 with a BB mounted Paul chain keeper , I found that I was loosing the chain, that's with a X0 med cage der and an SLX chainring, Changer to a Truative chain guide http://cdn.sram.com/cdn/farfuture/j77Nij78NzeoK-g5ly2uSqI_V1FCHcWg00KdkYcB6kU/mtime:1372788203/sites/default/files/images/products/accessories/2012-x0_chain_guide-large-en.jpg, and SLX clutch der, and it is secure now, that's with a fair bit of riding over rock gardens (chasing meercats over the last weekend).

Awesome thread Hairy and a place wher I can raise another question.

The 42T chainring that cost R1000 to buy, why can we not take a 36T off of a cassette have it drawn in Cad to a 40 or 42T and lazer cut the bugger.

Could probably get 10 for R1000, yes you will need to sit and file the teeth a bit but it could also be made in S/s or Alloy?

Anybody else thought of this or done it?

 

Steven, you can do that with a single ring...so nothing that has shaped teeth and ramps/pins to pick up the chain to move it to a bigger ring.

 

That said, that is a moer of alot of filing you have to look forward to...why not CNC the bugger?

CNC is an option but need to find someone who could possibly lend a 42T chainring to get the measurements off of. Then a sample can be made, tested and then from there these could be sold at a much reduced cost. Say R300-R400.

Im big on this wagon, converting all my bikes to 1x1..... I do not own any geared bikes anymore, haha

So the hype is big on the 1 x whatever drive train bandwagon.......

 

I have been running a 1 x 9 for a little while and it has it's pro's and con's, the more dedicated drive trains with a narrow wide ring, clutch der and cassette with moerse big cogs certainly does have an appeal and makes sense ..............but ...........

 

A chain ring does not last long, more so on a 1 x set up as you are only using the single ring vs sharing the wear on a dual or triple chainring crankset.

 

 

Narrow wide chainrings are also not exactly a cheap purchase.

 

So then, why not get a S/steel SS specific chainring for around the R350 mark and run the 1 x set up with the biggest moerse gear range cassette that works for you and then use a chain guide with a clutch der?

 

Just thinking from an economics stand point here.

 

Edit: Font size amended

 

 

Because the chain you run has to be compatible with a 11speed cassette (assuming 1x11) and therefore a single speed chain ring is too thick. You still need a 11speed chain compatible chainring.

 

Personally, I would simply go 1x14. In fact I am strongly considering the 1x14 route now that 1x11 is more expensive than 1x14

[Hairy]

I am curious RE your 1x14 reference

[Pieter1]

Wont a SS chainring be to thick for a normal chain?

[Hairy]

you get varying thicknesses for the SS rings.

[GoLefty!!]

But none are thin enough to handle a 11 speed chain.

 

 

Hairy 1x14,.............one word.

its what I'm considering for an all mountain type bike and my next XC Bike.

One thing I don't like about a Rohloff is the massive unpsrung weight you add to the bike (if you have a full suspension). Most rear suspension designs weren't developed with a 5kg (all in) rear wheel weight. The heavy rear wheel will also affect how the bike handles in the air. Rohloff also does not offer through axle options, so you become very limited in terms of frame selection. Most All Mountain frames come with 12mm thru-axles. The same goes for #endurospecific frames .

 

Personally I think that the Pinion gearbox is the way to go in terms of internally geared systems. Nicolai and Alutech who build Pinion compatible frames can do custom geometry as well.

 

Don't get me wrong. The Rohloff is great for touring, long races and rides such as freedome challenge etc, but I definitely think that a deraileur system is more suited for All Mountain riding.

Aaaahhhhh .. but that is moss moerse expensive and heavy .... the Shimano internal geared hubs seems to be tough as well.

What was very evident when going from geared to SS on the HT was that the back end was far more playful and flickable with it being lighter.... so yes, I would also be interested to see how it would feel with a heavy hub set up

[SwissVan]

Anyone know when road bikes will begin the mass movement to 1 x 10 /11?

I hear you hence this is still exploratory. I've asked Rohloff about a thru axle version. Apparently they're working on it....
