Hi,
Ordered a rohloff conversion for my ICE trike 20”. The range doesn’t quite give me what I want on a single ring. Will the rohloff tensioner cope with a double up front 10t difference? Tia

Re: Will a Rohloff tensioner cope with double ring
Check out what tiger bitten has to say on the subject - he runs a double sprocket, double chainring on a rolhoff I think
A shortcut has to be a challenge, otherwise it would just be the way. No situation is so dire that panic cannot make it worse.

Thank you. I’ve searched tiger bitten but only 11 results come up and non are rohloff related. I’ve searched rohloff double chain ring as well. Thanks.

My error - I knew this as well, he has an HSD up front.

I changed to a Rohloff hub from a derailleur system and kept the old rear mech with no problem using a triple chain set using the big ring and the middle ring. I used the small chainring to take the pressure of the chain when I folded it. I have a 26” rear wheel.

Pictures from Rohloff's comprehensive handbook (2008 edition) on the subject.

Re: Will a Rohloff tensioner cope with double ring
When it says 10 links, it means 10 full links.
So it will cope with a 20 tooth difference between rings.
I'm fine running a 38/55 double.
I think the best way to set multiple chainring up is to use multiples of 1.136 as ring spacing.
That sets a front change as almost exact rohloff gear spacing.
So 1.29 for a two gear step and 1.466 for three.
If you want to setup a triple for 4 extra gears then a road triple 30/39/50 is very close to ideal and matches up well with a 15 or 16 sprocket to keep it within the recommended torque range.
Luck ..........

Re: Will a Rohloff tensioner cope with double ring
Yes. See my Sprint with 50/34. I have a 19 tooth Rohloff with standard tensioner at the rear.
I know it’s got a motor; the 34 is there just in case I run out of battery. I fitted it after a ride where I ran out at the bottom of a number of steep hills in the local Peak District. It’s what I had on the trike before I had the motor installed. 34/19 in first gear enables me to climb just about anything albeit very slowly.
