My current gearing set up is perfect for Cannock but lately I have been venturing further afield (Peaks) and have been left wanting at times. I do not wish to go away from 1 x 10 so I decided to fit the Hope 40t. It shifts up and down well enough but I do have a couple of issues.
If you run it backwards it drops down 2 cogs - pedal forwards back up it goes. If I look at the chain line it looks well off, which would explain the problem. What confuses me is, the cog is bigger, yes but it's in the same position as the 36t was so why would it affect the chain line and cause the back pedaling problem ?

Hi pal, when you put your t-rex on did you adjust the b tension screw ? if not here's a tutorial, this is a road bike but the same applies to mtb, just skip to about 1.17 min on the video

Yes I did thanks. In fact the 40t comes with a slightly longer B tension screw so it can be used with a Zee mech.

Interesting this. I've got a 2x10 set up but am considering the T-Rex  my climbing ability seems to be diminishing by the day. Would it work on a 2x10 or am I just being a wuss again? I'm ok for Cannock but am thinking of Degla etc.... Sorry to hijack Will. |

Should work absolutely fine on a 2x10 set up, may just need to adjust the b-tension screw to allow it to hop up to the 40t cog.

I don't like these T-Rex things myself!
I just seems unnatural to me.. Like dying your hair!

Thought you wont be back pedalling when you hit 40t cog? Ha ha yes i did say that. It's more the chain line that bothers me - it's not the deraileur doing it, it's the front chain ring is too far to the right. |

Fitted before with 32f ringmaster with spacer.. Works very fine with t-rex no backpedal issue.. But the muppet in me sold the ringmaster including the spacer.. Now cant set it up properly with RF 30t front. i might mean the "spacer" im referring to differently ..the right product name is in the back of my head  |

I was just playing..
You see them about a lot now!
I did mean the 'not natural' bit though. Surely, any mech is not designed to go to 42t!?
It may work but I can't see it doing a mech much good!
I've no doubt testing has been done and obviously people are using them so.... I'l just shut up!

I was asked the other day if I was gonna use an expander thing but as yet no climb has beaten me, in fact I would say going 1x10 has helped me get fitter, still running just an 11-36 at the back with 32t on the front, I can't use old age(51) as an excuse for running easy gears so for now I'm sticking with what I've got....in 6 months I'll probably cave in after the winter bog/snowfest lol

I like that way of thinking!
I've got the same rear as you but have 36t upfront and I've not been beaten by a climb yet!

Your not old 67 not that old mate At at least I'm just a fat git that's why I can't get up the hills  Plus do you think this will work with a triple set up |

Will I had one fitted (just took it off ) I had exactly the same thing happening never got to the bottom of it just leart to live with it I might put it back on if I go for some big climbs but for Cannock it's just making me lazy |

It seems to be a common issue with the Hope one. Doesn't cause a problem in use but I am going to fit spacers to the front ring to move it 2mm to left. It will improve the chain line and possibly sort the back pedal issue. I'll never use it around the Chase but it's nice to have i reserve when I go somewhere like the Peaks.

I assume your front spider / chainring is in the right position to start with? What was there originally?
The B tension really needs to be set with something like a 3mm gap rather than guessing the angle of the cage etc...

The B tension really needs to be set with something like a 3mm gap rather than guessing the angle of the cage etc... It was a 3 x 10 to start with and replaced with a NW and Zee mech. I do think the front chain ring is too far right, hence why I'm going to fit spacers to move it to the left. Wasn't noticeable when 36t was there which is a bit strange as the last/first cog is always in the same place. I've tried the B screw in all positions and it makes no difference to the back pedaling issue. |

The single front ring needs to replace the middle chainring and not the outer one. Is that where it is?

my climbing ability seems to be diminishing by the day.
