Hi,

I’ve got some good advice here over a year ago and so here I go again: planning to buy a cx bike from 2016 and slightly hack it. It currently has a Shimano 105 rear/front derailleur. Cassette is an 11speed 11/28 Shimano. Crankset FSA Gossamer Cross, 36/46. Do I have any options for going below the 1:1 ratio?

Thanks.

Get yourself a Wolftooth and use a medium cage 105. Got a 36T SRAM WiFli sprocket fitted to the rear of my Shimano set up, running well.

Yep.
Yep.

You should be able to switch that model rear derailleur for yours quite easily.

I think I’ve used it twice, and only when loaded with 50+ lb of gear. It is a touring bike.

It’ll mean major surgery: a 34 inner ring, a 34 cassette and a long-cage derailleur – or a wolf tooth hanger to lengthen it. You should be able to get up most things on that…

Really?

Really?

Any idea on how to locate it?

PS: is this the one?:

Yes.
Yes.

There’s an article on road.cc about setting that up to run something like 11-40.

That’s a 0.70 ratio, WOW,
That’s a 0.70 ratio, WOW, that must be cool.? I love my Cinelli at 0.75. Huckfinn hope you get it below….

The old 105 derailleur
The old 105 derailleur probably won’t go too far past its published capacity but if you get yourself a Wolftooth Roadlink or something similar you should be able to fit a far bigger cassette.

Alternatively switch out for a new 105/grx/ultegra Rx deraillieur and you should be able to get 11-40 working easily without too much bother.

There was an article on here
There was an article on here saying you could run 11-40 on 11-speed 105. Personally, I’ve got a 50-34 compact and 11-34 11-speed 105, which generally does me fine (and I’m rubbish at climbing 🙂 )

My Jamis touring bike came

My Jamis touring bike came with 105, circa 2013.

24/32/42 front triple.

12-30 10-spd cassette, changed to 11-34 when it wore out, no shifting issues. 24-34 is good for vertical walls or pulling tree stumps.
