Shimano 105 LH Gear lever - double to triple?? Carbon query

daniel_b

Morning all,

my Felt (bought 2nd hand) has 105 (9 spd) throughout, and someone previously must have removed the smallest 30T cog, as it is just a double now, and runs on a fairly hefty 53/42, which is fine at present.

However, I will soon be swapping over the groupset with that on my Highway one (Carbon crankset and 105 10spd, which still has all three cogs.

I will then re-install the Felt kit onto the Marin.

The Marin is to be a tourer, and whilst I could get away with the 2 cogs on the Felt, I don't see it being possible on a potentially heavily laden touring bike going up some uber big hills.

So my question revolves around the current Felt left hand changer, ie it only moves far enough for 2 changes, so is it capable of shifting to an inner ring, or could somebody have disabled that feature?

I could of course take it to a bikeshop, having done everything else up until that point, but thought I would ask on here first, as all things considered, I would rather do it myself.

Also, while I'm here, I'll be refitting the carbon cranks, should I be buying a torque device of some kind to measure what pressure I am using to attach it?

Many thanks

Dan

from talking to people who know lots about this stuff, the shifter should be capable of being calibrated for a triple.

I have the other problem on my road bike. It has a double but is calibrated for a triple, meaning I have to shift once more than I need to sometimes to get the ring I want (invariably the smaller one!).

I haven't a clue how you'd go about it, but I reckon it can be done and also reckon theres no shame in going to a bike shop if needs must.

good luck.

Thanks very much CH, that's the type of answer I was after

I will have a crack, when i take it on, probably before Christmas, and as I have a very friendly LBS (And I just bought a bike from them) I reckon if I can;t figure it out, and took the lever down there, they might give me some pointers, or worst case i can just give it to them, and a wodge of cash, and ask them to make it work

Your miscalibration sounds somewhat of a pain though :?

If I find out anything useful I will of course post it up here.

Cheers
