the unofficially cool MTB drop bar thread

[Dale cannon]

Here's mine.

Looks kinda familiar. :mrgreen:

Great job, it looks superb.

Now get those bl**dy bars wrapped.

Already done!

Already done!

Thank goodness, I can sleep sound in my bed.

So to clarify,

You'd need to swap the mtb front mech for a road triple front mech but the mtb rear mech would suffice.

Food for thought.

I'm pretty sure chainring spacing is the same on road and mountainbikes.

I can't think of a specific instance but I'm pretty certain I've fitted mtb chainsets to road/touring bikes in order to lower gearing and road chainsets to mountainbikes to increase gearing and never had a problem with indexing.

Obviously the shifter has to have to right number of clicks, ie a road double sti/brifter won't be able to shift between all three rings on a triple ring mountain bike chainset.

Infact, I'm also pretty sure I've set mountainbike triple shifters up to do road doubles (think flat bar roadbike conversion) and just used the limit screws on the mech to disable the third click.

EDIT: You also need to match the radius of the front mech to the size of chainring it's to be used with. Ie mountainbike front mech designed for use with 42/32/22 chainset is going to be too tightly radiused to work with a 53/39 road chainset.

EDIT #2: I have had issues getting triple front mechs to shift on double chainsets. It should work but I've found triple mechs often have wider cages than doubles and so don't pick up the chain as well.

Thse things may or may not affect you, I haven't read what your planning to do properly.

cable pull is definitely different on the road front mechs - the reach and lever action is just that tiny bit different

I had no idea that road and mtb could be so interchangable

Not actually planning anything..............yet

Payday in a week as well :roll:

Personally I stick with bar end shifters. That way you can mix and match just about anything you can think of.

Take this as a base to start from (if it wasn't so far away I'd bid on it)

Id just be looking to put some road bars on it and the shifters that i linked to earlier as they are 3x7.

Id need to a triple road mech as legrandefromage mentioned,

Is it really that simple????

I'll take your word on the reach and lever actions - it's easy to see that they would be different, because of the different geometries - bigger jumps on road doubles etc but I still reckon that if the mech matches the chainset then it can be worked by either road or mountainbike shifters without (significant) issue.

Heck, I'm sure I'd not have to look too far to find a hybrid OTP running a combination of mtb shifters with road mechs.

Those are road specific flatbar shifters - just to muddy the waters a bit more... :facepalm: :mrgreen:

After much thought I've decided I'm going to stick some drop bars on my diamondback ascent.

Got to get a house move out of the way first and then it's game on.
