road derailleur on an mtb

[Tumbleweed]

ok, so some of the pros opt for a two-ring crankset and front derailleur. what shifters do they use. are mtb shifters compatible? how does it work? 

[AndreZA]

you only use use the first and second clicks on the lever. The derailleur limiter will stop you from clicking onto the 3rd missing ring.

that simple? thanks, para.

[ViperSquad]

Theoretically you could use the same shifters,  adjust the screws on the FD so that it does not move past the last chainring, thereby resticting it to only one click up or down.

There are guys who use road FD's to save weight. AFAIK they're the same ratio as MTB ones.

Or just adjust the cable and run it really short, so the derailleur cant move the chain lower than the middle ring. Thats how mine was set up 

[GoLefty!!]

is your 2 ring set up a dedicated 94mm 5 arm BCD or is it a 64mm, 4 arm BCD?

 

If its a 94mm 5 arm then the spacing between the rings is a little closer and a conventional trigger shifter will have some difficulty delivering reliable shifts. A gripshifter works best with this set up.

 

for a 3 ring 4 arm chainset, with the granny removed, a conventional trigger can be used.

I have a road d?railleur on my MTB - but I ride a triple.

Mine was a traditional 3 ring crankset with granny removed, shifting with a trigger.

Hehehe in the Sani2C I asked Paul Cordes what 2 blades was like. He replied, 'When I'm feeling power, it's awesome...'

 

'But when I'm not, it's not!'
