convert grip shift to trigger shift

Is this as simple as just swapping out the shifters and hooking up the cables? The current shifters are labeled Gripshift 2 MRX 170-11 SRAM. The derailers just say Shimano on them.

No problem at all. There's even 2 ways of doing it.

The "A" answer is to acquire a Shimano shifter with the proper number of speeds either attached to a new brake lever or buy separate replacement brake levers (my personal choice). Besides replacing the cables and housings (which will come with new in the box parts), you'll also need a set of new, properly sized handgrips too.

The "B" answer is to carefully cut the shifter away from the existing brake lever and replace just the shifter. That'll save you around $25.00 if you have to pay full retail for the parts.

If you happen to find a trashed bike that has the "right" shifter parts on it, take $1.00 of the money you just saved and buy a lottery ticket immediately because this is your lucky day.

Ah, I just did this on my old Specialized HR & had to swap out the rear derailier to shimano as well. No big deal . For 40 bucks I bought regular grips & an Alivio (sp?) rear derailer. Now, it shifts great. The pull rate / ratio on (at least some) sram components is different from shimano.

MRX are 2 to 1, so are the Shimano deraileurs. Just be sure to get triggers that say 2 to 1 or Shimano compatable.

How many speeds? I have a Shimano 2:1, 7-speed trigger/brake set-up I'd love to swap for grips. That's all I ride.

Be sure you guys swap the grips as well as the shifters and levers. The grip shift grips are shorter than regular hand grips.

If you can't work out the swap then look around and find just the shift pods. With the pods without levers and new grips you just swap the grips and shifters and don't touch the levers.

Thanks BCRider. The reason for the conversion is because I am putting trekking bars on. The grip shifters and brakes levers are separate components by the way. I am watching some shifter on ebay right now. I cannot send HPS a pm because of my post count.

It looks like you don't have enough posts to send PMs either. I have a set of older 3x7 grip shifters compatible with Shimano derailers. Send me an e-mail at fastjake54901 at yahoo dot com if you'd like to do some sort of trade. I can't stand the grip shifters

Yes they will work for you. Not hard to do the switch.
