Grip shift to Brifters.....can I do this?
Good morning all,
My son has a hand-me-down bike that has the Grip-shift system installed. I would like to know if I can convert this to a brifter system? The Grip-shift is an indexed shifting system, so I'm thinking it should not be a problem. Any comments will be helpful. Later, |
What are all the components brands, how many gears, and about another 5 or 6 questions need to be answered before your questiion can be answered. Changing to brifters often requires marching the complete drive train to the brifters. Often it is not plug and play. Roger

Good point Roger, more information needed on my part. Thanks!

Actually changing between Grip Shift and brifters (flat bar ones) is done all the time at many shops as a repair or new bike swap out. We do a number a year. First you need to understand which shifting family the bike uses (Shimano VS SRAM) then which brake lever cable pull ratio (linear pull/disk or canti/caliper). Then get the proper new parts that match and a set og grips and do the job right the first time. If you don't understand this then go to the LBS you trust to have them either sell you the correct parts and/or also do the install. This is a simple swap out for any one experienced. Andy.

Thanks Andy! His is a road bike, if that makes a difference.

As for the bike that started this thread, though, we could certainly use more info. Number of cogs front and rear would be handy to know. Even something as simple as brand, model, and rough age would help us give more educated guesses. |

If you're pretty lucky you could find some 1999-ish 3x7 Shimano RSX shifters for $40 or so. Or you could get new Microshift 3x7 for $80 https://www.universalcycles.com/shop...0&category=162 Unfortunately I think you'd have to switch to a road triple front derailleur to get the front shifting right. Maybe $25 for a road triple derailleur. You need to figure out the diameter of the seattube before shopping for those. going bigger than the seattube can be OK if you get a good shim. |

Yep. Has to be a Denali.

Could be a Denali, but not necessarily. See my post (#8) above.

Are the Gripshifts near the stem or are they on the ends of the handlebars?

The shifters are on the bar ends. I know he has a 53/39 chainring setup...
So far, you haven't given us anything that tells us this won't work. It can probably be done -- it's just a matter of what specific parts you'll need: Just shifters? Shifters and derailleurs? Shifters, derailleurs, and freewheel/cassette? |

Those are a couple of helpful pieces to the puzzle. With a little more info, like the number of cogs on the rear wheel and what brand/model the derailleurs are, we can probably tell you exactly what you need.

I would look for a complete used bike that is already set up with matching components. Save money and time in the long run.
