Friction shifter type which is better, lever or twist?

which is better for precise trimming, and more reliable in holding the cable?, shimano indexed twistgrip is severely rated, but when twisting without index but only in small interval, would twist gain more advantage in precision and since the lever especially of metal has a certain momentum due to its weight which may bring it off the position, such as in a sudden braking situation, but plastic twist grip is very light and momentumless compared to lever, doe s this make more sense in holding cable in postion?

Thanks!

The only place for twist shifters is in th garbage can.

I much prefer lever style shifters of some kind to twist shifters. I have friends who hold the opposite opinion.

I've got to tell you - the effect of momentum while moving the shifter doesn't enter into my thinking one iota.

A purely friction twist shifter would be very poor at precisely trimming position because your hand's constantly on the mechanism. As your hand moves, so will the shifter and derailleur. Hit a bump? Oops, I shifted. A twist shifter placed somewhere your hand doesn't rest, like the road bike Gripshift shifters from the '80s, would be immune to that problem, but they wouldn't be any more or less 'stable' than friction levers.

As for the relative lightness of materials, since you brought it up... Most levers are metal, but they're lightweight. And most of the metal is near the axis, so the rotational inertia is very small. It's insignificant compared to the friction of the mechanism. I've never had a problem with friction shifters slipping due to the mass of the lever.

Have never really been a fan of twisters. All my bikes are and have been some sort of lever.

It's much easier to service levers. And twist shifters don't fit on the downtube.

If you have upright bars I would recommend you buy t set of Sun Race friction Thumbies. The ones with the red face.

https://www.niagaracycle.com/categor...SABEgK9WvD_BwE

They work fine and are inexpensive.

Suntour made some of the best friction shifters. Their power ratchet style are especially good. They made downtube, stem, and thumbie models and I have used them all . They are relatively easy to disassemble and clean and will probably outlast your present and any future bikes.

Combine them with a close ratio Shimano hyperglide freewheel and new chain and your bike will shift slicker than snot.

I'm a Gripshift fan, myself. Not fond of Shimano twisters (like Revoshift).

Are we talking about Front Derailleur usage here, with the mention of trim?

My favorite is the Sram Attack Gripshift, unfortunately there are only right shifters up on eBay at the moment. They're very solid and have 9 positions on the left shifter. Also have Sram 3.0 and MRX. Those also work well, but feel kinda flimsy compared to the Attack.

I haven't tried the newer 10 and 11 speed pairs, but the build quality looks very nice.

My favorite "friction" shifter levers are ratcheted. Suntour Power ratchets are pretty sweet.

Been a friction lever lover for the past 50 years. Friction is all I've ever had. I like the infinite adjustability--fine tuning, if you will, because no matter what gear I'm in I can fine tune the dr's and ride noise free.
