Do Shimano Claris integrated shifters retain the trim function?

Long time since I've posted here. I was tempted to post in the Road Cycling forum as those guys should know but then I read a few threads and reminded myself why I like this forum so much more

So, simple question as detailed in the subject. A friend is considering ordering a bike with Claris or the new Sora 3500 group. I know the latter has trim but Shimano hasn't updated their tech docs for the new Claris group. Lack of trim would be a real good reason to spend a little more on a Sora bike but there are other reasons he'd prefer the Claris bike.

Thanks in advance.

Go test ride the Bikes at the Dealers .. see for yourself.

Shimano Brifters AFAIK Dont trim the FD, they just throw it into one place

and let the cage shape not drag the chain too much on the cage

as long as you stay away from the cross chain Combinations.


My derailleur bikes all have Bar-end Shifters or Thumb shifters.

they trim, when you move the lever to clear the chain after the shift.

In slight contrast, AFAIK all recent (going back to say early 2000) Shimano brifters DO trim the FD though some have more capability than others. This PDF from Shimano's site highlights some of the differences but is quite out-of-date: http://bike.shimano.com/publish/cont...20Function.pdf

i'm running 105 brifters(ST1055) on a 105(1050) drivetrain from 87. since my original levers were DT i had friction on my FD. i still have some trim available to me on my brifter for the FD, but not for the RD. My brifters are early iteration 105, so that may make a difference.

if you're upgrading an early drivetrain with a newer component the trim may be available, but only if your derailleurs already had trim/friction shifting. i don't think an entry level group will have it, but i could be wrong.

I might not have been clear enough in my original post. I'm looking at two brand new, fully built bikes. One has Sora 3500, the other Claris. Both are the dual paddle style of shifter. All versions of Sora that I've used (3300 and 3400) have had trim so I believe there's a chance that Claris has it. I recall reading though that the previous entry level Shimano integrated shifters (2200 and 2300 I believe there were called) didn't have trim. I don't want my friend to be disappointed buying a bike without trim but he prefers the Claris bike to the Sora bike for other reasons (otherwise I'd just have him buy the Sora bike).

Anyone with a definitive answer?

See above. The question is regarding Claris, not Sora.

First I've heard of "Claris". Where is it supposed to land in the hierarchy? Googling a little bit, seems to create a new hierarchy for commuter/hybrid/comfort.

I was responding to post # 2 by fietbob . as far I know "Claris " is fond on the hybrid/comfort bike, as where Sona are on road bikes .

It's positioned below Sora and seems to be aimed at the entry level drop-bar and flat-bar road market, hence the two different shifter designs. Since Shimano moved Sora to 9 speed, 8-speed Claris is an easy way to still utilize tooling for lots of 8 speed components in the road market (chains, cassettes, cranks, front deraillers).

The Claris group offers integrated road shifters (aka brifters) with the now-standard dual paddle arrangement as opposed to the thumb-button style of the old Sora/2200 groups. The only outstanding difference between Sora and Claris is 9 vs. 8 speeds respectively. If you dig deeper, you find that the Claris rear derailler is designed to work with a 32 tooth max rear cassette cog (vs. 28 teeth for Sora) which allows the group to more easily move between comfort/hybrid and road bikes.

Claris is the new name for 2300, IIRC. It drops the thumb lever for a lever matching the higher end groups. Shimano hasn't put it on their website yet, it seems.

As a follow up to a previous post, I looked up the tech doc for the old 2200 group and it does offer a trim function for the inner chainring. Based on that, I'm going to assume for now that Claris at least offers that trim function which is good enough AFAIC.

If someone can please post a definitive yes/no on the issue I'd appreciate the added peace of mind.

Here's the beginning of the tech document section on Claris: http://techdocs.shimano.com/techdocs...&bmUID=j_zFm2u

the claris is really the 2400. it's taking over for the 2300 which is entry level, AFAIK. so, the last sentence of my statement applies. sora is a step up over tiagra which, in turn, is a step up from the 2300. there's really only one way to find out. ride the bike.

I'm not sure what of the above you feel is relevant/new information for me. I'm well aware of where Claris stands (you did misstate in the quote above that Sora is above Tiagra though when it's really the reverse).

Regarding your initial post, you also make a misstatement when you say, "if you're upgrading an early drivetrain with a newer component the trim may be available, but only if your derailleurs already had trim/friction shifting". The trim function is built into the shifters, not the derailleurs. I could take a down tube friction shifter bike, not change anything but the shifters, and I'd have any trim capability available with the newly installed shifters. I would not have infinite trim like the down tube shifters though. Nor would I get any more trim functionality by using Claris shifters with 8 speed Ultegra derailleurs or some other such mix of components.

Apparently this isn't as simple a question as I initially thought. I was hoping to find someone with actual experience with Claris installed on a bike. I guess it's all moot anyway though as my friend ordered the bike based on my fairly good confidence that Shimano would not have removed the trim function from the 2200/2300 series shifters. I'll update this thread when the bike arrives and I've had a chance to test it out.

I think he's just answering my question; I had never heard of Claris before.

Possibly, but he quoted me and referred to his prior post which was also addressed to me. He's new here so maybe he's just finding his groove

For anyone wondering, the Claris shifters do have the trim function and can even trim all three chain rings, unlike my Ultegra 6503 shifters! Not bad for the money.

I doubt that Claris will trim all three rings any better than your 6503 shifters. As I'm sure you know, the 6500 (6503) shifters have 4 "main" positions plus a soft click trim for the smallest chainring. In essence this means that you have 2 positions for each chainring for trimming. Normally when on the big chainring you would use only the 4th position, but you can use the 3rd position for trimming toward the inside. The 2nd and 3rd positions are for the middle chainring.

Maybe I need to adjust my setup which otherwise shifts fine but I do not have a usable trim position for the big ring. Even the Shimano tech doc linked to above shows no trim position for the big ring. Is there anything special you did to make what is essentially the middle ring "outer" position work when on the big ring? As soon as I shift down to that with my setup, the chain is on the middle ring.

I think what you are experiencing is normal function for your shifters. If the chain is running on the big ring and on most cassette cogs it should drop to the middle ring with only one click. Depending on the length of the chain stays and chain angle, some riders find they can use the 3rd position (outside middle ring position) to trim the front derailleur when running big to big or big to next to big (not recommended). There should be no reason to trim to the outside.
