SRAM Force eTap AXS FD chain drop

Road Cycling ďIt is by riding a bicycle that you learn the contours of a country best, since you have to sweat up the hills and coast down them. Thus you remember them as they actually are, while in a motor car only a high hill impresses you, and you have no such accurate remembrance of country you have driven through as you gain by riding a bicycle.Ē -- Ernest Hemingway

SRAM Force eTap AXS FD chain drop

Sooo.... I'm wondering when I can expect this to start happening on my new bike? Everything I've read on the internet strongly suggests that SRAM eTap AXS front mechs are garbage, guaranteed to drop the chain on every ride. Now it's very early days for me, but it's not happening yet. Front shifting is actually very smooth both up and down. Not even the slightest hint of throwing the chain off in either direction. Am I being lulled into a false sense of security or is it just the usual internet amplification of problems? Or have SRAM sorted out previous issues through hardware or firmware tweaks? So far I'm impressed with it. It's not even noisy like they are supposed to be!

I have never dropped a chain with SRAM AXS FD using 53-39 crank. Very rarely dropped with 11 Speed eTap but I was also shifting 56 down to a 39 with a very old crank. The 10 year old mechanical 11 speed SRAM FD was less good for sure.

My AXS upright bike is currently 1 X with 48T and no problems.

This one is a 48-35 chainset

That should be less a challenge. I noted my chainrings to show even using non-recommended rings, the AXS and eTap handled it.

I still have the old mechanical 11 speed on two bikes, the FD is just ok. The newer ones are better. I was using barcon to shift a Shimano ultegra in place of the old SRAM FD at one point but eventually just lived with just fair front FD shifting, the newer stuff is def much better. Is it as good as Shimano? I do not know

I haven't ridden with Di2, so can't make that direct comparison. But the front shifting is smoother and probably quicker than mechanical Shimano 11-speed. I don't see how it could get any better to be honest within the mechanical limitations of pushing a chain across 2 chainrings. Rear shifting is slick too. Everything I expected from electronic shifting. I was just a bit nervous about SRAM road groups, even though I've been using their 1x mtb mechanical group sets for years. Just the internet talk spooked me a bit!

I’m running 48/35 SRAM under the Force AXS Wide FD on my rig and have never had chain drop. I guess with the proliferation of 1x, I should add that I actually use the thing, too. I can clean a lot of my local terrain with the 10-33 cassette x 48t, but there are definitely some climbs that go by better in the 35t, so yeah, I shift gears.

The most common problem is improper FD setup. It's easy to set the alignment marks parallel to the big ring, then fail to notice that the FD rotated a bit when the clamp bolt was fully tightened. Sram shifting ramps may not be the best either. I check the space between the FD cage and crankarm accurately, before and after tightening the clamp bolt.

I have the same setup as well as two bikes with mechanical 10 speed - one Red, one Force. I must have deficient sensors, but all of my Sram FD's have always shifted perfectly. My Shimano mechanical FDs have always done the same too. Shift the button or lever, and before you can say "uh" it shifts and doesn't drop.

Between my wife's bike and mine, we've ridden probably 2,000 miles and no problems. So my guess is that OP will experience the issue exactly on...never.

That AXS FD is easier to set up than most: the marks on the FD cage greatly assist in alignment IMHO. I tried the plastic installation jig, but found it was easier to do it the old way of setting the alignment (with the marks) and the clearance with some sort of feeler, or even eyeball.

I do like the Force Etap AXS Wide HRD group. It was a splurge for this Senior Citizen thinking "if not now, when?" and it's fun. Comfortable hoods, easy installation, lots of lever adjustment available. Not enough to swap over my other bikes because they're perfect too.

In all my years, Iíve never had FD troubles with any of my other kit either, be it Shimano, Campagnolo, or Suntour, road or MTB, so like you, I donít get all the consternation over FDs, and tend to think the whole thing is a ďfalse flagĒ issue; 1x people try to blame FDs to disguise their own inability to understand and operate a 2x drivetrain, maybe. I dunno, I donít get it. For road riding, really, I donít get it, but all thatís another discussion.

The interesting thing about my Wide FD setup is that Iím not using the Wide crankset, but it still works fine. I think maybe itís not as fast as it would be in a properly matched system, probably because of the longer derailleur throw, but itĒs one touch effortless, so itís nice.

So it looks like I don't need to worry too much then. After reading a few SRAM AXS horror stories (especially Force) I honestly thought it was going to be a pain to set up and that chain drop was almost inevitable, lol. I now get the impression issues are blown out of proportion and then fuelled by Shimano diehards. Can't say I"ve had any issues with either brand over the years. My other road bike has 105 R7000 and that works flawlessly too. My last 2 mtbs had mechanical SRAM X01, which has been great too. I have to say my first impression of electronic shifting is excellent. Even better than I expected.

Now I just need to get past Thursday pm....

Yes I thought so too. Mine was factory built by Canyon and alignment was spot on when I checked. Only fine adjustment I made was to close down the chain gaps on both sides of the front cage to the 0.5 mm limit as recommended by SRAM. Shifting was perfect in the stand and on my first 25 km road test. Didn't need to trim the rear mech either. So far so good.

Was it ever a real issue? Did something change along the way? Genuine questions btw.

Yea, same here. The limits are set like any other FD, so I just can't see there's anything special about avoiding chain drop. That said, I do have a chain catcher on my carbon fiber frame - but it came integral to the FD. I have no shame using a chain catcher on a CF frame even though I fancy myself an excellent FD adjuster. I don't do it on a metal frame though.

Yeah, I did fit a chain catcher as a precaution. First time I've ever used one, but seems like a good idea. I have had the odd chain drop on other bikes. It happened once last year when I downshifted coming way too fast into the base of a sudden steep climb, so I'm sure it will be of use at some point.

Iíve had significant trouble with sram force axs chain drop. It happens randomly. I have had it set up by three different mechanics. We have shorted the chain, set the limits very tight and I have a chain catcher. The only solution seems to be to upgrade the force front chain ring to a red front chain ring ( interestingly the new sram force front chain ring is one piece of metal just like the red front chain ring) seems like there is too much flex in the original force chainring and it sometimes throws the chain off

Why would a Red chain ring help chain drop. Sounds like someone is trying to get your money because he/she can't properly adjust a FD.

i donít think itís inability to adjust the FD. Three different mechanics have done mine from different shops. Two other guys I ride with that have sram force axs and use different mechanics to mine also have chain drop issues. If itís that hard for bike shops to set up then itís a bad product. I think itís the chain ring as sram just brought out the next generation of force and it no longer has a two piece front chain ring. It now has a one piece front chain ring just like the red front chain ring. It has been a maddening problem for me for two years.

Are you shifting the front under heavy load? Is it dropping when shifting to big or small ring? I've been using Force AXS for 18 months now and it has dropped the chain 3 times when shifting to the big ring under very low load. It has never dropped a chain going to the small ring, which happens occasionally on my other bike with Shimano. At the moderate load I typically shift the front I can't see flex being an issue.

This is why SRAM vigorously advocates for 1X drivetrains.

Thankfully, they don't take a similar approach with their brakes.
