FSA Gossamer compact and 105 problems

Road Cycling “It 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.” -- Ernest Hemingway

FSA Gossamer compact and 105 problems

I have searched around a bit and haven't found any accounts of problems to the degree that I'm running into with my wife's Ruby Comp with the Gossamer compact paired with 10 speed 105 drivetrain. Ever since the bike was new the dérailleur has had a hard time making the upshift to the 50 ring. The bike was bought and tuned at my preferred LBS in the area, and worked well enough to 'get used to,' but nowhere near my standard double ultegra F/D shifting quality, which I don't expect it to. I would estimate that she's put around 500 miles on the bike since new, and she's most definitely a spinner rather than a masher. From the very beginning I taught her to ease the pedal force while shifting, even r/d shifts.

More recently the problem has increased and expanded. Not only will it not shift up unless you've released ALL forward force to the pedals, but once in the big ring, shifting back down will often catch the chain between the rings....resulting in the terrible sound of medal scraping on medal for a couple revolutions before realization sets in that she's not going forward. I might add that these conditions are VERY consistent. This problem has continued directly following a tuneup at my LBS, which has been nothing but helpful so far. I'm not writing to simply moan about quality of this setup or the shop's mechanics. I'm just curious about compatibility of parts. I'll say this.

-I do expect an expensive and very new bike to shift consistently in both directions (smoothness asside)
-I do expect brifters to be adjustable so that 'trim' settings can be used when slightly crossed over (this is
sadly a necessary reality with compact cranks as the middle gearing is largely in the crossed-up range)
-I do NOT expect shimano 105 to shift as seamlessly as Ultegra, or even to be as quick at shifting as my
standard double.

My question I guess is about the the design/functional issues with the shimano 105 10 speed stuff (being that they use the same shifter for both double and triple cranks), and especially it's ability to shift between such a steep difference in gearing as a compact. I tend to think that these parts MUST be compatible as this setup is used on MANY bikes by different makers, but I simply can't imagine cyclists dealing with such a poorly shifting bike.

I need to know if smooth shifting is possible with this current setup or if I need to seriously consider unloading this stuff now while it's still young and upgrading to something that will work. My wife loves to ride, but this shifting thing is an inconvenience that nobody should have to accept as standard. I'd love to hear about your experience with this stuff. Thanks for your time, and I'm sorry this ended up as a short essay.

-Jeremy

Assuming your LBS has checked the FD alignment, I would swap out the crankset (temporarily) to see if that is where the problem lies. It sounds like an axle length or spacing issue with the crank.

If your LBS is a good one (and you bought a bike there, ANY bike) they should be willing to help you with this is you can't do it yourself.

I have the same combo on my bike, and while I constantly find myself fiddling with the FD adjustment, I do not have the problem to the extent that you are describing. My problem is that the FD doesn't like to hold its adjustment and starts to rub sooner than later, which I find to be pretty peculiar... I am planning on upgrading to Ultegra cranks / FD pretty soon myself.

small to big chainring shifts have dramatically improved after losing my fsa goss and switching to Chorus...also, over shifts and chain drops have never happened since. Not saying its all the goss's fault, maybe it was setting, maybe it was bad luck...just saying.

My LBS insists that Shimano works best with Shimano.
Not that it is a correct line of thought,
but it seems to be showing some truth to it.

I've been running FSA front cranks with a 105 FD for a few years. I've found that for smooth shifting, you need to set the stops a little bit outside of where you normally would set them.

As for trim, I haven't really found a need for it. In a pinch, I suppose you could put on some Jagwire inline adjuster barrels. But really, the chain dropping and getting hung up in between rings on up-shift can only be attributed to cross-chaining. If you must, at least put a couple extra links in the chain to give the derailleur a break.

My FSA compact (36/50) and 105 FD don't always get along either. After locking up the cranks a couple of times trying to get into the 50, I took it to the shop. I got no help from my LBS on the adjustment front. Everything seemed fine. Adjusting the FD made things worse--couldn't get into the 50 at all, always dropping the chain going back to the small ring, etc. I've found that shifting from approx the 4th cog up in the back and keeping the chain a little on the wet side yields the best results (I used to use Rock N Roll Gold lube, but it has a drier feel. Now, even if I use that to clean, I'll relube with Prolink and leave it a little bit extra-oily feeling). Still, I have to be sure to soft pedal when shifting up. It's such a pain, but it's not worth spending a lot of $$ changing everything. FSA recommends using one of their compact FDs, but the LBS says it's not necessary and they're just trying to sell me stuff I don't need.

As for cross-chaining, the 105 FD will have a half-shift in between changing rings that will eliminate some cross-chain rubbing. My lever gets sticky, so it's hard for me to do this when I'm in the big ring, but it's easy to shift over slightly in the small ring when using smaller cogs.

I have a FSA f/d with the gossamer cranks (105 shifters) and have nothing but problems. So there goes that recommendation

I had many of the problems listed above - overshifting, dropping chain on downshift - and after 3 different mechanics, the best any of them could do was to keep the chain falling off at the cost of not being able to upshift unless i am in the smallest 3-4 cogs. Any bigger than that in the back, and the f/d won't push the chain up.

I too am so tired of this setup, and as a result have come to hate riding my bike. I am tired of looking like this when I ride: I can't wait for spring to get a new ride when I have saved up the money.

Sorry I couldn't add any insight to help the op's problem, mainly because I never got an answer myself. Just wanted to let him know that it seems to be a fairly common occurrence, based on what I have read and heard. I know I am never going anything less then ultegra again, and based on my experience with compacts, probably not going that route again either.

Why hate your bike when you can swap the crank/fd and be happy?

I have FSA Gossamer and 105. I had to switch to FSA pro chainrings and a wipperman chain to fix my FD problems. There was just too much flex.

The problem isn't 105, it's FSA. They cut corners while trying to design a light, inexpensive crankset. Oh, and it's not light, so it's even more useless.

I have a compact FSA SLK Carbon crank w/ 105 for a FD, and have had no issues from day 1 to just over 1000 miles this year. Actually find the shifting pretty crisp going up to the 50, but I will admit that the trim 'click' adjustment isn't alway spot on.

I picked the bike up for a steal just wanting to try out road cycling. I don't want to put any more money into it than I have to. It was my plan from day one to get something carbon with higher end components in the spring if I enjoyed it, which I do. I would rather put the couple hundo towards something new.

I have the FSA Gossamer and Ultegra FD and it shifts like butter; no complaints after 4000 miles. I'd try a different derailleur or a different LBS.

I have 1000miles now on my FSA Gossamer Compact w/Ultegra FD, and never have had to adjust it. Shifts perfect. I dropped the chain once but more cause I was ******** and shifting durning a 10% hill from big ring to small ring mid stroke pushing 600watts, but like I said I was ******** for doing that

I have an FSA Carbon Pro Compact with a 105 FD 10-speed setup and have had none of the problems you describe. In 1000 miles I have never had to fiddle with the FD.

Hey thanks everyone for your input. Seems like these problems aren't terribly uncommon, even to the same degree as mine.

I just spoke with my LBS again and let them know that the problem persisted even after their tune up. He mentioned similar problems primarily with tandem bikes running FSA cranks and that they've had success with simply replacing chainrings. A possibility at least to think about. He told me that he'll be on the phone with FSA this afternoon regarding this issue and see what they'll be willing to do to address this issue. With any luck we'll find a solution and have her back on the bike smiling. I definitely won't be advising anyone considering a compact crank to look at these ones though. I've read no negative reviews of the Shimano compact cranks, so it seems that there is some critical design difference that FSA needs to address. I'd thought getting the chain caught between the two rings was a problem of yester-year. But apparently not. Thanks again for your input, and I'll update when a solution is reached.

-Jeremy

I'm not sure about 105, but for Campy, there are specific front deraileurs designed for compacts and the issue of ramping up to the 50t ring from 34 or 36t. My Chorus CT FDR works flawlessly.
Shimano has been slow and half-assed when it comes to compact.

However, the OEM Gossamer 50t chainrings are total sh8t. They are under-engineered and flex sideways too easily.
Replace the 50t chainring with the super road ring -these are like DA rings and are much stiffer.
This is what CSC did for TDF. FSA is all over the place with their chainrings on the different cranks, but the expensive cranks use better chainrings.
Why? Because the dirty truth is that a Gossamer crank only weighs 30g more than a CF crank at a fraction of the price -more profit in CF cranks.

I would have to say it's a FSA issue and not so much the 105. I have FSA K Force Carbon Compact on my current bike with Ultegra FD and have had some issues with it as well, not to the extent of the OP. My previous bike had the Shimano compact and I never had any issue with it, not even a dropped chain. If I would have realized this from the get go I would have had them swap out the cranks on delivery but now I just let them adjust it as needed...

My wife's Serotta came with a Gossamer compact and no one could get that thing to shift either.

I finally swapped it for a Shimano R700 compact and not a problem since. The LBS tells me that they have nothing but problems with the Gossamers, and they won't spec them anymore.

Good luck with yours.

I wonder if its just the 50t compact. My Gossamer compact has a 46/36 combo and it shifts perfectly with my old timey D/A 7400 series FD. I do my own wrenching, so i may be more inclinded to make sure its absolutely perfect. I should probably mention all my bikes are set up with ISIS cranks.

Doc - I seriously doubt the diff is 1 oz. Having held my 53/39 K-Force carbon crank in one hand and my 46/36 Gossamer alloy compact crank in the other, i can tell you the weight difference is much much more than 1 oz.

I'm comparing my SLK with my Gossamer, I weighed both, neither weights were the same as published, but the difference was something like 34g. I know the K-force is lighter, it doesn't have the aluminum core. However, they are just as stiff, and the gossamer may be stiffer (stiffer than I will likely ever need to know).

Something's up with FSA, CSC used SLK cranks this year rebadged as "K-force" with k-force chainrings. Then at TDF, Cancellara was using a Gossamer with K-force chainrings. This was reported with pics in velonews.

I'd suggest the OP get the shop to try a Super Road ring, that may fix the shifting.

I have the Super Road rings on the K-force. My other bike has the older model Pro Team Issue crank with the more minimal looking rings. Truthfully, with the exception of needing to retorque alloy crank bolts, i've have no real problems with any FSA ISIS crank. Maybe they should have stuck with ISIS. Alot of what i've been reading makes me reluctant to upgrade my bikes to MegaExo cranks.

The Gossamer is a very stiff crank. A great crank that transforms my bike into a competent climbing bike for a non-climber like myself.
