I tried the spray lube and everything else that's recommended for stuck shifters. Nothing worked at all. I took it into my bike shop and they checked, then agreed with my assessment. There are no new DA 7800 series shifters available anywhere and DA isn't repairable like Ultegra or 105. Rather than buying a used one that's going to fail, I want to go to something new, even if it's a pair of NOS Ultegra 10-speed or 105 10-speed.
Front Left Shimano Shifter Freezing?
just got my bike redone with new housing and cables a few weeks ago at my LBS.. and ive been seeing some problems...
SHIMANO ULTEGRA 10 shifters... sometimes my left shifter freezes up and i cant shift from my big to small chain ring.. when i press the lever in... it wont click feels... like its stuck... when i apply firm pressure it feels like ill break it... then i dont know how.. but later on i get it un-stuck and it will shift up and down fine... seems hard to replicate... as it is right now its stuck again... and i will leave it alone until i fix it.
one of the LBS mechanics checked the derailleur cables seem fine... said it could be something with the shifters but told me to come back later to see another tech who could better help me out with it...
just wanna come here and ask the forum and if anyone knows anything that i could have possibly overlooked please let me know.. :idea:

Ultegra and 105 are not repairable either. Shimano doesn't make any modern shifter that's 'serviceable'.I tried the spray lube and everything else that's recommended for stuck shifters.

Are there any shifters available that properly operate a Shimano 10-speed cassette? That's what I'm looking for. I don't care if I can get them serviced at a later date; I may buy an extra front shifter as a spare.Ultegra and 105 are not repairable either.

I would rather not have to change out all the rest of the running gear. The rear hub is splined for Shimano and the wheels are no-longer-made Cane Creek 23C road wheels with Ti spokes.
The first thing I would do is try a different bike shop. I have a friend who had a jammed shifter and she visited one shop who told her the shifter was shot and needed to be replaced. They didn't have the part, so she visited another shop. This shop found pieces of frayed cable that caused it to jam. He got the pieces out, changed the cable and had her back on the road.Are there any shifters available that properly operate a Shimano 10-speed cassette? That's what I'm looking for.

If it's just the front shifter and it really is shot, then just replace the front. Any 5600/6600/7800 or 5700/6700/7900 generation Shimano front shifter will work with your existing derailleur. You may even find some new/old stock on eBay, so check there.
If you can't find that, the 5800/6800/9000 generation and newer will require a new derailleur since the pull ratios are different. But front derailleurs are cheap.
These are offered as Shimano compatible.

@velodog this looks like it will solve my problem! I'll order a set and get my shop to do the installation. I will also provide an assessment in this thread when the whole debacle is finished and I can (warmly) ride here in Vancouver.These are offered as Shimano compatible.

@velodog I bought the shifters and had a good bike shop install them and put on new bar tape. The rear shifts about as well as the old DA 7800. The front shifts perfectly as long as I don't try to shift under any sort of load. The old setup wasn't a huge amount better so I'm happy. I just plan ahead or pedal really hard and shift when decelerating slightly with no chain tension to speak of.
The hoods feel good, the shift feels good but the brake levers aren't pushed to the side during shifts - there's a long button in the hood that you push. Shifting effort isn't high.

I mean, why accept shifting F ups? My SRAM and Shimano 9000 are perfect? I shift however I want? Whenever I want? Under whatever load I want?I'm glad they worked out for you.
Good for you; your bike is probably quite new and runs about a 53-39 crankset.I mean, why accept shifting F ups? My SRAM and Shimano 9000 are perfect? I shift however I want? Whenever I want? Under whatever load I want?
The problem I dealt with was going to new shifters that worked with my existing 10 speed rear derailleur and cassette. I didn't want to go ahead and change everything out to 11 speed.
The front shifter has always been slightly problematic because I have a 50-34 crankset and a braze-on front derailleur mount. The braze-on mount makes it impossible to get the derailleur down to the ideal height for the smaller crankset.
IRD Front Derailleur Dropper | Interloc Racing may work, or it may drop the derailleur too far fouling the chainrings, but it may be worth considering. They don't say how much drop it provides but they may respond to an e-mail with any questions.Good for you; your bike is probably quite new and runs about a 53-39 crankset.

@velodog I'll order one and give it a try - many thanks for the suggestion!
I put a 50/34 Dura Ace 9000 group on my last build two years ago. It works flawlessly. I learned a LONG time ago not to throw good money at bad ideas. It’s your build, do as you see fit. Piss $40.00 down the drain here... Then maybe another X dollar waste with shitty performance to show for it. Garbage in garbage out right? Putting crappy ill matched components on your bike will yield results like you are seeing. That’s cool, it’s not my business, but you need to accept the failure and the poor planning. You want to hack some kind of upgrade or change on the cheap then you get what you get, a drivetrain that doesn’t work. Good luck bro! Keep lighting $20.00 bills on fire and complaining that things don’t work.Good for you; your bike is probably quite new and runs about a 53-39 crankset.

@PBL450 I think you're missing the point. I'm working with a 15+ year old bike and want to keep using it. I'm not going to buy a new bike and all the associated components for thousands of dollars so I can keep doing what is now casual riding. I'm glad you were able to build a bike that suits you and your current riding style. From your comments in this thread I somehow doubt that you will have that same bike in a decade and a half, especially with almost all the same components.
I hope it works. I’ll have this build for a very long time. It was made for that.@PBL450 I think you're missing the point. I'm working with a 15+ year old bike and want to keep using it.

From what you've described, it does seem like the problem could be with the shifters themselves. Sometimes, small parts can get jammed or stuck, which can cause issues with shifting. It's good that you're planning to see another technician who can take a closer look and hopefully provide a solution.just got my bike redone with new housing and cables a few weeks ago at my LBS.. and ive been seeing some problems...

In the meantime, it's best to avoid using the shifter until it's fixed. Applying too much pressure or force could potentially damage the shifter and make the problem worse. It's also a good idea to check if there's anything else that could be causing the issue, such as dirt or debris that may be interfering with the mechanism.
Overall, it's always a good idea to seek the advice of experienced technicians when you're facing any issues with your bike. They have the knowledge and tools to diagnose and fix problems, and they can provide valuable insights and recommendations to help you get the most out of your bike.
Mine's been a lot like that since it was brand new, 10 years ago.

105 FD shifter sticks, doesn't shift?
Hey all, my new, brand new 105 FD lever has a little tab (actuated by the downshift lever) that sticks outward some of the time after going into the large ring. When this happens, it doesn't shift out of the large ring, in fact, the lever isn't pulling any cable, so it doesn't shift. Pushing...
