Converting 9 speed Ultegra Brifter to 10 speed

I have a 15 year old Trek 5200 with US Postal livery which I use for touring. But, the 9 speed Ultegra brifter (right hand one) has finally died and there are no reliable replacement units available. I plan to replace the brifters with 10 speed Shimano Ultegra brifters. I know I'll need to change the rear cluster to one with 10 speed spacing, but do I need to change the derailleurs as well? What about the front sprockets and brakes? Any insight would be appreciated.

New 10-speed cassette and chain are needed. Everything else should be fine.

You might be able to bring the brifter back to life with copious lubrication.

Did you try hosing/soaking your malfunctioning brifter out with PB Blaster to blow out/remove the old/deteriorated grease?

Have you looked/been looking on eBay for a new Ultegra 9 brifter OR for new replacement parts to repair your brifter?

Have you checked your local bike shops for a leftover new old stock Ultegra brifter?

Have you checked at your local bike shop to see if the part/s to repair your malfunctioning brifter are available from Shimano?

Nine speed Microshift.

Shimano does not sell repair parts for their nine speed STI.

You are running a Domane 5.2? Nice. It's on my 2017 wish list.

Can you describe the symptoms of the shifter failure?

Nashbar has a 9spd brifter set for $130 (Nashbar N-9 9-Speed Dual Control Shifters) > If your chainset is the original
and is 15 yrs old , you may find you need new chainrings as well if you go the 10spd route with new cassette and chain. I agree otherwise, 9spd chainset
and deraillers work fine on 10spd. I did the same swap out two yrs ago when a dog knockdown trashed my R 9spd brifter. FWIW I have a NOS
ultegra 10spd brifter set with cables for $100. I had a low opinion of Shimano brifters in 8 and 9 spd in the 2000-2009 time frame so bought several for
use on tandem and two frames but the brifters seem better now and are lasting longer. You got a very good life span out of yours if they are 15 yrs old
Usual "failures" that are fixable are a frayed cable inside the brifter and failure of the lube or dirt in lube, hence the advice to rinse it out thoroly with
mineral spirits and relube with heavy oil. Shimano lightly greases the innards, but they are relatively inaccessible for anything not liquid. Brifters are not
easy to take apart, but require watch maker skill sets to put back together and there are NO user serviceable parts inside. There are youtube videos on
how to do this, but it would be stupid.

Any chance these are 6700 with concealed cable routing? Very interested if this is the case!

No, these are all early 10spd stuff, two 105s and one Ultegra all with exposed cables. Damn Nashbar had some really low prices on these (>2x what I asked)
6-7 yrs ago and I ended up with a Campy centaur 10spd, used ultegra 10spd (take-off of mine when I did a Di2 switch) and the NOS mentioned. My Teledyne
Titan will get a 10spd upgrade when the current 9spd cassette wears out from one of these.
