How To Convert From Downtube Shifters To STI Shifters (Brifters) On Vintage Bike

I show and explain the whole conversion process as I upgrade an early 90's Trek road bike from downtube shifters and install Shimano STI shifters (brifters or integrated brake/shifters). This definitely brings new life to an old bike. The shifters I use in this upgrade are Shimano Sora 3x7 shifters. But Shimano RSX 3x7 shifters are a excellent choice also. You can find these for sale on eBay. BTW, I didn't go to higher speed shifters because that would require a new wheel with a wider axle. The rear triangle would have to be spread to accommodate the wider axle. And it's not safe to cold-bend a aluminum frame. If you have a steel frame, then spreading the rear triangle might be an option. But that goes beyond this video.
The little part I mount on to the downtube braze-on is called a downtube cable stop or braze-on cable stop or variations of that.
Here is it on Amazon:
www.amazon.com/...
or you can find them on ebay.

Amazing!!! I would just like to thank you for all of your videos. I've learnt so much from you. I've watched this video about 20 times preparing to upgrade my bike. I recently bought an old Peugeot with downtube shifters and I didn't even know how easy it was to convert it to brifters. I ordered everything, (new derailleurs, crankset, barrel adjusters, Shimano shifters etc )and I worked on my bike as I watched this. Now it's looking amazing thanks to you !!!! I could watch your videos all day. They are so clear and easy to follow. I especially love watching you solve problems. you are the best !!!

Original frame and calipers only. Everything else upgraded. Rides like a steel dream, 26 miles today and loving life. Thank you RJ! You Da Man!

This particular conversion should prove quite valuable to the enthusiast who is very fond of his current bike, but wishes to modernize it markedly with new componentry. The adaptation is both well explained and incorporates a few time-saving short cuts that facilitate a smooth conversion process without compromising the final result. The 'brifters' are a great improvement and a significant safety up-grade as well. The sequence of the changeover was impeccably logical.

thanks, nice video, that ~1974 Raleigh Grand Prix was my first bike (a 1972); I also upgraded to an aluminum rims almost right away, back in 1973. I found some minor errors 1. huret = "hurrr - eh" is the proper french pronounciation 2. when you bent the rear dropouts, I wouldn't have put the 2"-side of the 2x4" against the seat tube, on some tubes you could dent the tubing, it would have been much safer to put the 4" edge of the 2x4" against the tubing ( yes I know it's a 1.5" x 3.5" these days with lumber companies skimping on the wood.) 3. the shimano derailleur-hanger spacing (distance from the axle) is actually larger than on huret, as Shimano set the standard when they invented Shimano Index Shiftings (SIS) which is another reason why you need a shimano hanger. 4. too much cable housing on the rear derailleur, roughly 1" too much. 5. you might want to mention that new cables are BETTER than the original ones as they are (a) lined with lubricating plastic and (b) SIS cables with vertical (not spiral) winding inside so they don't stretch or compress compared to original spiral cables.

I picked up a Schwinn Paramount frame (50th Anniversary) and decided to build a bike from it for my step son. I didn't want to spread the rear triangle so I kept it at 126mm for the current 7 speed hubs. RSX Brifters for 7 speed are getting difficult to find, so I went and got Shimano Tourney 7 speed Brifters. I have RSX on one of my bicycles, but found the Tourney shifters much more better operating shifters.

Lesson to be learned here,don't fix what does not need fixing,some of these upgrades are not upgrades,they are just a more complicated way of doing things ! I despise indexed shifting ! I'm sure bike shops and Shimano loves it ! Great job on the video rj, I do enjoy watching your video's !

@RJTheBikeGuy 8 жыл бұрын

+Guy Aldrich Personally, I love indexed shifting. Old bikes would have had it if they had figured out how to do it back them. And having the shifted mounted on the bars is safer than reaching down to the downtube.

Replacement method of the inner routed cable housing is the most informative part for me. I have the Trek aluminum in the same color but the model number is 1400. I was thinking of replacing the rusty cable housing. I use a drop of Superglue at the end of the cable instead of a end cap. It looks much cleaner, glue binds the each wire together from inside(glue goes in by capillary action) and makes the cable re-usable without cutting in case it needs to be removed and re-install it. I Haven't had any problem with the method.

@RJTheBikeGuy 10 жыл бұрын

@allgoo19 10 жыл бұрын

shyflirt1 "You can get black ferrules which are cleaner looking." == Maybe it is, compare to silver ones. You are comparing to something that you've never tried. And the end cap is not reusable, you have to cut it off each time to re-use it and that sometimes means becoming too short and have to buy a while length of cable. Try Superglue just once. You'll change your mind.

@RJTheBikeGuy 10 жыл бұрын

Oh, you are talking the about the crimp ends, not the ferrules. Yeah, they can only used once. You don't have to cut them off. Just squeeze where they are crimped at 180 degree rotation and they slide right. And they are cheap. Superglue would probably work fine. I'll probably stick with the crimp ends. I have a bottle of 500 of them. they are cheap and easy.

Nice video. I have a 1990 Trek 1400 That I put some extra Ultegra 6500 9 speed parts on to convert to brifters (shifters, RD, crank). I kept the old 1055 series 105 FD because of the clamp size. It works well but the left brifter requires two full sweeps with my hand to go from the small to large chain ring. Weird. I can only guess that old FD requires more cable pull than the 6500 shifter is designed to provide. I also need to squeeze the seat-stays apart a bit when inserting the rear wheel because the wheel is 130 and the frame 126 spacing at the drop-outs.

@jeff95173 9 жыл бұрын

Tiago Augusto Santos I personally prefer to take the right cable to the left braze-on and the right cable to the left braze-on. The cable arcs are a little cleaner, and the look is a little more graceful. This does mean that the bare section of cable will need to cross under the downtube, but this is not a problem, as the contact is very light and will present virtually no friction ... certainly less than what they experience on the bottom bracket shell! It also requires that the cable stops you put on the braze-ons have to be fairly low so that the cables don't rub the downtube. This is usually the case, so probably not a problem. www.sheldonbrown.com/cables.html#routing (look for "Criss-Cross cables")
