Finally complete: '85 Trek 720 + bonus bike
Finally finished my '85 Trek 720. Upgraded with a modern derailleur, new wheels (38mm 700cc tires), Brooks saddle, and new pedals. Also ended up having to swap out the Cinelli handlebar for a Nitto Noodle when it turned out to have a non-standard width. I had some ergo brakes lying around so I committed the blasphemy of switching them in too. Still think it looks pretty good, and it rides better than any touring bike I've ever been on. Thanks for all the advice here y'all.

Haven't had a chance to really ride it with the new set up yet, but it felt great on a spin around the local park. This isn't so much a restoration as an unrecognizable repurposing of an old frame though. (It had already been powder coated when I got it, and there isn't a single original part.) https://cimg3.ibsrv.net/gimg/bikefor...349aa8b36b.jpg https://cimg9.ibsrv.net/gimg/bikefor...a69e6b9e10.jpg https://cimg2.ibsrv.net/gimg/bikefor...b7b9a88ebc.jpg |

Your build is great. Crank Brothers pedals? They look like they really match the color. What model are they?

That's a great looking build; and that's cool getting 38c tires to fit on an old touring bike.
|
+1, sweet build. The original blue bits are a nice touch, and the mods are at modest and respect the originality.
|
Very nice build, great color scheme.

y'all are making me blush

Looks great, I like the blue and red. The only thing that I'd change is that Altus RD. Not to be a snob, but that RD is maybe a step above a big-box bike RD to to me. Far too much steel and plastic and it doesn't fit the ascetic. Looks brand new and those monster pulleys probably suck up a lot of chain, so definitely ride on with it, I'd just keep my eyes open for something to fall in your lap that is silver and aluminum and pretty.

Nice bike! What was the factory or default gearing front and back on that bike? Have fun and ride safely on it!

You have some interesting stuff going on there... The Sugino AT and the Simplex FD with the logo on the cage... were those original? If so- that must be an early 85. The 85 was specced with a Sugino LP, and most of the Simplex FDs for the 85s that I've seen have a plain cage- But the 84s had the Sugino AT and the logo'd Simplexes. Otherwise, there's no real difference between the 84 and 85 720- Only the decals, crank and FD... they were all brazed in 84. Some had 2 eyelets on the dropouts and fork ends, most didn't. I like a lot of your choices- until people have ridden on those TRP RRL levers- I can see someone saying they look ugly... but they're the best brake levers I've ever used. I like that you color matched the pedals and pegs with the frame colors! As mentioned before- I'd want a more fancy-pants RD- but truth be told, that Altus is a really nice unit- as evidenced by your picture showing it in the granny and higher gear- with NO chain droop. :thumb: But if you want to upscale it- there's always the Dura Ace 7703: https://live.staticflickr.com/4850/3...6355438c_o.jpg620 Build Derailleurs by Dave The Golden Boy, on Flickr I ended up taking off the bottle cage on the underside of the down tube- I kept kicking it and catching it on stuff- I didn't want to wreck the cage or possibly wreck the eyelets or frame. If you're going to be using this in the rain- you may wish to choose a different seat post- While the SP-KC seatpost looks really cool, it will allow water into the seat tube where it will just sit. And corrode. I have one SP-KC in use right now- and I have the top packed with grease- I'll be swapping it out eventually. Just out of curiosity- why did you change out the brakes? "Just because" (which is a good enough reason) or were there problems getting the stock brakes to line up on the 700c rims? |

I swapped it out because of durability concerns but I'll keep an eye out for that 7703! |

I got it for that "someday" Rivendell- but I think that ship sailed. The long cage 7803 is probably going on the next build. |

I will admit I ran an enormous black Tourney long cage RD on my Lambert for awhile. That thing weighed almost a full pound and it was ugly. |

What an acid thing to say. I'm more concerned about that RD's aesthetics. I'm sure it functions quite well, but aesthetically it's a bit out of place on such a classic steel bike. :P

In defense of the Altus- Schwinn's 1980 top of the line Voyageur used an Altus derailleur set...

I've had a couple older Altus RDs pass through my hands, the one with the three little cutouts on the faceplace. They were kind of heavy but I think they looked fantastic and shifted great.
I’d guess it was the typical Schwinn “overbuilt- too heavy- but indestructible” mindset that WAS Schwinn. |
Cool bikes.
Yes, those Altus and Acera are a little incongruous when you have a $350 Sinewave light on the bike... XD |

OP, no one will deny you the right to use those derailleurs but their are so many more handsome and equally competent, period correct models. |

Probably riffing off your 'ascetic' comment. Acetic acid? ;)
