Upgrading Trek 1400 from 7spd. to 9spd.

[Mark E. Touchette]

I would like to know can I upgrade my trek 1400 from a 105 7speed to a 9
speed 105 ? I don't mind if I have the downtube shifters I am used them for
so long I just don't know any better. I know it would mean getting a new rim
and hub.
Guess I am trying to give a old friend new life.....

Thank You

Measure the inside of the rear dropouts...they'll need to be 130 mm. If
less, the rear dropouts will need to be spread out.

Do yourself a favor and get STI. Ignorance in this case isn't
bliss..

If it is a cassette hub, which I think it is, you need:

A 8/9 sp hub body. You can find these used or buy one for ~$25.
Add 2 mm of spacers to the non drive side of the rear wheel ( make it
spaced 128mm).

Tighten each of the spokes on the drive side 1/2 turn and that will be
close enough for a redish. You may have to center the brake caliper.

Get a 9sp cassette.

A 9sp chain

9sp shifters.

It would cost about $100. What's wrong with 7sp?

Keep in mind that 7 speed dropout spacing is 126mm and 8/9 speed is 130.
the 8/9 speed wheel will be hard to get in there and the dropouts won't
be aligned all that well when you do. It probably won't hurt anything
and probably shift OK though. I would just replace the worn 7 speed
parts. Replacement parts are still available.

Spacing was not a problem on my '90 Trek 1400. And yes I understand the
spacing issue, but I have used 130mm spaced hubs (Shimano 600) on my Trek
1400 since '95.

The frame does not have to flex/bend to accommodate the wide hub. Why?....
because Trek was into thick paint back then and after the first 4 years of
installing and removing the rear wheel, the paint chipped and fell off until
the aluminum dropout was exposed. There was enough paint on there that when
it was gone the resulting spacing was perfect for my 130mm hubs.

But, that may not be the case with your 1400. I'm now in the process of
rebuilding this bike with it's original parts and the first wheels I ever
built as a tinetrial bike. In this case, 7sp is all I need. and my downtube
shifters will work fine since they'll be on aerobars anyway.

Cheers, Jason

I never did make the switch on my Trek 1400, but the guy I contacted at Trek
said "It will be fine to use
8 speed with a 126 mm spaced dropouts". Now I have a frame with 130mm dropouts
and I am still riding 7 speed...

Have you actually tried this or are you just speculating? As it happens, I own
a Trek 1400 that originally came with a 126mm 7-speed hub. A 130mm 8-speed
snaps right in; no problem!

Well, I just tried it and it does work OK. It doesn't go in as easy as
the 7 speed wheel but it's acceptable. It definately doesn't have to be
forced or jammed in, so I stand corrected. That's good to know in the
event I can't get 7 speed parts anymore.

Do you know what year model the bike is?

The 1400 series went to 130mm spacing in '94 and the 1420 in '93.

Best of luck with your project!

TWENTY-TWO YEARS LATER the project is probably finished or abandoned.

Never the less it would be interesting to know if he completed the project.

If he didn't have a 130 mm rear triangle the 1400 is aluminum and I don't know if respacing it would be advised.

[Roger Merriman]

Bending aluminium isn’t wise, I had a old 10s road bike ie 2/5 that being
steel when it was upgraded to 10s I just fitted the new wheels fine as it
was a steel frame!

My old MTB is 9s admittedly 1by as it’s my commute bike, so a flat mostly
route.

My Gravel and MTB are 10s and the extra cog on the cassette does make a
difference in terms of less swapping chainrings and so on. The Gravel bike
had been 9s but my need for hydraulic also gave me 10s which has been a
minor improvement as the cassette has a slightly wider range.
