9-speed spacing(5 posts)

No laughing! I have a Trek 2300 (carbon main tubes, aluminum rear triangle) that has a 6-speed rear cluster. The rear dropout spacing is about 123mm and I want to upgrade to a 9-speed and believe a DuraAce hub requires 130mm spacing. Do I have to take my frame to a builder to get it bent out? What do I need to be aware of if this is the route I have to go?

You can't spread aluminum safely. has an article on the issue if you want to explore further. In short, steel can be spread, but with aluminum you need a new frame.

you CAN jam a 130mm hub in there. The wheel will never be easy to get in or out, but it will work. You'll need three hands to put in in. The hub MAY have a shorter life-span, because the drop-outs won't be parallel.

The stays and dropoouts may also have a shorter lifespan. Not something I would recommend to someone else.

You can use a 126mm hub, and put 8 cogs of a 9-speed cassette on it. That's the best you can do...
