I am looking at purchasing a Fuji 2.1 SL frame only for a couple hundred bucks.
Issue is, there are no shifter components for it, it is just a bare frame. As you can tell from this listing, it used Ultegra Di2 for the shifters with Rim brakes.

I was wondering how hard would it be to put my Ultegra 8000 group set on this thing. It has mechanical shifting, not electronic.
Does this frame share the cable routing for the front and rear derailleur as a non-Di2 frame would have?
The only worry I can guess at would be the cable routing under the BB and back thru the frame for the front derailleur.

Am I crazy for wanting to try this update?

If you go closeup on the picture you'll see gray ports near the headtube for cables. Most frames of this type can be built mechanical or Di2. Especially back in 2016.

The problem you are likely to run into is finding all the hardware that allows the cables to go in and out of the frame. You can certainly coble something together, or find a Fuji dealer that has some sitting around, but it may be frustrating.

But if the price is right, maybe you're up for it.

That bike is meant for a full-race bike with a light weight rider...Are you a light weight Racer able to handle a twitchy race bike on downhills? 73* is a Steep head angle. they are known for a cramped, low rider position too... not an option for most older riders, IMO.

If YOU are up to riding a quick steering bike like that, I'd question why you're asking us for info.. Is the deal local or an internet purchase? Buying a super thin CF frame over the internet is risky. I'd want to carefully inspect the frame before purchase..... in the sun... with a magnifying glass.

it should build up into a sub-17 lb. rocket ship...

None of this is true. 73 is a very standard road bike headtube angle, and is only used in the 54 and larger sizes for this model. Handling is primarily dictated by trail, and the fork offset of 43mm combined with the 73 HTA yields a stable 59mm of trail. For larger frame sizes, 73 is pretty slack. 61cm frames are often 74 degrees (and still stable).

The two most predictive indicators of handling are the wheelbase and the trail.

I cannot get a picture of the underside of this bike. Thinking I can pull the cable guides off of mine and make them fit the Fuji, but if the bb will not take the underside cable guides for the derailleurs, I might be wasting my money.
Thanks for the info.

Your second-hand frame might be some missing ferrules and cable stops, but if you're up to hunting around I see no reason why it shouldn't work. Best of luck, and don't be afraid to ask questions as you get into it.

It is internally routed. You can always use full length housing. Some of the newer Shimano front derailleurs even have cable stops.

ok.. then why did every review i read call the Bike "twitchy" and also say it "steers a bit to fast on downhills"? Maybe everyone else is wrong too? and i'm well aware that sky scraper bikes have Steeper head angles.

i should have left you blocked. bye.

Because most cyclists just repeat stuff they hear instead of reading up on stuff.

By all means, be angry at me that you are repeating nonsense.
