What are these for?

I was surprised to find these bolt attachment points on the seat stays of my wife's 2008 Specialized Allez, since it is marketed as a racing bike.



Are they for a rack? There are no corresponding attachment points near the dropouts.

Also, the cable routing for the brake cable is too high, right (housing too long)?

Looks like a rack mount to me. If you bought the bike used, they could have been added by a previous owner; not hard to drill a hole. The brake cable looks fine to me.

Those seat stay screws are for a rack.

Imagine a big bike frame building factory. The first thing they do is to cut, bend and otherwise fabricate all of the individual pieces. It's cheaper if they can use some of the same frame parts on more than one frame model because then they have fewer parts to inventory. The result is bread and butter frames that might have rack mounting points on the seat stay but no mounting points on the dropouts to give a cleaner look.

They are rack mounts and the housing length is good.

Yep, rack mounts, just because it's a racer, doesn't mean it will never have a rack fitted, there should also be some holes / place to mount near the rear dropouts.

If doing long distance a rack pack can be useful (bar & saddle bags are alternatives)

The rack mounts are standard on some of the Allez models, so not added by the previous owner.

Yes, they are the upper eyelets for rear rack. That is an Aluminum Frame which almost ALL have the mounts for REAR racks. If it has carbon front fork, there will be no front rack option.

As the others have said they're definitely for a rack, and if you don't have corresponding eyes on the dropouts it might be because the maker prepares all their seatstays for the various versions of their frames, but on yours elected not to include fender eye dropouts. (Which IMO is a major sin committed by the bike factories today, given the tiny weight consequences vs. the user options they create).

The seatstay mounts provide more rigidity to racks, and you can always use P-clips at the lower end.

As to the brake cable. I think it's a bit long, though I should add that I'm a fanatic about fair lead in cable runs. Every curve in housing causes friction, so you want to avoid reverse curves like the up curve coming from the frame fulcrum. I know it's hard on a frame as short as yours, but I think there might be room to bring the height of the loop lower for a better run. OTOH, if it works it isn't worth changing, but might be worth trying next time.

You can still put a rear rack on it,
just use the QR Axle skewer as the bottom mount.

The kit for like Tubus racks will also move the rack backwards a bit,
to make up for some of the race bike short chainstay problem.

There Is a rack-mount, above the replaceable hanger in #6 picture.
It's just not threaded, [ need a thread cutting tap ] yet.

That hole above the RD Hanger/RD is for the eyelet/extender for one.

Hi Al - personally I`d suggest you leave the cable housing as is. The real issue is a poor positioning of the braze-on resulting in an awkward cable run. That guide on the brake housing will actually drop as the brake is applied and if you shorten the cable housing you`ll end up with a sharp kink in that section of the housing. The current installation may not be ideal, but its probably the lesser of two evils.

Just drive it and have fun!

I really don't understand the rationale of having seatstay braze-ons without dropout 'braze-ons' points. The threaded holes at the dropout are just threaded holes on a (slightly larger) piece of metal that is anyways part of the bike. seatstay braze-ons are actually another part that is attached to the existing seatstay.

TA, The rear brake cable routing is as good as it'll get for a small frame.

Yes, there is a hole near the dropouts, I just missed it.

Thanks for the info!

The housing is on the longer side of being OK. It could be trimmed by maybe a 1/4 to 3/8 inch and form a smoother line coming off the top tube housing stop as long as it doesn't try to get too sharp at the caliper arm. You still want to have it loop up high enough that there's some movement in the housing to allow for the caliper arm motion as it closes and not develop any tension in the housing. It's great at the caliper but not quite perfect at the housing stop. But this is splitting hairs. It's actually very servicable as it sits and only us over the top fanatics would bother to shorten it by a hair....

It's a compact frame, which I wish no one had invented. Here it is pre-cleanup:
