Is it reasonable to run a cable actuated disk brake on a Cannondale CAAD13 disk frame?

I haven't done it, but would also be hesitant that the cable setup might be irreconcilably bad. This picture from the CAAD13 supplemental manual shows the hose routing at the BB: And this one shows ...

Brand new bike. Briefly removed the rear disc brake caliper, now it's too tight

As mentioned in comments you most likely applied the brake without the disc between the pads. The pistons advance and do not return all the way to their original position - this is how hydraulic ...

What are my options for correcting a bent aluminum fork?

It's not clear what is actually bent. From your picture, it is obvious what isn't bent: your fork is perfectly straight from the crown down to the drop outs. Also, the boot which covers the stanchion ...

Cannondale CAAD Optimo Tiagra 2020 CREAKING

Safe to ride racing bike with dent in frame? (with images)

With all frames, that much of a dent increases the risk of a failure eventually. If that were an ultra-light frame with very thin tubes, it might be better to retire that now, but an earlier model ...

Help me identify the model of this Cannondale frame

I don't believe it is a Cannondale. Here's why: It has a downtube decal on both the down tube and the top tube. Companies are very picky about branding and this is not how Cannondale labels it's ...

Frame Or Paint Crack (Cannondale Super Six Carbon)

Since it's a few seconds with an allen key to pop the stem off and have a look at the inside of the head tube, I suggest doing that. Strongly suggest. If there's any damage to the fibres, or the ...

Pros and cons of single-sided forks (Cannondale Lefty)?

Con: Because there is only one side on the fork, it limits you to using disc brakes only, since there is no place to mount any type of rim brake solution.

Can anyone help me identify this bicycle frame?

Replacement for Suntour Superbe Tech Rear Derailleur

As 83cannondale alludes to, this was an unusual derailleur that, unlike most others, did not use a cable housing and the frame has no cable stop for it. So you'd need to get a clamp-on cable stop ...

Cannondale warranty

The only answer to this is to go to the store where you bought the bike and ask. IMHO: seems derailleur hanger failing to protect the chain stay seems like a possible cause for a warranty claim.

How can I install a 1 1/8" to 1 3/8" Synapse fork onto a 44 mm headtube?

A lower akin to an EC44/40 could be made to do this, but it doesn't exist commercially. In other words it would be an EC44 frame interface and take the sort of bearing that goes in IS49, whereas EC44/...
