Modify Eclipse/Cannondale front mount for riser stem?

Has anyone tried this? Seems like it might possibly work if one could manage to rework the curve that goes around the bars, but it also looks like there might not be enough steel to make the curve long enough. I would hate to botch a perfectly good bag mount by experimenting if someone already knows it’s a non-starter. TIA for any thoughts or advice.

Yep, there's enough material to rework the bracket for a riser stem.

I sort of strongarmed my holder but if someone is doing something more elegant I am interested.

Some company made something like dummy hoods for attaching the Cannondale style bar bag mounts to bull moose bars... that might work...

I think I know what you’re referring to. There was also a gizmo that mounted to the seatpost to allow rear hanging. I have thought about looking for something like that, or fashioning something from hardware that could clamp to the quill. I have not come up with a decent idea though and I would rather not add more hardware if I don’t have to.
Thanks for the replies. I am encouraged. Those who have done this - did you just hammer away at it cold, or heat it?

I'm not so imaginative, but I would guess someone could engineer something like this to work with the stock hanger for a riser stem.

Sorta like one of those Nitto handlebar mounted light hangers.

I zoomed in on the image and the seatpost adapter to bag bracket appears to have an Eclipse logo. I plan to replicate the design and use my Cannondale front wire support once again for our Santana tandem. Probably will tie the bottom corners to the stay tubes. After 35 years since purchased new, the Cannondale stuff is not too bad.... lol

On a related note I've been wondering how to adapt a later style Cannondale Trestle bag with the quick release handlebar mount to attach to a front rack. Haven't got that figured out, so any ideas are welcome.

I use an Eclipse Pro front bag and bent the holder to fit my riser stem. Here's the bike with the bag on it. I'll get a closer photo. I did the mod by putting the holder on the bike without the bag, then put a big Crescent wrench on the holder and bent it as needed. Took about two minutes.

Looks like the same bag I have. I’ll give it a go.

IIRC, that device was called the "Seat Post Thing", or SPT for short. I saw somewhere recently that someone had used a threadless stem with a shim around the seat post to accomplish the same thing.

Those bags are all meant to be suspended, rather than supported from underneath.

Right you are. I'm wondering about clamping something to the rack which would then support a piece of old handlebar or similar diameter tube to attach the handlebar mount to.

I know you said rack... but how about something like this:

If there was something that resembled that but mounted to the quill, tthat would be cool.

there’s also the option of 2 clamps and/or a longer bar.

Is it possible to use the Nitto F15 front bag support with old Cannondale bags? Anyone know? They aren't exactly cheap, but it seems like it would do the job if the width dimensions are correct. I'd imagine the bungees could be omitted if using this instead of the old style wire loop support.

Then again, simply bending an old Cannondale wire type bag support would be a lot cheaper and simpler. Or, if you had to make your own support from steel rod, how hard could it be? Dip the part that goes around the stem/bars in Plastidip when you're done, or use heat shrink.

Or just get it powder coated. How much could that cost?

Reporting back with success. It was a bit more challenging for me than others made it sound, but whatever - it’s done. I used a bench vise, adjustable wrench and hammer. It was fairly gnarly by the time I had gotten the shape right, so I did some filing and sanding and rattle canned it. Then stitched some leather around the interface portion to protect bars and stem.

I’ll take pictures of the ugly fork mount I made. I used two inches of pvc pipe and a hose clamp.

I think I did something similar. I used a small cutoff from a junk handlebar, a bar plug with longer replacement bolt, fender washer, rubber washer, p-clamp and a bit of bar tape. I am using a Twofish block to hold the flashlight.

OK, here it is. I guess I used 1-1/8" or 1-1/4" pipe. I cut it to length and then filed it to match the contour of the fork. Then I sawed slits in it with a hacksaw to let the hose clamp through. I attach a light with a handlebar-type mount.

Looks simple and effective. Any worries about clamping to a carbon fork? I don’t know a thing about CF and likely have an exaggerated idea of its limits.
