WTB Hidden Brake Adapter for Track Fork
 
Before I order one from Japan, wanted to try here first. Will be using it for my Raleigh Track bike. I’m not as good as I used to be stopping myself so definitely need brakes.

Thanks,
Asifi

The online example shows a sculpted fork crown that likely gives the adapter enough clearance. I'd want some exact measurements, especially with the diameter of the quill that inserts into the steering column.

I think I'd rather sub in a road fork painted in Raleigh livery. Maybe less expensive by the looks of that piece?

I've not seen a solution like that before... pretty neat.
Here's hoping you can make it work. Be great to keep bike unchanged. Let us know what you do...
Cheers, Eric

That's really clever. I have a Raleigh track bike just like yours but smaller. As I received it, my fork was already drilled for a brake, and that's good for me. Are you trying to avoid that?

My Witcomb came drilled as well, but I don't know that I would take a drill to it, if it wasn't. The purest of the pure, and all that. Though it was a very common mod BITD, since many of us had no reasonable access to tracks.

Yes, trying to avoid drilling. I was open to drilling the fork before I saw the couple of alternate solutions. I found this option in the forums actually and someone mentioned there is room for up to 25c tires but it will be cutting it very close.

I am not able to help with your inquiry, but can you please link that Japanese solution you found please?

Good luck!

Interesting. I've never seen that though I did run across this awhile back - no track bikes in my inventory so it was just a curiosity. Not as elegant as what you posted and pricey, but no tire clearance issues - you probably have seen this... https://www.ebay.com/itm/Dia-Compe-K...-/302047062655

Cool bike, and a cool adapter. Keep us posted as you proceed.

I wonder if one could 3-D print that doodad.

Thanks for the link! I've been looking for this adapter for years.

After lots of research I ended up using this one, with the correct clamp shape for the blades of my fork.

It does flex quite a bit, and doesn't serve as a true front brake. At best it's a brake for trailing, not sure how it would hold up if one were to grab a fistful of brake in an emergency.

The insert-style caliper mount does look super clean, but I have the same reservations as others about fitment/clearance.

An update for those who were interested. The adapter ended up working out for me. I used a rear brake and a steel spacer (don’t recall the exact name for it or measurements) from Dale’s Hardware. The tires are 25c.
Plenty of stopping power and no play.

Looks great, but please reinstall the brake pads with the open end of the holder facing backward. You don't want the pads launching themselves out of the holders in a panic stop.

jeirvine 11-05-19 08:50 AM

That there is a cool gadget, and a very fine bike. I would ditch the spacer and cut down the bolt, but if it works fine, then it would just be for aesthetics.

Yeah, flip them around... But ever try to get a pad out of those record shoes? Even bitd?


The bike looks awesome. Congrats.:thumb:

No need to remove the pads, just swap the pad holders and all, right-for-left.

No one said to remove them. He was saying that the difficulty of removing indicates that the danger isn't as bad as it appears. I might not agree with that, but it's a point. Removing the pads from their holders does nothing to reduce the problem, though, which is why no one suggested it.
