nutted brake calipers

[Sir Neil d'Menture]

No, but you can get one here. Just replace the bolt on the rear brake and mount it on the fork. Replace the recessed nut on the front brake with a hex nut and mount it on the back. Easy peasy.

Oh dear...just tried that link and get all sorts of warnings. Do not use etc. Site is unsafe.
Is it just me? Could it be that they have just forgotten to do some paperwork or is there really a problem?

I get the same warning. Jtek is a legit company so not sure why the warning.

Just a validation issue with their site security certificate. Minor issue, probably due a renewal and overlooked by an IT bod before he went on holiday.

@frkl
What happened to your post?

Just a word of warning on the replacement bolt idea. I bought the Jtek bolt and fitted it without issue to some older 105 calipers.

Sadly they didn't have the reach I needed on the rear wheel so I got some Tektro 539's instead.

Despite using good quality tools and following the same process I managed to round out both bolts on the Tektro caliper, making it useless.

In the end I'm going to just enlarge the hole on the front fork to 8mm. I've ordered another set of 539's so I'll use both front calipers, though apparently a rear will also fit on the front with an extra long recessed nut.

If anyone ever needs a broken front 539 or a brand new rear one let me know

Edit: or indeed a Jtek bolt!
