Upgrading a frame to take modern brakes
« on: May 28, 2009, 09:36:46 pm »
I have an old (not that old really - early 1980's) Raleigh Sensor. The frame is made of Hi-Ten steel. The problem is that I'm used to modern brakes now, so found the single pivot Weinmann Alesa brakes not quite up to scratch. So, armed with a power tool, some HSS drill bits and a set of Tektro dual pivots, I set to work.

Starting point





N.B. You only need to drill out the rear side of the crown. The front stays the same size.

After a 7mm drill bit

After an 8mm drill bit

Dual pivot lovelyness  8) ;D :thumbsup:

I wouldn't recommend this procedure on anything other than a steel bike.

Or buy nutted dual pivot brakes  ;)
Never tell me the odds.

The best way to do that is with a step drill bit, looks like a cone.

I'm with Roger on this using nutted brakes  .... or in reality I would have probably just pulled the levers on the original brake a bit harder :thumbsup:

Me too - on my Aende road bike. Good nutted brakes were no longer available and it wasn't that difficult. Slightly harder at the back (seat tube in the way) but no great problem.

Tektro and Alhonga, used to be one or two Shimano as well.

To be honest, rather than getting special brakes I'd recommend just modding the frame.  I've done it too and it's really easy - just drill out a couple of  holes.

but mr rogerzilla sold some alhonga's to me for such a good price, why waste time drilling out some forks.....

I've done that mod on a few old frames to fit dual pivots. I don't really have any nostalgic feelings towards single-pivots, not even the top-of-the-range campags that I used to think were great at the time. If the frame is a piece of history then maybe worth keeping it original, otherwise might as well modify it.
