Need some dark side help.

Had a 105 brake rear brake caliper sitting in my bike box and put it on a bike last night, but for the life of me I could not get the brake blocks to sit over the braking surface of the rim, they just don’t reach that far down. I have slid the brake blocks down in the slots on the brakes as low as they go and still they are about 3-4mm to high and basically grip onto the top of the rim and the bottom of the tyre.

Anyone have and bright ideas? Have I done something wrong?

Please help!!!!!

Cheers

Road brake calipers have different ‘drops’ I believe

you need deep drop (58mm ??) road brake – i.e. the ones they use for winter bikes /bikes with mudguards

You’ll be needing some 57mm drop brakes. Sounds like you are putting standard drop brakes onto a winter frame.

that would make sense as it is an old steel planet x frame with mudguard and pannier rack mounts. that is a pain – i was suppose to build it and take it to france on saturday. could be some sprinting aroudn the LBS tonight I feel!

thank you all

Can’t you fabricate something to drop the caliper a bit?

You’ll find some easilly. If you want to play safe I THINK that Tiagras are 57mm only.

I bought a frame from Fleabay that turned out to be a cut and shut. Shallow brake for the front, deep for the back.

very tricky as the bolt goes through the frame and the pivot of the caliper.

I got some decent 57mm Shimano drops from Ribble earlier this year. If you want to spend less, then Tektro do some reasonable budget ones.

You need something like this:

These might be worth a look too

thanks all – will go see what i can get.

My Ribble winter bike as supplied needs a deep drop front, but will take a shallow drop rear – handy given that mrs aracer’s Tifosi needs a deep drop rear but works with a shallow drop front, hence I only needed to buy one pair of deep drops between them (and could re-use a pair from my parts bin for the other end).
