Many thanks. I'll stick with what i have, for the time being. I will get some new blocks (better) though. Blocks and rims are fairly new, but the blocks seem to turn to mush whilst braking when wet, ie this morning. Cheapo stock ones, i suspect.
That photo reminds me of coming in to finish my second London Marathon. 100 metres before the finish line, i realised the guy in front of me, had had a case of runner's trots, so veared off to my right to finish under a different gantry. Didn't want 'that' in my finishers photo.
My bike came with Tiagra group set, but the calipers are unbranded. Stopping power does not feel great, especially when going downhill fast. I thought about buying better pads and also thought about buying better calipers, such as 105's or Ultegra's, but wondered if I would see much difference and whether they would be compatible. Any views?
