    As I suspected and other posts confirmed there's a high chance they weren't bedded in properly. Honestly those brakes (when in proper working order) do not warrant any upgrade needs. They will be highly sufficient for your missus.

    They do not require better pads, better rotor or even a bigger diameter rotor. The most effective thing you can do to your brakes is service them properly & have your pads in good order.

    Out of all of my disc calipers & regular brake calipers, the most currently hard-stopping brake I own are the Infamous avid BB5s, so even a bad quality brake can indeed stop fast and hard when you need it too.


    Do not get overly paranoid about your brakes being insufficient, trust me, they are perfectly fine.

    I have mechanical TRP spyres with crosslever brakes on the Boardman. They work fine and more reliably than the BB5s they replaced which were ok when adjusted but just needed adjusting way to often for me

    ... you chose spyres over bb7s for the boardman? egh.

    Also yes, for the love of god, avoid the avid bb5. While mine work perfectly right now, I'd like to say that there is a special place in hell
    for whoever came up with those 5s.

    Why not Spyres, everyone I spoke to recommended them, needing minimal adjustment, which is easy (I'm not mechanically mined in the least) ...and they were cheaper?

    I think bb7s are cheaper.
    to me, spyres are a great standard to set disc brakes too, but bb7s are just that slightly more exceeding. They definitely learnt something from their previous model though :smile:

    Don't know, the Spyres cost me £80. They work well, the LBS who fitted recommended them before I bought

    Disc brakes can be shockingly poor, but here is a little anecdote about an experience I had.
    One of the kids bikes was stolen a year or two back. When it went it had excellent Shimano Deore M615 hydraulic brakes, they really did perform as well as my XT brakes.
    When we recovered the bike the little scrotes had stripped the brakes and installed (badly) some Tektro cable operated shoot (Novela I think). They had also swapped the good wheels for junk so we now had generic unbranded rotors in place of some end-of-line discounted XT centrelock ones I had managed to pick up.
    It couldn't have been a much worse situation but it was what it was so I set about 'optimising' the set-up. Cable routing and condition was sorted out, pads sanded up nicely and caliper adjusted to perfection. Still not great but better. I left them alone for a few weeks thinking they would bed in, but they actually got worse, to the point of being dangerously ineffective!
    Time to get serious! Pads out and they looked dry but a little glazed so these got cleaned with a solvent and then rubbed up again and looked like new. Rotors were removed from the wheels and mechanically sanded until all traces of polishing had gone and both sides had a uniform satin/roughened finish. All now went back together and adjustment once again checked/tweaked to perfection. I then forcibly bedded them in myself and they got better, almost acceptable and now certainly not dangerous, but probably about as good as could be expected for a cheap set of cable operated disc brakes. (I have had no other experience of cable discs but have had the misfortune of Tektro hydraulic brakes which soon went in the bin!)
    Over the following weeks, performance fell off slowly until it got to the point where I wasn't happy for my son to use the bike. I was ordering some bits for other bikes so decided to stump up and buy some new pads (Under £20 for 4 pairs semi-metallic, enough to do the bike twice).
    I don't remember doing anything other than popping these in and adjusting clearances but on the first bedding in run the bite went from hmpff. to Whoa! On the second run the brakes were right up at the WOW! level. I would never have believed cable disc brakes could be so powerful, especially cheap ones. I guess the fact that I had done all the groundwork to make sure everything else was optimal helped but these brakes remained really good until we passed the bike on several months later. I would previously have rejected a prospective bike if it had come with cable operated disc brakes but now realise this would be a mistake.

    @Crackle I guess this is your problem, the bike your wife experienced probably has contaminated brake pads or they need setting up properly. I suggest you tell the shop to sort it out as they will lose the sale unless they can get the brakes working as they should.

    I'm leaning towards the 1 because I think I'd like the option of fitting cross levers, still mulling though and I might ring the shop later and ask some hard questions.

    Sounds wise. The hydraulic hoods are really big imo for smaller hands (and ugly as a result)

    Arkose 3 2015 owner here. Mine came with BB7 cable brakes. Worked fine but would need adjusting fairly frequently and I used to find that if I took a wheel off when putting the damn thing back on I would often have to adjust the brake again. Moved to hydraulic and whilst no perceptible difference in power so far no real adjustments needed.

    Good luck with whatever you choose to buy, I'm a big fan of my Arkose.

    Have to admit. I do miss my Pinnacle sometimes. Rock sold, well made, well specced bikes.
    Your one looks a cracker @Crackle :okay:

    It's a really nice bike. Mrs C did her first ride on it this morning. No neck pain, only a little bit of hand tingling and she said it felt good, smooth and fast. So so far I think I've judged this right in trying to solve some of the problems she was having on her Cube. Need to swop the seat over from that and re-adjust the gears which were jittering under pressure. I did try to do it on the ride with the in-line adjuster but it was a bit cold to stop for long. She was very happy with the brakes and the bike overall.

    I think the Arkose range is really well specced and designed. I'll probably need to change the gearing for her but I was expecting that but other than that, it's all good. Really lovely bike.

    I really detested the supplied bar tape and changed that very soon after buying, your mileage might vary but changing might help the hand tingling?

    Tis a lovely bike, you spoil that woman.

    Tiagra groupset should be excellent if my previous 9spd Tiagra experience is anything to go by.
