  • Running a pompetamine as a single speed, currently to remove/do any sort of rear wheel adjustments (or even if I had a puncture) I have to to loosen then disc brake mount in order to that I can slide the wheel sufficiently forward to have enough slack to decouple the chain/remove the wheel without it fouling on the caliper.

    This is clearly not ideal as I have to go through the rigmarole of trying to find a position for the wheel (within the dropout), chain length/tension and caliper positioning that works (and reset up the bb7s, somewhat fiddly), this generally takes some time and swearing, I seem also to always end up with the chain slightly slacker than I would like.

    Are there any solutions to this, I would like to be in the situation where I can change a puncture in less than an hour! I get the feeling that ultimately I would be better with a standard drop out frame and an eccentric bottom bracket to adjust tension, or the clever drop outs on the nature boy disc that move the caliper as you tension the chain (is anyone else producing a similar solution to this).

  • Sliding dropouts

    Rocking dropouts:

    I have sliders on my SSCX, they work very well. There are few OTP frames that come with these (hence why I went custom) but the Specialised Awol has their own version of rockers, which could work for you:

    All of the above also allow the wheel to drop out vertically, meaning even with single speed you can change wheels/tubes without moving the position of the dropouts

  • All look good/better than what I am facing with the pompetamine commuter, hopefully having sorted a new chain it should not require touching for at least another 6 months. On the plus side I have decided to stop commuting with a tool kit as I am not going to be doing this roadside.

    Considering options to get to a better situation, cheapest is perhaps ditching the rear brake and running a fixed hub (never tried fixed so could be fun, Nottingham is however quite hilly in places, though not my commute), more expensive being to have new drop outs welded in (~£100 cost similar to pomp frame price, seems a bit mad) or new frame/bike, either the commuter or downgrade my nice bike to ss (with an ebb) and buy a new 'best' bike...I suspect I will just persevere, luckily I have been very lucky with punctures/vittoria randonneurs are amazing?
