• cleaning the commute bike

    From Roger Merriman@21:1/5 to All on Sun Jan 19 14:33:37 2025
    In slightly disappointing news I’ve discovered that the Old school roadie commuter does need to be cleanse or shifting becomes hit and miss!

    Unlike the old MTB who’s cables run safely out of reach of muck and grime
    the roadie runs the shift cables around the bottom bracket, which collected salt/grime which eventually stopped it shifting reliably to the big ring.

    I use wax based lubes so the drive chain remains clean, but it hadn’t occurred to me, that it would pack up on the commute! Off road is one thing pounding the streets of london is another!

    Has been cold and so frosty roads plus salt etc, ie mucky roads but even so cleaning commuting bikes I’m not sure I approve of the idea!

    When my friction shifting drive train starts feeling odd, I always check those plastic cable channels under the bottom bracket. They're easy to forget, and they can get clogged with road grime.

    I think I had less of that problem with the older style metal channels
    brazed on above the bottom bracket. But I don't ride those bikes as much these days.


    I get that with the gravel bike as with that the front mech cable runs
    under the bottom bracket, and is easy to overlook, somewhat daft choice for
    an off road bike really.

    Though with that just exhibits as slightly slow shifting, the old school
    bike it wasn’t the channels but that muck had built up between the
    chainstays and bottom bracket and this was enough to stop it reliably
    shifting to the big ring, it’s shifting is somewhat sluggish and i suspect could be improved, but that like other things can wait.

    Wireless shifting might come to the rescue. :-)

    I avoid these conditions nowadays, so I can't report on how the rear
    derailleur deals with dirt and especially salt. Most probably not worse
    than a mechanical one and perhaps better.

    Years ago, when commuting around the year, I had both spare cable guides
    and cables in my toolbox. Using a a little bit of grease helps, but
    can't help with corrosion on salted roads, in the long run. Replacing
    both the inner cable and the cable guide after winter is a more reliable solution. These parts are cheap.

    Depending on the frame, it might be difficult to route the housing
    through the bottom bracket.

    Through the bottom bracket? I wasn't referring to running it through

    Catrikes have no bare wire except right at the deraileurs.

    Maybe for you but it goes both ways.

    Full casing is very prone to moisture and crud and less
    easily cleaned. On split casing, one snaps the casing out of
    the stop and slides it back along the wire. Takes just a minute.

    Yes, it is.

    Modern carbon frames replicate the problems we solved forty
    years ago.

    I never thought of that. I just replace the whole thing regularly, but
    it did get to be a little more work getting the inner wire started
    through the trigger shifter.

    Maybe you are refering to your nonstandard frame. Roger was talking
    about his "roadie", so most probably about a diamond frame.

    <https://en.wikipedia.org/wiki/Diamond_frame>

    The cable routing for the rear derailleur is usually like this: The
    cable is routed open along the down tube on its underside and from the
    cable guide under the bottom bracket further to the end of the chain
    stay. So there are only two short cable housings, from the shifter to
    the headset or top of down tube and then from the end of the chainstay
    to the rear derailleur.

    I’d expect so or even electronic as well sealed systems, though not really
    in the spirt of the cheap roadie!

    Wasn’t actually the cable guides under the bottom bracket but muck
    collecting between the mech/chainset and the chain stays which clogged the cable and it’s guide.

    I’ll keep an eye on it!

    FWIW, the worst of these problems I ever had was with my first mountain
    bike. To turn the front shift cable upwards from the down tube to behind
    the seat tube, it had a short (maybe 6") of cable housing. Both ends of
    that housing pointed upward, and inhaled water and mud. I did ride the
    woods in winter back in those days, and the moisture in the housing
    would freeze, locking up front shifting.

    The open metal channel guides atop the bottom bracket gave the least
    trouble IME. Plastic guides under the bottom bracket need occasional
    cleaning and lube, but were also far better than housing.

    Early and mid MTB were essentially just over built road frames, and some
    did come with some questionable cable routing particularly for a sport that
    is likely to encourage mud and water.

    MTB frame’s are quite a bit more designed this century some of which coming from the rise of full suspension, but also designing the bike for its
    intended use.

    Indeed certainly with the roadie which is “old school” so apart from rim brakes and so on, has mostly external routed cables, in that it’s internal only on the down tube where it’s routed around the bottom bracket, using
    the cable guides with both cables from there on be largely exposed to the elements.

    The Gravel bike bar the bottom bracket guide the internal cables are
    largely that, or at least enclosed, it also runs the rear mech via the top tube, which as a MTB brand makes sense.

    It’s largely fairly tolerant of mucky conditions.

    As is the MTB though that’s internal routing gave ample opportunities for muck to get in, so has an external but fully enclosed cable, which has just worked for years now!

    I think I see the housing refered to as cable guide. Our
    Catrikes have no bare wire except right at the deraileurs.

    Certainly. But I expect that electronic shifting, whether wireless or
    wired, will become just as cheap or even cheaper than purely mechanical
    parts, in the long term.

    I am imaging a future road bike where a central energy and data bus
    supplies energy by internally routed wires to every relevant component,
    from lights, derallieurs, switches and control panes. I'd move an
    optional hub dynamo from the usuall location in the front wheel to the
    rear and put an optional battery into the seat tube, like Shimano does.

    A suitably dimensioned ultracap at another point inside the frame could
    be used to supply the lights and electronics when stationary if neither
    a battery nor a hub dynamo are installed.

    Even very cheap bicycles are sold with hub dynamos, nowadays. I expect a slimmed-down version of the above might become available, too.



    I avoid these conditions nowadays, so I can't report on how the rear
    derailleur deals with dirt and especially salt. Most probably not worse
    than a mechanical one and perhaps better.

    Years ago, when commuting around the year, I had both spare cable guides
    and cables in my toolbox. Using a a little bit of grease helps, but
    can't help with corrosion on salted roads, in the long run. Replacing
    both the inner cable and the cable guide after winter is a more reliable
    solution. These parts are cheap.

    The cable guide is in the open, on a place that is exposed to salt, dirt/salt/water/mud from the road, so it will collect debris, resulting
    in a corroded or stuck cable. In my experience, parts where the cable
    runs in the open without a housing/cover are rarely a problem.


    I’ll keep an eye on it!

    Cleaning and a little bit of grease now and then helps. When in doubt,
    replace both the inner cable and the cable guide. These parts are cheap
    and easy to replace.

    I agree with you that electronic shift will displace most

    products, that's highly likely to go wireless rather than
    cables.

    Certainly. But I expect that electronic shifting, whether wireless or
    wired, will become just as cheap or even cheaper than purely mechanical parts, in the long term.

    Possibly some things do remain more expensive, hydraulic disk brakes while certain can be bought cheaply cable disks can and do undercut them, tend to start at the £400 ish level for Flat bars, due to the drop bars having brakes/shifters in one, that point is £1000+ though I’d expect that to fall as more hydraulic moves down the group-set range.

    Even so I’d expect cable disks to retain its niche as the budget disk
    option.

    My commute bikes don’t get a huge amount of love, and are essentially tools so I’d be cautious with anything that adds battery management, I don’t mind charging stuff but I want a gauge not just a red light I’m at 10% power
    etc, hence the roadie has a connected light which gives the battery level
    on the Garmin, the bike light will last up to 24hrs and has a traffic light gauge plus a run time counter to the rear so it’s very easy to live with
    plus it works the way I like.

    I am imaging a future road bike where a central energy and data bus
    supplies energy by internally routed wires to every relevant component,
    from lights, derallieurs, switches and control panes. I'd move an
    optional hub dynamo from the usuall location in the front wheel to the

    I’m sure your right but i suspect you’d be horrified ie be a E bike not dynamo driven.

    A suitably dimensioned ultracap at another point inside the frame could
    be used to supply the lights and electronics when stationary if neither
    a battery nor a hub dynamo are installed.

    Even very cheap bicycles are sold with hub dynamos, nowadays. I expect a slimmed-down version of the above might become available, too.

    Different market conditions here dynamos are essentially a niche product
    and either an old bike that’s been kept going or aftermarket parts added
    and so on.

    I’d assume they would in time get replaced by battery packs be that in E bikes for utility bikes etc.

    At some point it will need a proper set up as it was set up by the bike
    chain store and I suspect non optimal ie seems a fairly clunky and I have
    had Sora before its perfectly possible for it to be better.

    But that can wait it’s fine but could be better, it’s a tool after all that bike!

    Unfortunately, you are probably right. As much as my wife and I like the wireless gearshift I built into our bikes, I would regret it if wired electronic circuits became more expensive in comparison to wireless or
    even worse, became a thing of the past. Wireless is perfect for our use
    case, but not for any use case.
