So my next blog post was meant to be on how the brake install went. The good news is the brakes work great - I’ll get into more details on that later. HOWEVER while riding out to somewhere nice where I intended to take some nice picture I had a bit of an incident - so lets talk about that first.

I split off the Bay trail to grab some coffee, eat some food and slap on some sun screen. While attempting to rejoin the bay trail I found myself a little bit confused as to the route and ended up on a footpath rather than a shared path. I spotted where my turn was meant to be and while focused on that it hit me. Well more specifically I hit it. A low hanging branch.

I’m not sure if I didn’t see it, correctly identify it’s height, or if I stood up to ride, but I hit it - likely at around 12km/hr. Lucky I wasn’t going faster. Next thing I know I was on the ground wondering wtf just happened. I remember seeing my Garmin count down from 6 seconds (I believe it starts at 30 seconds so there’s 24 seconds somewhat unaccounted for). Since I was on the ground, still processing everything and unsure if I was ok I let the timer count down.

This triggered an SMS with location details and starts live location sharing with my partner. After I had worked out that I was somewhat ok I stopped the incident on Garmin, and sent a message to say I was fine.

Since I’ve had my Garmin Fenix 6S Pro I’ve recorded 585 activities and only 2 other times have I had incident detection trigger when I was fine. One time was when my watch band broke, and the other was mounting a curb and coming to a hard stop. Both of these are some what reasonable that incident detection triggered.

I am very glad for this system, as had I passed out it would have been over half an hour before someone would otherwise notice (this is the time I sat next to my bike recovering)

Given I was riding as an alternative to running for recovery purposes I’m not happy about the incident.

So with that out of the way, let’s talk brakes.

Inline brakes

These were a breeze to install. I’m missing some end caps here and the grip tape ends is a temporary thing while I work everything out. The hardest part was working out how to mount my light given all the space is taken now by the brakes. I have end caps in storage but I wanted to test everything out first.

First off, the myth that inline brakes make the system spongy is clearly false. If you go back to part 1 of this series you’ll see that the brake cable is uninterrupted for inline brakes. There is no reason why adding inline brakes would make the system worse. My suspicion is that people think that inline brakes are spongy is that they are often installed on brake systems that are already spongy. The inline brakes themselves have a lot of pull - keep this in mind.

While I still haven’t gotten used to their presence, I have already adjusted my riding style. I’m sitting in a much more comfortable position while casually riding and not having to get into the drops to slow down. This is great in the city. I still find myself sometimes moving my right hand down to the original lever out of habit, but a lot less now. Tight corners are now much easier to manage.

And the back brake is getting a lot more use now - since I don’t have to get into the drops I now apply a lot more even braking. Where this is extremely useful is red lights and other stops. Previously I would brake to slow down, stop braking, move my hand to the gear lever to move into the lowest gear, then move my hand back to brakes to come to a complete stop. Now I can use my rear inline brake while changing gears with my other hand and perform the action all at once.

Dual pivot brakes

I ended up with the Tektro R559 dual pivot long reach brakes. The frame / wheel combination I have means that I’m on the higher limit of typically short reach brakes and the lower limit of typical long reach brakes. If I ever buy a new set of callipers again I might try to gamble on short reach brakes. Currently though the long reach brakes do give me the option to switch in a 700c wheel….

So while you can sometimes pick up traditional nut style brakes, it’s more common to find recessed style. These have a shorter shaft and a long recessed nut that is used to hold the brakes in place. I purchased these brakes knowing that the recessed style wouldn’t fit my bike out of the box.

There’s some solutions to mounting these brakes though. The most common is to drill out the back hole (usually using a right angle drill for the rear brake) to allow the recessed nut to fit.

The other option that’s also sometimes available is to use the front brake (has a longer shaft) on the rear brake. How do you install the front brake then? For me I was lucky enough to be able to fit the nut through the bottom of the forks. This only gives half the mounting distance than typical however I believe it’s plenty.

For both the rear and front shafts I found I could only use one of the wedge locking washers, but once again - I feel like this is plenty. If this doesn’t provide enough friction the outcome is that the brakes could become unaligned and start rubbing while riding. It’s not catastrophic failure.

I’m happy with having the brakes mounted this way as it means I don’t have to make permanent changes to the bike frame and if I want to I can reinstall the original brakes.

Other changes

I’ve installed some new toe cage peddles. I was a bit nervous installing these again as they can add a certain amount of risk in casual riding, but I’ve been pretty happy so far with them. They certainly look the part. Unfortunately the NOS I purchased, the grease had gone bad. I’ve tried my best to get some oil in there, but I’m going to either flush out all the grease somehow or do a rebuild. Neither of which I can do easily right now.

Lastly I’ve updated my Kmart bike lock to ABUS. Hopefully no one steals my lock. This lock feels very over engineered but I like it. It’s spring loaded and pops out when you unclip it.

That’s all the upgrades I want to do for now. Sometime next year I plan to strip all the parts off, de-rust, de-paint and give it a brand new paint job.

I’m currently waiting for my bike parts to arrive today, but in the meantime I thought I was explain to y’all the plan.

JSON is my road bike. I use it to get to many things. It now gets very regular use, sometimes short rides, sometimes ride that I consider long. JSON is a vintage road bike, I don’t know when it was manufactured or by whom. Given it has Suntour 7 derailleur I’m guessing mid 80s. While these bikes are amazing (please try one), given the age they do come with some design problems. The biggest has to be braking. While I like to keep things fairly original on the bike, given that I doing more and more city and busy area riding I want to make the bike a little safer.

Now the brakes work just fine on JSON. The major problem comes with where the brakes are. If your not familiar with road bikes, those curved down parts of the handlebars are called the drop bars. The idea is that when you want to ride fast you “ride in the drops” - that is move your hands to the bottom of the handle bars to get a lower position. In contrast if you want a more comfortable ride you might ride on the “tops” or like the picture below is doing riding in the “hoods”. The hoods in a modern road is the combination gear shift and brake controls - well the hood is actually just the cover on top….

I however don’t have a modern bike, so I can’t ride on the hoods. Even if I did ride on the sides I don’t get enough lever force to correctly apply the brakes. This means that if I want to brake I have to be in the drops. When I’m riding around the city or busy path ways I’m often sitting upright to get better visibility and stability at the lower speeds. At the moment I have to choose between being in the drops for braking, or upright for visibility and flexibility - often I end up riding in an awkward halfway position with one hand in drops and one hand not.

But how do you install an extra set of brakes when there is only one cable? That’s where the inline part works, but lets first look at how a normal set of brakes work.

I’ve tried to create a crude diagram of brake fundamentals for bowden tube brakes. A bowden tube is, well a tube. It has a wire running down it. If the tube is fixed in place at either end you can push and pull the wire and the wire will push and pull from the other end. The final part is some pivot points, so when you pull on the brakes it pulls some wire out of the tube, that pulls the wire down on the brake end which squeezes the brakes together. Ok I get how bowden tubes work, what does this have to do with inline brakes….

For inline brakes the brake levers connect the outside of the bowden tube. The actual cable is unimpeded and the other brake will work as normal. Hence the inline part. In this diagram the left bowden tube is physically attached to the lever arm behind, and while the right part of the bowden tube outside is connected lever arm on top.

When we squeeze these levers together like you would on a brake the two bowden tube segments pull apart, widening the gap between the two bowden tubes.

The wire has to remain the same length however it now has further to travel, so this causes the wire to pull on the brakes…. hopefully bringing the bike to a stop. I’ve kept the wire the same length in these diagrams. I’ve also left the bowden tube the same length as well as that can’t shrink - so if we created a gap in between the tubes, where does that length go? We’ve effectively lengthened the bowden tube. In the real world the bowden tube gets slightly pushed aside, you do need to account for the movement in the bowden tube when it comes to routing and taping the tubes.

Installing these takes up handlebar space. I’ve already moved my phone mount to the stem, however I might need to rethink my bike light.

Finally, lets talk brake callipers. While braking on JSON is fine, I do want to make it better. Especially when I loan out my bike to someone else to ride. It currently has its original single pivot brakes, and the springs are a bit worn. Coupled with wheels that are over due for trueing it can lead to a fairly mushy experience if your not used to it.

That’s the plan.

Last Sunday around noon I realised that I shouldn’t be sitting mindlessly browsing the internet when Melbourne for once had half decent weather. Normally I’d go out for a run however my body needed some good recovery time so I decided to go on a walk. (narrator: this adventure did not end up being good recovery time). I slapped on some sunblock and a hat and set off.

The rough plan was to go on maybe a 5-10km/~1hr walk. Enjoy the sunshine and river. That sort of thing.

Walking lets you take in the sights better. You get to see a lot detail than just jogging past. There’s no pressure, you can stop to take a picture or enjoy a lizard friend crossing your path.

I however became more and more frustrated at the amount of litter I walked past. Right next to the river.

I eventually found a cement mix bag blowing in the wind. That was it. I was going to take that bag and pick up every bit of litter I could find along the way. I was walking, I had all the time in the world, I may as well do something good.

It didn’t take long however to fill the bag. By that time I had reached the Collingwood Children’s Farm (I must stress, that this is a farm in which children learn farming. They do not farm children there). I found a staff member and traded the concrete bag filled with rubbish with a new cardboard bag. In hindsight I should have tried to keep the concrete as it held a bit more, but I need to dump the rubbish and this was the easiest way.

Now I probably should have turned back then, however I was enjoying being outside and the weather. So I kept on going, picking up rubbish, jumping into creeks to fish stuff out, digging out stuck cans and bottles from garden beds.

Along the way I found some interesting things:

• 4x Bicycle rims
• North Melbourne Rec center pass (seems to be Mifare Classic)
• A credit card
• A surprising amount of clothing
• Two different shoes
• A full bottle of hair conditioner
• Hand pump paint sprayer
• Menu log delivery bag
• Scaffolding tag

I think the things that disappointed me most though were:

• Energy gel packets (these are used for refuelling runners and cyclers on the go)
  • It was always the same brand - so maybe it’s just one arsehole that runs or rides a lot
• Dog litter bags
  • I don’t think I’ll ever understand this. People pick up after their pets, then leave the bag near the footpath. This is literally the worst.

The bags of rubbish kept on filling and I kept on going. Where I could I favoured bins I could sort recyclables out - however some councils seem to only have general waste bins. Better in landfill than in the river though. I ended walking 20km over 4 hours.

Probably the worst section was from Flemington Bridge area where the M2 covers the track. I had to walk past so much rubbish because I couldn’t fit it in my bag. I suspect this section could do with more public bins however my guess is that most of the rubbish is from motorist yeeting their rubbish from their cars. That appeared to be a common thing as anywhere road related had significantly more rubbish.

I don’t think it’s all doom and gloom for the future though. I found surprisingly few shopping bags in my travels. I was expecting to find more plastic bags along the way to increase how much litter I could carry between bins. Guessing the plastic bag bans have worked well then. A lot of what I did pick up was bottles and cans. With Victoria finally introducing the container return scheme today (1st November 2023 as I write this post) I’m hoping to see a huge improvement. Coffee cups however… I think we need to consider a ban on those.

For me this was an unplanned adventure. A lot of people got in touch with me after asking me to go watch Beau Miles. I since have, and their videos are worth a watch. He’s a little more planned with collecting rubbish and I think I should start thinking about improving my rubbish collecting strategy.

The plan that isn’t so much a plan

I don’t really do these long walks often. But maybe I should? Maybe next time I should consider:

• Garden bags for collecting more waste (ideally I want to grab these second - things like pool salt come in them are generally used once)
• Snacks and water - While there was water on the track, I didn’t eat or drink anywhere near as much as I should have
• Support bike with trailer - maybe I could run behind a bike with a trailer to hold more stuff - this is a bigger project though
• Maybe focus on a really bad area rather than a really long walk
• Plan out where to return rubbish to - ideally being able to recycle

If I’m just going out for a walk I may as well pick up some trash along the way. Maybe I’ll do this again sometime.
