Now here’s an odd looking mountain bike.
What do you think?
Yesterday I was in Bangkok. Like Mumbai, not a city you might think ideal for cycling, but I was surprised to see it heading in that direction.
My recollection of Bangkok was more like this.
I was surprised to see they have an urban bike share system. Great stuff. I wonder how popular it is.
Then I came across a Bubble Pirate. “What’s one of those??”. The Bubble Pirate turns out to be a man by the name of Sandy with an interesting story and a penchant for spreading joy. Read more here.
He traveled to Bangkok from Singapore, where I also once lived, over 3 months, enchanting families with bubbles along the way.
Just before sunset in the evening light, the colours in the bubbles were so vibrant.
Sandy’s journey will continue, so who knows where you might find him next.
I also spotted a beautiful vintage Thai-made Rama (the name of the Chakri kings of Thailand) bicycle at the Chatuchak weekend market (not for sale). I would guess this dates from the 30-40s. Beautiful condition and apparently complete and original.
That’s a lot of surprises for one day. Bangkok never fails to amaze.
I was in Mumbai yesterday.
Given the traffic is so heavy and slow, the commute time by bike is probably equivalent to that by bus or car.
Life expectancy would be significantly shorter though…
This man deserves a medal. Or even better, a helmet and some lights!
After looking for a number of years, an opportunity presented itself and… I just bought my first Italian bike!
Here’s the photos from the advert, mostly looking complete and in sound condition.
The Tecnos is a steel framed road bike, made by Colnago in the second half of the 1990s and I understand to be the lightest steel frame they ever built. The tubing is made by Columbus, with a special alloy, made only for this bike.
I presume this was one of the last frames to be made in Italy before work was outsourced to the far east. The frame is painted in Colnago’s Art Decor style, a somewhat psychedelic, vivid paint scheme, done entirely by hand. It’s really something special.
On getting it home, for once I managed to contain my excitement and took some close-up photos before I did anything to it, though I was itching to get to work!
The bell really adds to the look, and the reflective tape on the head tube.
A little cable housing rub on the head tube.
Damaged chrome on one fork leg, not good.
Rims are sound and true, no cracks.
Really nice lug work.
The other fork is fine.
Some pretty spectacular paintwork. You either love it or you hate it!
The paint was a surprise. I expected it to be glossy, but it’s actually a matt, soft, slightly tacky finish. Quite unusual and I have never seen this before.
Chain rings are good, no shark teeth.
Quick release put in the wrong way round.
I spent the rest of the day washing it, removing stickers, the bell, the saddle bag, the lock, and various bits of sticky tape.
…and servicing the gritty and grimy rear derailleur, cleaning the chain, adjusting the saddle, brakes, installing some new Michelin Classic tires and switching out the pedals to Ultegra SPDs for a test ride.
As there’s still some more to do, I’ll keep the photos for another day, but I took it for a shakedown ride on Sunday and it greatly exceeded expectations.
My overwhelming first impression was how smooth it is. Very little road vibration, smooth shifting, everything is tight. At speed it just flies with very little effort. Gearing ratios are little odd, and didn’t give us much range as I would’ve expected for a triple chainring, though climbing was no problem. Steering is very precise, without being twitchy and nervous. I had never ridden Campagnolo before, so the shifting took a little getting used to, but it has a good, positive, clicky feel.
It’s amazing how well this 18 year old bike rides, a real cracker.
Watch this space for updates and photos of the finished project!
You may have been wondering what happened to the BMC mountain bike restoration project I started a while back.
Like many projects it got to the “nearly finished” stage and sat there for a good six months causing a nuisance to the family.
Good news that it’s now moved on to the “basically finished” stage…
It was cleaner, but is now dusty from riding. So apologies for the photos, but it’s great that it’s rideable!
On an earlier test ride, I noticed the left pedal crank creaked on the downstroke, which it didn’t on my first test. This suggested a worsening issue, so I inspected further.
Anything other than a smooth bottom bracket/crank is bad news. A lot of torque goes through there, plenty to cause damage pretty quickly if not addressed.
I found an allen key large enough to remove the pedal cranks, and discovered a Shimano Octalink bottom bracket. This is the first Octalink system I have owned, with all my older bikes having square taper BBs.
I also found the non-drive side (left) mating splines to be slightly chewed at the end. Apparently this is common with Octalink systems, and happens when the crank arm isn’t perfectly aligned, prior to screwing the crank arm bolt back on. So, as I had never removed it, this damage was done by the previous owner, though it seems odd it didn’t creak on the first test ride.
In short, the crank arm is toast and needs replacing. The BB itself is in good condition and runs smoothly, so is perfectly reusable, but as Octalink is no longer common, finding replacement crank arms was an issue. Basically I could only find a new Alivio set which would be fine, but for the fact it wouldn’t add to the overall look of the bike.
After a little cogitation, it dawned on me an alternative might be right under my nose…
Some time ago I rescued a binned Steppenwolf hardtail MTB frame with some components still attached, including XT cranks and a more modern external bearing BB. Why not see if it’s the same width as the octalink BB?
Lo and behold it was, so I would theoretically be able to replace a Deore LX crankset and Octalink BB with an XT crankset and modern external BB, at no cost. Not bad at all and 100% eco-friendly.
One problem. Don’t have the right tools!
As systems evolved, so the tools needed to work on them change. Though this a consequence of welcome technological innovation, it poses something of a challenge for the home mechanic.
A regular crank extractor tool doesn’t work with an Octalink BB. To remove a BB on a vintage bike you need a hook spanner, an Octalink BB needs a BB removal nut thingy (like for a cassette but bigger), and an external BB uses another type of large spanner with slotted splines. Consequently, you often need different tools to work on various bikes.
The bike shops near me aren’t really set up for the home mechanic, so buying tools is interesting and expensive. Apparently, in Switzerland, folks like to get other people’s hands grimy instead of their own (which probably makes sense).
As I quite enjoy grimy hands and torn knuckles I set about looking for tools and stumbled across a sale on Chain Reaction for an 18 piece toolset, for 50CHF delivered, including some tools I had already, everything I needed for this job plus a couple of extras. Pretty good deal, and arrived within a week.
Once the package hit the doormat, like a child on Christmas morning I ripped it open and within 20mins had replaced and upgraded BB and crankset and chainrings to higher spec parts. Great!
The toolset is made by X-Tools, and though I was hesitant about quality given the price, I am quite pleased.
The “new” drive train all works perfectly and it’s always most satisfying to complete an long term unfinished job.
So the moral of the story is, if you can salvage used parts, do so. You never know when you might need them and they’ve often got lots of life left.
Secondly, always invest in (quality) tools. Even if technology changes, and you only use them a few times, they pay for themselves quicker than you think.
Also, that which is new today will be vintage tomorrow, so there will always be more bikes to work on!
A while back I picked up a trashed Specialized Hotrock kids bike. The frame looked sound but everything else was pretty far gone.
This bike would need far more workshop time than it’s replacement value, so it’s owners rightly binned it and moved on. But it’s a decent size for my son’s next bike, giving me enough time to fix it up before he can ride it.
Among numerous other issues, the derailleur hanger was bent, chain broken and derailleur was in a sorry looking state.
I straightened the derailleur hanger with a pipe wrench plier and then set to the derailleur itself.
It’s pretty straightforward to service a derailleur, remove, clean, degrease and regrease jockey wheels then reinstall. But it’s a bit of a dirty job, so rarely gets to the top of the DIY service list.
After getting it completely wrong, I removed the jockey wheels again and correctly rerouted the chain, using the smallest cog and chainring to give enough slack to work with.
Total bench time, maybe 40mins on a rainy Sunday afternoon?
