Retro Rescue: Scott RC-703 SPD road pedals 

These came on the Colnago Tecnos I bought recently, but I’m pretty sure they weren’t original spec.

American pedals on an otherwise fully Italian road bike doesn’t seem right.

They’re early SPD, so different the modern version of the system and I have no shoes that work with them.

So I have no use for them at all, but can’t leave them dirty and unserviced, right?

Used to seeing daddy fixing stuff, this time my daughter wanted to help out.

Then a bit of WD40 always seems to help…

Transformed! Actually, on camera they look kind of the same…

Oh well, at least we did something “useful” on a rainy Sunday, and hopefully inspired my little one to repair stuff in future 😁

India does love the bicycle 

I almost bought this Hurricane indian made  gents town bicycle, with rod pull brakes, but… I just don’t have the space and common sense got the better of me.

Still, I did get some “Cycle” brand matches and sandalwood incense sticks recently in Mumbai. They smell so strong!

Not sure of the connection to bicycles though… 😂

Retro Rescue: Shimano Dura Ace PD-7401 pedals 

I recently picked up these pedals for my mid 90s Colnago, so I could use my regular riding shoes and cleats, without changing over the pedals from my regular bike (Lemond Chambery 2007) each time.

Those that came with the Colnago were made by Scott and weren’t compatible with my cleats. Also I suspect not original spec. I can’t imagine Colnago using Scott pedals when everything else on the bike was Campagnolo.

From the seller’s photos, I assumed these were regular, well used, Shimano SPD pedals.

Of course, as soon as I opened the box, it was apparent they were something else, and some googling showed they were mid 90s, top of the line, Dura Ace, Look-compatible pedals.

It seems this was one of the earliest quick release clipless Shimano road pedals, pre-dating road SPD, using technology developed by French company Look, based on ski bindings.

Shimano took inspiration from Look’s pedal design, and presumably then improved on it for SPD. Once I find some compatible cleats, I would be interested to test how they compare.

The pedals were pretty scruffy when I got them, so the first thing was a quick clean. A bit of degreasing as well to get rid of the oily spots, trying not to get any WD-40 in the pedal spindle.

It’s best not to dissolve the grease that’s already in there. Particularly as the pedal spindle can only be removed with a special tool, which I don’t have.

The pedal body has a small panel which can be removed with two torx T10 bolts.

Inside is simply a steel axle around which the cleat lock mechanism sits held in tension by and large special shaped spring, connected to the tension adjustment bolt accessible from the underside of the pedal.

This looked clean enough that no maintenance was really required. There is a very small gap between the cleat lock mechanism and the pedal body, through which small bits of road dirt and water could get in. That said, the outside of these pedals suggests they had a hard life, yet the inside is remarkably clean, so it works well enough.

I would like to degrease and regrease the spindle, though without that tool for the octagonal lock nut, it’s not really possible to do so. It turns freely enough, maybe not as fast as I would like, but it’ll do for now.

Overall this is a neat, simple and modern design and it seems things haven’t changed much, as modern pedals are essentially identical.

Anyone know what cleats will work with these?? I’m keen to try them out.

Bianchi Theridion

Now here’s an odd looking mountain bike. 


The jaunty angle of the saddle and the plastic bag make this look like a tired commuter, but given it’s pedigree, original components and bizarre frame design, surely this is a diamond in the rough?

What do you think?

BMC Fourstroke FS04 (update 3)

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! 

Velobrico workshop: SRAM X4 rear derailleur 

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. 


Looking past first appearances, a number of components, including the derailleur, looked salvageable. 

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. 


Like with most things, putting it back together again is considerably less intuitive than taking it apart!

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. 


Some adjustment to the derailleur cable and a liberal dose of WD-40 on a rusty chain and cassette later, and we’re good to go!

Total bench time, maybe 40mins on a rainy Sunday afternoon?

Oh yeah

Finally the wait is over. I bought my first Italian bike. 

And what a bike! 

Can’t wait to pick it up…
