Cermanic Speed is the future of road bike drive trains….WTF??

Dear Rouleurs,

MMT is still grappling with time poverty and sleep deprivation. With Bubba Mark 2, only 3 months away, MMT is beginning to think this will be a tough year. As harbinger of things to come, MMT watched Richmond’s AFL premiership hopes for 2019 nose dive last week. Alex Rance hobbled off the MCG with a season ending ACL injury. So AFL may not be a source of solace for the coming winter either. MMT digresses.

When MMT feels this out of sorts, thinking about buying a new bike always cheers MMT up. In the deep contemplation of road vs commuter vs gravel bikes as alternate replacements for MMT’s Venerable Wilier Laverdo, He re-discovered last years announcement from Ceramic Speed, a Danish bike components company.

Sometime in September 2017, ceramic Speed released a prototype road bike that contained a radical new drive train. This drive train based on a drive shaft rather than a chain meant that its power efficiency could reach 99%. That’s damn impressive and could give a rider a very significant speed advantage over his chain equipped competitors.  According to Ceramic Speed, a standard chain based drive train, like Shimano Durace has a maximum efficiency of 97%.

All of this is achieved by a pinion style drive shaft system. A total of 21 bearings play a crucial role in the functionality and efficiency of Driven. The bearings transfer torque from the front ring through the drive shaft, then onto the 13-speed rear cog.

Engineering aside, it looks amazing, like something out of a science fiction movie. MMT …sooooo… wants a bike that has this. No doubt this will cost big bucks when its eventually productionised and available to mug punters like MMT.

MMT could imagine Dave Brailsford, Manager of the team formerly known as Sky, signing up for this. One wonders how Shimano, Campagnolo and SRAM will respond to this incredible looking piece of engineering. All of this speculation cheered up MMT no end.

Until Next time, Ride safe


Product Review: Shimano R107 shoes and 105-5800 SPD-SL Pedals


Dear Roulers,

Nearly three months ago, I purchased a shiny new pair of Shimano riding shoes and pedals. I had previously been riding around on Shimano MOV76 MTB shoes and SPD pedals. These have been awesome and I’m still using them for commuting. As beginner’s kit, they greatly assist the learning process of clicking in and out at traffic lights, whilst providing reasonable connection to the bike. SPD pedals are heavy-ish but nearly indestructible. Within 6 months of using them, I had converted every bike I own to SPDs.

However, I felt ,that in the quest to go a bit faster and a bit longer I, needed to try some new kit. I’m still procrastinating over rims but I felt an upgrade to new pedals and shoes would be a sound investment. So I bought a black and blue pair of Shimano R107s and a set of Shimano 105 SPD-SLs.


I’ll start with the Shoes.

Shimano R107 Road Shoes

The shoes are fairly light weight, quite stiff and IMHO look pretty good. I got them for what I consider to be a bargain on a internet bike shop at the princely price of $120. I’ve seen them in Melbourne based bike shoes for $60-$80 more. I ordered a size 42 which was the same size as the MOV77 and noticed that the fit is smaller and narrower. In hindsight I would have purchased size 43 to allow for winter socks and a slightly less constricted feel. The good news is that shoes are very well vented and cool. The bad news, at least during the cooler months, is that the shoes are very well vented and my feet are becoming ice blocks. I’m seriously contemplating overshoes to keep my feet dry and warm.
The only annoying gripe that I have is that Shimano don’t provide additional cleat screws and plates. I managed to lose one early on and fortunately the the kind chaps at City Cycle Galleria gave me spares. Overall I’m really impressed with quality of the shoes.

Shimano 105 5800 SPD-SLs

I bought these pedals on the strength of many outstanding reviews and this one in particular convinced me that this was the right option for the type of riding that I do.

They are a little tricky to fit, you have to use an allen key to tighten them into position. I now have a useless Park Tool pedal spanner 🙂
So the SPD-SLs….oh man I had no idea how difficult it is to clip into ‘Look’-a-like pedals. My initial ‘strike rate’ was about 25% and I was losing 30 to 45 seconds of time at traffic lights trying to clip in. Also, I had to unlearn the, now unwise, habit I had of resting my not clipped-in, right foot on the pedal. The combination of new slippery carbon fibre shoe sole and beautifully smooth pedal do not allow the rider to put any power into the reverse side of the pedal.

After my first couple of rides, I developed a bruise the size of an orange on the back my right calf muscle. I would miss the clip in or attempt to rest my foot on the pedal and have the crank spin round and smack the pedal into the back of my calf….ouch!!! I’ve figured out my own method for clicking in and I’m somewhere near 75% first time contact.

Now that I’ve been riding on them about 10 weeks I think I can say they were worth buying, although I haven’t necessary achieved the increase in speed that I was hoping for. I’ve fitted the yellow cleats in a neutral setting and I’m still fiddling my fit on the bike to find the best way of using them.  I’ve read that the blue ones might be better and I’ll try these next.

Finally its 3 more sleeps to the Tour De France and I can’t wait for 3 weeks of sleep deprivation 🙂
