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

Oh no, oh no, oh no….my Zonda rims are cracked

Dear Rouleurs,

MMT had a dreadful trip to his friendly neighbourhood bike shop, Good Bikes’ last week.  MMT’s venerable Wilier was making a few awful noises from the vicinity of the bottom bracket.  May be it needed replacing as it had been ridden on for nearly six years.  Similarly the left pedal was behaving very weirdly under power.  All in all, it seemed high time for a service.

So MMT rode his Wilier to work and dropped the bike off.  A few minutes of explanation ensured.  The mechanic, Nathan, was advised to ring me if the price of repairs was exceeding $300.  Nathan called MMT a few hours later and his news left MMT aghast.  Apparently the rear rim was showing signs of cracking and needed replacing…..crap….Keep in mind that these were the $800 Campagnolo Zondas, bought just over 2 and half years ago.

Fortunately, MMT had kept the original Fulcrum rims.  MMT had spent a frustrating Saturday afternoon, a few weeks ago, fitting spoke reflectors and had intended to use these as his winter wheels.  So the Wilier stayed at the shop, until the old rims were retrieved and fitted. Nathan showed MMT the cracks and MMT was horrified at what he saw.

MMT reckons he’s done about 15,000km on these rims and can’t believe how these stress fractures have occurred. For starters, they are all on non-cassette side of the rim. One of them has cracked clean through, with clear daylight visible. MMT can only shudder at the thought of what may have happened had the spokes given way entirely.

MMT is not a happy camper…

Until next time, ride safe.

Marv’s August Ride Log

Dear Rouleurs,

August was another month messed up by YAFF – yet another f&%king flu, at the start and end of the month.  Given that August was a five week month, that lost time really hurt.  Looking out the window at clear windless mornings while coughing up gunk off my lungs, just pissed me off. Repeated trips to the doctor, a chest x-ray and couple of courses of antibiotics still haven’t managed to get MMT back on the bike.

As a consequence, MMT only just scraped past his monthly target.  Boooooo!!! MMT hates YAFFs.  Overall I’m still about 695km ahead of the weekly accumulated target as of the 2nd September. MMT is hoping for much better health and progress in September.  So here’s my monthly graph.  Its distinguished by flatline totals at the start and end of the month.

In yet another statistical quirk, while the monthly kilometres was down, MMT’s average suffer score rose from last month’s 36 to this month’s 39.

My ride log is found here.

Until next blog, ride safe.

Marv’s March Bike Log

Dear Rouleurs,

March an awesome month for cycling.  MMT clocked up 753.29 Km and beat his old record by some way.   The weather has been excellent, with light winds and mainly sunny conditions.   MTT’s  log and stats can be found here. This puts me over 200 km ahead of my monthly goal of 542km.

The big numbers are longer solo and RCC training rides.  March 26 was the date MMT did the MS Cycle 50 km event.  Here’s the matching suffer score graph for the above graph.

Apparently I suffered more this month than the previous two, despite having no big events in March.

Until next blog, ride safe.
