The Current Fracas Around Hookless Rims

Generally I like to keep up to date with advances in cycling technology. This includes increasing gear numbers, adoption of disc brakes, carbon fibre frames and parts, electronic gears and the like. I like to think I hold views on bike tech that have an appropriate balance between reality and fantasy.

For example, disc brakes seem to me to be welcome because they offer superior braking in some conditions, such as heavy rain. Given that braking efficiency on a bike is mostly down to friction between the tyres and the substrate (in my case tarmac), I've never found disc brakes to have braking performance superior to rim brakes. And I would not like to be on a cycle tour and have problems with a hydraulic brake system.

Cervelo P3 Test Ride

I've posted a few times on my modifications to my set up of the Cervelo P3 (most recently on my home brew eTap wiring). The recent mods over the last few months include:

  • Fitting a secondhand pair of Aduro tri-bars with the high arm pad extensions
  • A complex rewiring of the 11-speed (i.e. non-AXS) SRAM Red eTap gearing
  • Replacing the inner tubes with Tubolito PFU tubes
  • Sorting out the computer mount to accept a front light
  • Replaced the ageing big chainring.

I've been meaning to take the P3 out for a test ride to make sure all is in order, and with my first event of the 2024 season fast approaching (the Port Talbot Wheelers 2-up 25) I decided to do so this morning.

My Websites

 

Support for Joomla version 3 ceased in August this year, and I'd been working on ensuring the three Joomla sites I maintain were upgraded to version 4 in advance of that. What I realised in doing that was the enormous amount of cruft I'd accumulated over the years, especially with the North Bucks Road Club website. One of the issues is always that of finding a sympathetic template, particularly where user access on mobile devices is concerned.

SRAM eTap wiring (being the second part of remodelling the Cervelo P3C)

In which I test (and implement) some alternative wiring possibilities for SRAM eTap gear shifters

The SRAM eTap Aero groupset was released in 2015 with a version aimed at road bikes where the gear change controls were switches in the brake levers, and which communicated with the front and rear derailleurs via a proprietary wireless signal. For time trial bikes, the eTap aero was released, where switches mounted on the aero bars were wired to a "blipbox", which wirelessly relayed commands to the gear mechs. Typically, one would set up a pair of switches (the "blips") on the base bar and a second pair of switches (the "clics") on the ends of the aero extensions. The blipbox has four sockets, two for upshift and two for downshift - each clic or blip switch is connected via one socket. The blipbox also has some buttons for shifting. The annoyance there is that the size of the blipbox makes it difficult to tuck it away in the time trial frame.

My Venerable Hed H3 Trispoke Wheels

Hed H3 wheels are  probably Team Grumpy’s go-to wheel - they are pretty close to being indestructable (but not invulnerable) - they aren’t likely to go out of true as there aren’t any spokes to break or lose tension. 

In use, I’ve always found them to handle well except in the windiest of conditions (see for example the 2018 edition of the Duo Normand when I ended up using a regular spoked wheel). In comparison to very deep rimmed spoked wheels, they seem to be more of an all-rounder aero wheel for time trialling.

My Current Power Meters

In which I review the power meters I've been using over the last few years. All of these seem to be accurate and consistent in their data. This is a brief review of the four systems I currently use - and to cut to the chase, of these four power meters, which would I recommend as a power meter on a new bike build?

Given that two of these power meters are discontinued, the choice comes down to the SRAM Red chainset or the Assioma Duo pedals, and from the viewpoint of easy transfer between bikes I'd recommend the Assiomas (which can also be bought in a version to be fitted to Shimano pedal bodies). I should add that all four of these power meters have been absolutely faultless in use.

Brooks B17

A supremely comfortable saddle for touring use. Possibly my oldest bike component that is still in use (even if only occasionally).

During a recent garage clearout, I unearthed this saddle. It's clearly seen better days - the surface of the leather is a bit cracked and the rivets are a bit green! These photos were taken after I applied some Proofide.

The eTap Blipbox and the Cervelo P5

In which I grab the soldering iron and splice together wires and plugs to place the 'brains' of the eTap system deep in the bowels of my TT frame!

Earlier this year, I travelled to Wales for a Team Grumpy reunion of sorts, in the form of a 2-up team time trial. This was a ‘sporting course’, so I took along my Cervelo P3, currently equipped with 11-speed eTap Red gears. By the time the bike had been in and out of the car a few times, one of the blipbox ports had stopped working (this happened before, with the P5).

Pedals - Speedplay X R.I.P.

For the last 6 years or so, my favoured pedals have been Speedplay X series pedals. I’ve enjoyed using these pedals because they are light (though the cleats are heavy, as they contain the clipping mechanism), have a remarkable amount of float and they offer dual sided entry.

Speedplay has been bought by Wahoo - there’s a detailed acount by DCRainmaker. Essentially there were a lot of rumours that this may lead to a Speedplay based power meter, though since the acquisition, there’s not been a lot of noise.

SRAM eTap Aero – Part 4

This is a longer term follow up to the previous postings on my experiences with the SRAM Red eTap Aero derailleur system. I was an early adopter, buying the eTap aero kit in early 2016. A bit of a glitch occurred in November 2016 when the BlipBox malfunctioned, and this was resolved later that winter.

Until recently, the system has functioned flawlessly, and indeed I've liked it so much I sourced parts (mostly via eBay) to fit out my P3C bike with it as well. As you'll see in this report, I've had a recurrence of the BlipBox issue, and this caused me to look into buying a replacement, which turns out to be not only expensive, but near-impossible through my usual retailers.

As maintenance-free as possible…

A few months ago, I reviewed the Shand Stoater bike that I’d bought as a problem-free commuter bike / tourer / winter bike - it’s equipped with a Rohloff hub gear and a Gates carbondrive belt rather than derailleur gears and a chain. Since then, I’ve used the bike a couple of times a week as a commuter (the rest of the rides to work are on a tandem), and out twice a weekend for club runs and the like. In that time, the only mechanical problem I’ve had has been a repeated puncture caused by a tiny black thorn in the rear tyre - so small and black my ageing eyes couldn’t spot it. Other than that, it’s been great fun to ride - and even dealing with a rear wheel puncture has been a lot less messy than with a chain.

A New Bike for 2019 - Shand Stoater

One of the things about commuting and touring that can be a bit irritating is keeping the transmission running sweetly in the face of sometimes wet and horrible weather. In the past I’ve had rusted and worn chains, clogged derailleurs and so forth. A few years back we bought a new tandem from Thorn, a Raven  Twin, which was equipped with a Rohloff 14-speed hub. This has been really great, especially with a set of high quality KMC chains, which do resist rust quite well (recent SRAM chains rusted badly, though I can’t recall the model). I’ve particularly welcomed the ability to change gear when stationary, which seems to me to be important when riding a heavily loaded tandem.

Remodelling a Cervelo P3

This autumn/winter, I planned to refurbish my 2010 Cervelo P3. Over the last year or two, I’d gone from 9 speed to 11 speed Dura-Ace, so that I could swap wheels with my main time trial bike, a Cervelo P5, which is presently equipped with SRAM eTap kit and concealed Magura RT8 hydraulic brakes.

The main intention of the remodelling was to reduce the amount of cabling exposed to airflow on the P3, and generally make the bike a bit sleeker. The P3 is quite a bit bit lighter than my P5 bike, so I have the intention of using it on rather more undulating courses where its monstrous top gear is rather useful on long descents.

Astwood ’20’ 15/9/18

I realise I haven’t blogged too often about time trialling (and cycling in general) this year. That reflects considerable personal and work-related things getting in the way of (a) training, (b) racing, (c) cycle touring and (d) blogging.

At this point, I could note that our summer cycle tour had been planned to include many Outer Hebrides. It went seriously awry when a road accident delayed us while driving to Oban for the first ferry, which we subsequently missed by seconds. As it turned out, this was a good thing as Storm Hector blew in later that day, closing down the ferries we’d planned to use in the tour. So that was that.

Norlond '10' F15/10 5/5/18

So now I've started, I'll continue!

This event was held on a spectacularly sunny and warm afternoon. I rode over to the HQ in Lidlington. This was a pleasant ride marred only by a puncture  just after riding through Ridgmont. I only got a little mucky while changing the inner tube, but of course the little mini-pump only gets the tyre pumped up to a 'get you home' pressure, and it wasn't until I got to Lidlington that I could pump it up properly with the help of a borrowed track pump (thanks, Trevor).

A visit to the F. T. Bidlake Memorial

I live and time trial in the London North District, where the flagship course over many years has been the F1, which uses the A1 dual carriageway (formerly the Great North Road). The Great North Road has been significant in the history of English time trialling over the years. Nowadays, events on the A1 in this area are restricted to the stretch of road between the Black Cat roundabout and the Baldock interchange, where the A1 becomes the A1(M) and beyond which bicycles aren't permitted. When I first moved down here, things were different, with time trials reaching thr Alconbury interchange - over the years, I've ridden a variety of course permutations - the majority of which are based on a start point near Tempsford (and usually using the Stuart Memorial Hall in Tempsford.I'd been aware of the F. T. Bidlake memorial near Sandy for some time, but until today hadn't actually visited. There's a brief biography of Frederick Thomas Bidlake (1867-1933) at wikipedia - put briefly, his role in English time trialling was significant.In the 1890s, cycle racing on roads was threatened following an incident between a couple of racing cyclists (Bidlake and a friend, pluse their pacers) and a lady with a horse which, startled by the cyclists, reared causing the cyclists to wind up in the ditch. Despite the fact that most damage was caused to the cyclists, complaints to the polices about cyclists' behaviour led to concerns that cycle riding on roads might be banned - at the time there was some pressure to amend to Highways Act. To forestall this, the National Cyclists Union banned racing on the road and insisted competitive cycling should only take place on tracks (known as 'paths' in those days).Not everyone agreed with the NCU's decision, and a rival organisation was set up - the Road Racing Council - and Bidlake organised a road race on 5th October 1895 which essentially used the time trial formula used to this day. Though it's not true to say Bidlake invented time trialling, he was one of those who codified the sport.Bidlake worked in a number of sports, including the Scheider Trophy for seaplanes in which he was timekeeper. Ultimately, Bidlake died three weeks after a fall on Barnet Hill due to collision with a car. The memorial was erected in 1934 after a public subscription. It's quite a modest affair, with a box hedge enclosing a triangular plot near the A1 at Sandy. Here's a Google Maps link that shows where it is.[caption id="attachment_4097" align="alignnone" width="1000"] The Bidlake memorial garden - in a rather inaccessible location[/caption]There's a stone pedestal that looks to have had something cut off - from the Wikipedia page, I think it formerly supported a sundial - with a legend "He measured time".[caption id="attachment_4096" align="aligncenter" width="563"] The pedestal that formerly held a sundial[/caption]Above a bench, there's a plaque inscribed

THIS GARDEN IS DEDICATED TOFREDERICK THOMAS BIDLAKEA GREAT CYCLISTA MAN OF SINGULAR CHARM & CHARACTERAN UNTIRING WORKER FOR CYCLISTS1867-1933

The bench itself is a commemoration of Bidlake's colleague George Herbert Stancer, and indeed Stancer's ashes were scattered in the the memorial.

Port Talbot Wheelers 2-up '25' 11/3/18

Team Grumpy assemble for two regular events each season - aside from the Duo Normand in September, the team generally opens the season with a ride at the Port Talbot Wheelers 2-up '25' in early March. 2018 was no exception. This year (as last year), the event was shifted to the fast R25/3H instead of the more rolling course usually used, owing to roadworks.

The team had the usual preparation of curries, beers and crisps in the preceding days, and after a little worry about the weather (there was heavy rain the day before and on the day after the event), was more than a little relieved to have dry conditions. There was some wind, of which more later.

Astwood '10' 3/3/18

It's been a while since I updated this blog. After the 2017 season finished, I began my usual winter training programme - after a short break I started a build up towards the New Year's Day '10'. Unfortunately a series of events significantly more important than training impacted on me, and my training suffered, and I did not ride the New Year's Day '10' for the first time in many years.I'd been looking forward to the opening event of the North Bucks Road Club time trial series. This was a Saturday morning event to which we'd hoped to attract newcomers. Unfortunately we have had a modest snowfall, and the event got cancelled. So, not much of a blog entry. Perhaps there will be a bit more action next weekend!In the meantime I discovered that the left hand Speedplay pedal on my main time trial bike (which hasn't been ridden since the Duo Normand) has pretty much seized up. I've tried injecting copious grease but that doesn't seem to have sorted the situation, which is sufficiently serious that I have taken the extraordinary steps of resorting to eBay to buy a set of replacement bearings. Hopefully they will arrive in time to overhaul the pedals before next weekend's time trial (which is the first open event of 2018 for me -  a 25 mile 2-up).

Stoke Hammond '10' 31/5/17

After a couple of weeks without racing (and indeed a week off the bike), I turned out for the club '10' on a sunny evening at the end of May. I've been getting a little concerned about the downturn in my form lately, which is partly why I took a bit of a break from training, so I was keen to see how this evening's '10' would go.I was quite a late starter in the field, and it was clearly quite a nice evening for a '10'. The starting stretch was OK, I avoided overcooking it at the start. Sadly, once I turned left up the DC drag, things went a bit pear-shaped. I clipped the edge of a large pothole (the whole course suffers from too many road defects), which bounced out my bottle, and caused me to run into the grassy verge. I was rather exasperated, at this and decided to get off to retrieve the bottle and check the bike was OK. I noticed that the impact had loosened the ratchet on my left shoe! So, by the time I'd got sorted, given the bike a quick once-over, and tightened up my shoe, I'd lost about a minute and 20 seconds. Despite that, and the fact I was having to get going on an uphill stretch, I decided to complete the course.After my altercation with the pothole, I was acutely aware of the remaining numerous potholes, which I managed to avoid. Also, there were no traffic related holdups! I finished with 24:40, not too shabby given the disastrous ride!
