NBRC Club TT (Beachampton 2 x 5 miles) 16/3/24

After all the recent dreary and wet weather, I was pleased to have a lovely spring day to ride over to Beachampton (a bit over 20 miles each way) for this club time trial, though there were many puddles and other mucky sections on the course.

Are TPU tubes worth it?

tubolito road detail 5 fixheightOver the last few years, a new material for inner tubes has surfaced - TPU or thermoplastic polyurethane. The first brand I noticed was Tubolito, though there are several available now.

Since late last summer, I’ve been trying Tubolito road inner tubes on my TT bikes and on my summer bike. They seem very light, and surprisingly air tight compared to latex tubes. I’ve only used road bike tubes, which come in a couple of weight variants and valve stem length. The two weight variants are the standard Road tube (coming in at a quoted 38-40g per 18-30mm tube) and the S-Road tube (coming in at 23g per 18-28mm tube). The S-Road tubes are for disc brake wheels only.

So are these fancy and expensive TPU tubes better than the alternatives?

Port Talbot Wheelers 2-up '25' 10th March 2024

240310 PTW 05 smallIn which Team Grumpy make a good impression by turning out in matching kit and bikes - but then disaster strikes!

Most years, Team Grumpy rides an early season 2-up team time trial to keep our hand in by brushing up our 2-up skills ahead of the autumn's Duo Normand. Since the apparent demise of the Duo Normand since the 2020 pandemic struck, these early season 2-up events have become an event in themselves, and this year was no exception. After a couple of evenings of food and beer we felt adequately provisioned for a 25 mile time trial. Maybe.

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.

Cervelo P3 Test Ride

1001 Albums (41-60)

I've changed the format of these blog posts, and I'm just pasting my commentary from the 1001 Albums website. I've left the weblinks in - the album title links to Spotify (I haven't tested those since I don't use Spotify), and the artist name links to the Wikipedia page for the album. The Global reviews link is to the reviews logged on the 1001 albums website.

Frankly, the whole exercise seems to me to be a bit lacking in diversity - hopefully we'll see more non-English speaking albums later on. (Click title to read more)

Indoor Training Part 5 - Rouvy in Workout Mode

Since the beginning of 2024 I've been increasingly using the Rouvy app in my indoor bike training (see Indoor Training - Part 3 Rouvy vs Zwift and Fulgaz). Until the other day I'd only been using this to enliven my indoor cycling on otherwise very dull interval sessions, but I thought I ought to give Rouvy's workouts a bit of a try. And I'm rather impressed.

The 2024 Time Trial Season

The start of my time trial season is looming ominously on the horizon. In 2024 I plan to ride more open events. Over the last couple of years I've ridden fewer open events (which are usually at weekends) because of various family issues. Mostly those issues have kept me from being able to race at weekends. Our club events are usually mid-week, and therefore have fit better with my lifestyle over the last couple of years.

VTTA Zwift '10' - Round 5 6/2/24

This was the fifth event in the VTTA's Zwift virtual 10 mile time trial series. Over the first four events, I'd seen a gradual improvement from 24:18 to 23:53. As far as I can tell, the improvement is mostly down to improved consistency in maintaining appropriate power levels, and this event saw my most consistent power so far.

My strategy for this was as follows.

VTTA 10 mile Winter TT league - Event 4 30/1/24

Another Tuesday, another VTTA Zwift time trial.

Aead of this time trial, I decided to splurge some of the 40+ million drops I'd accumulated in Zwift and buy the best frame and wheel combination available. At least as suggested by Zwift Insider. Armed with a (virtually) shiny new (virtual) cadex TT frame with (virtual) DT Swiss wheels, I entered the fourth in the eight event VTTA series.

Comparing power values - Tacx Neo vs Assioma pedals

Recently I'd become interested to see how the power reported by my ageing Tacx Neo smart trainer (first generation) compares with my Assioma pedals (i have the dual set). My initial investigations involved fitting the Assiomas to the bike mounted on the turbo and comparing the reported power by eye. This seemed to have a significant different at least at some power levers, so I felt some further investigations were merited.

Logitech announces termination of mysqueezebox.com - consternation ensues!

I've posted in the past about the Squeezebox network music players, most recently owned by Logitech until discontinued in August 2012. These devices require a network connection to a server - either an instance of Logitech Media Server (LMS), running on the local network, or the Logitech-provides server at mysqueezebox.com (MSB). The two server systems do have functional overlap which does cause confusion in the user base, of which more later. However, on 25th January 2024 the announcement was made via the support forum that the MSB service would be terminated in February 2024.

VTTA 10 mile Winter TT league - Event 3 23/1/24

In this, my third event in the VTTA 10 mile Zwift TT series, I tried to maintain a steady power. I also tried ride this as I normally do road TTs - that is, at a very low cadence. This worked marginally - I seem to have improved by a piffling 4 seconds! At this rate I may have cracked 24 minutes by the end of the 8 events!

Indoor Training Part4 - Intervals.icu

I came across intervals.icu a couple of years ago, via an article written about 2021 Olympic road race winner Anna Keisenhofer. In the article she noted the complex and adaptable graphics that intervals.icu delivers, based on data drawn in from a number of sources.

1001 Albums (1-20)

At the end of December, I came across the 1001 Albums You Must Hear Before You Die website, based upon the book of the same name. After signing up at the site, you receive a daily album suggestion. There's an app for Logitech Media Server which links to a copy in your local music library, or failing that to your streaming service of choice, making it easy to listen to the album.

So far, I've had 22 albums - several of which I own in some format or other, some were new to me, and some have been added to my collection. As far as I understand it, the albums from the list are presented in a random order. Here's what I've had in order of appearance. Here are the first 20 albums.

VTTA 10 mile Winter TT league - Event 2 16/1/24

If I was a little disappointed at the outcome of my first effort at Zwift time trial racing last week, I did at least pace myself a bit better than I did in event #2. This was held on the same course as event #1, the pan-flat Tempus Fugit course. After a short delay occasioned by an unexpected Zwift update on the Apple TV, I set out to spin through a warm-up ride.

I’ve had a fairly heavy training load over the last week, so maybe I was left a bit jaded. However, the principal failing this evening was a that I didn’t keep a consistent power level through the event. Starting too hard was just the start. I lacked any kind of serious motivation, and repeatedly felt like I just wanted to stop. In fact there’s a surprising number of pauses in the record of the ride (see below).

About Flies & Bikes

Flies & Bikes is a website/blog that I started some years ago. Initially I was writing about my interests in Science and my hobbies which include cycling (touring and racing) and tech stuff. At the time I was a University academic, but as my time available to blog waned, the focus shifted towards cycling and tech, then eventually it entered a rather fallow period.

My First Zwift Race

 

I've been using Zwift regularly since April 2020, when I was building back from being an 'early adopter' of Covid-19. In all that time, I've not raced in Zwift, and I've only very occasionally ridden with friends on Zwift.

Until now.

Indoor Training - Part 3 Rouvy vs Zwift and Fulgaz

Part 3 of this series is somewhat delayed by Christmas and associated shenanigans such as the traditional Christmas Cold, which really flattened me for a couple of weeks.
