Alan Partridge is on Sky Atlantic at 10pm.
It's a new hard hitting one off documentary.
Like something Donal MacIntyre or Paul Williams would do, but maybe not as funny.

I miss his sports coverage, nice to see him back on the telly after that unfortunate shooting incident.

The Sky channels from 901 on might help......

I've been thinking about upgrading my groupset, it's certainly something I'll do before the summer is out, currently running with sora

I do have an old but barely used ultegra 9spd cassette in the shed and was going to pop this on, it's a 12-25 but also 100g lighter, this prompted me to have a bit of a dig around online about cassette weight. From my reading the belief is saving 100g on a cassette is the same as saving 100g on say a seatpost. Now if I relate this to say race cars there is something called sprung weight and unsprung weight, basically anything outside the springs is unsprung and a 1kg saving here is worth 8kg inside the car.

This I believe would be same with the cranks, cassette, rear wheel and chainrings, essentially the bits being turned by the rider.

Am I making sense here or am I just talking sh1te?

Now none of this means anything to me cos I'm nowhere near fast enough but I would like to read more on this so if anybody could point me somewhere

Transcript of the "phone call" refused under data protection? Ridiculous - it's HIS data!

Highly unlikely that individual Halfords shops record calls. Anyway what did he expect bringing his bike there? Probably would have been just fit for the bin after their 'repair' anyway

Can't turn you anywhere but my understanding is the opposite, sort of, anything that turns on a bike adds more weight. Hence why weight saving in the wheels is far more beneficial than anywhere else on the bike.

The further from the center of the wheel the weight is, the worse that effect is. Therefore heavy rims and tyres cost more than heavy cassettes. The differnce between 100g on the seat post and the cassette may be marginal as the cassette is close to the center and the seat post is abover the centre of gravity so may have other issues depending on your riding style.

TLDR, lighter wheels are the best starting point for weight saving that will be noticeable while riding AFAIK

I used a CO2 cannister today, the audaxer in me feels ashamed. On the other hand, the lazy sh1t who is late for everything has found a new path.

On the back of the Giro (and in case anybody gives a tuppence), the Dutch Men's Road cycling team was named for the Olympics yesterday:

Kruijswijk
Dumoulin (RR and TT)
Poels (RR and TT)
Mollema

Marianne Vos has been named amongst the ladies to defend her Olympic title.

Any ideas on when the Irish two will be known?

The second one:)

Rotational mass and it's effect is a completely different topic to sprung/unsprung mass.

In a race car lowering unsprung mass is beneficial to how a car will handle to steering inputs and stability under hard braking acceleration.

Really cheap way to cut 500g-750g from your bike, bring one water bottle

Possibly related: according to Veloviewer my old steel bike (Croix de fer + 105, 11kg) was 1km/h faster than the new alu+carbon one (Kinesis Pro 6 + 105, same wheels and tyres, 9,5kg) over 3500km distance sample (26.9 km/h vs 25.9 km/h average)

The new one is snappier and definitely better in CX races, but not necessarily in normal rides - and I often ride hilly ones, where the mass should theoretically make a difference...

On the basis this might stop people buying a new bike, I request that this post be deleted.

Did you eat all the cake since abandoning the Croix de fer?

Alek

There may be something in this

In fairness I don't have time to do longer rides since changing bikes, while I've done +/- 8 audaxes on CdF and many around 100km... but how does it contribute to avg speed?

CO2 is heavier than air. Therefore you have added weight to the outside of your wheel.

Thus inexorably is your atonement exacted.

A bit of heavy braking and I'm sure it will all be back to normal....

Same here, I was definitely faster on my Charge Juicer than I am on my fancy new bike. Found it easier, climbed better, carried more weight uphill.

There may be a pattern here as well since I haven't done any audaxes since switching over

I think we are just getting younger, Cram.

I cycled out to and around Howth for the first time yesterday but can't help but think I missed a trick... I turned left and went along Harbour Road first and then up towards the summit but it seems as if I was the only cyclist to go this way as there must have been about 40 cyclists who passed me going the other direction!

Is that direction the one that all the Strava segments are on or something?

magicbastarder

that's the only way i've ever cycled over howth head (only about ten attempts, mind). i'm not mad keen on the idea of descending through the village.

traprunner

I've always gone up from the Sutton side. I'm not overly fond of hills and the village side looks too steep for me. Yes I'm a pussy! Most times I come down the way I go up but occasionally I descend through the village. I wouldn't do it on a sunny day though as there are too many cars around.

Just saw Peter Kennaugh in full British Champs Sky kit with his Sky Pinarello standing with a fellow Sky team mate on Ballymun Road. Either that or the saddest full kit **** I've ever seen.

well with Kennaugh out of action and on the isle of man you have your answer.

I feel bad enough in some team kit nevermind then riding the bike to go with it

Once he wasn't dissing womens cycling like his idol, he gets a pass!

So I was on a Dublin bike for the first time in years. I think I see why so many people act like plonkers on them. They feel like a tank and can go through any pot hole or off any kerb without a bother. The weaving I've witnessed has to be caused by the steering. Slightly moving the handle bars makes the bike mosey to the side. The sitting position made me feel indestructible compared to my hybrid or road bike. Also, the brakes were crap. So basically I think it could be down to design incorporated with being an idiot.

Yeah the climb out of the village was quite a shock to the system after stopping in for some fish and chips but the clear descent was very enjoyable!
