That's crazy!!!!

Standard training gear at every keirinjo in Japan.

The same principle behind the parachutes:

I'm scared, though. I've already ruptured one Achilles tendon

gycho77

@babyPukeWow that's really interesting. @carleton I hope your Achillea tender is perfectly cured
And I found this on Instagram.
These track frames look like Bradley Wiggins' hour record bike.

The tire at my home track when I was in Japan was so old that it was actually only one sidewall– apparently it had been used for so long that the rest of it had been worn away. That's pretty damn old.

gycho77

How often did you train with the tire, when you were in Japan?

Baby Puke

Honestly I only used it a couple of times. Most of the time I just saw people dragging it around on the apron in a big gear rather slowly, so benefits looked dubious at best to me at the time. But using it as an anchor for starts as @taras0000 suggests seems like the best use for it.

I agree on his hour record bike but today at the WC it appeared he was riding one of the British teams superbikes

I think it helps train the muscles that don't get as much work because the big muscles take over.

Do some single-leg drills with some resistance at like 70 rpm on a trainer and you'll feel the muscles that I'm talking about. The muscles that kick the leg over the top of the pedal stroke are what I'm talking about. There is a serious dead spot there. If you want your 1% incremental gains, look there.

The single leg drill at high load are great. I used to do those near the beginning of my warm-up for trainer sessions (non sprint based). The neural activation helps and you can feel a difference when you back off the load and pedal under race cadence at racing resistance.

Going back to the tire. I found the best way to utilize it, or where it was most effective was for standing start training. The tire would slow you down just enough in your pedal stroke's dead spot that it made each pedal stroke that much more important when it came to accumulating speed. I used to do start on a slight incline, but found the tire more effective. The incline is similar to doing it overgeared. With the tire, the best way was to do it UNDERGEARED. If you race with a 50x14 (96"), then 50x15(90"). The gear was still high enough that you worked against a decent amount of resistance, but the extra leverage allowed you to really accelerate through the pedal stroke.

It works like this. During the start the tire needs to break friction to get going; friction decreases, you move a little; dead spot occurs, tire grabs, friction increases, holds you back, you have to push really hard to overcome; lower gear really allows you to plow ahead quickly, friction decreases, muscles generate acceleration quickly, you move some more, hit dead spot; tire grabs...

So instead of a linear feeling of progression, (2 steps forward, 2 steps forward, 2 steps forward,...), it's stepped (3 steps forward, 1 step back, 3 steps forward, 1 step back,...). You're doing the same amount of work, it's just occurring differently and training force production. I found I was able to "stomp" harder/faster on the pedals after training like this. In the weight room, the same thing can be done with squats from the pins. You would decrease your normal weight by 25%, and have the bar set on the safety stops at 80% squat depth. Wiggle under the bar, get set with just a millimeter of space between you and bar, and explode upward. This is a good one for that first stoke right out of the start gate.

They've started checking for motors in track bikes already

New Planet X Frameset

I obviously missed the memo from Planet X that they have changed their business model from reasonably priced frames to full price! Only 99 pence cheaper than a proven Dolan DF4... No photo doesn't help sell it either.

brawlo

QA costs money, so maybe they're stepping up their game with something more premium?

Or perhaps some stickers on an Axman frame cost a bit?? Interested to see the photos when they come out and the internet trawl to see if it's just another Chinese open mold product

Dalai

Well we have seen the huge premium added to the Axeman frame with a Look paint scheme... Didn't think a Planet X sticker would do quite the same!

carleton

Yeah, I want to know why they are charging so much.

Koogar

Rad - a carbon track frame available in four sizes! Of course there's no need to include a geometry / size table, since "[t]he Koichi San doesn't care what your preferred track event is...."

Thanks for posting this website -- I see Planet now appear to make Holdsworth frames - I bought the professional road frame 30 years ago and has been siting in my basement since then. Mine has a higher grade Reynolds tubing than the one advertised. I paid $250.00 and todays price is $1424.99. Guess I ought to sell it on eBay.

I note also that Planet also sells the Holdsworth Zephyr road/path frameset (mostly used for road TTs when I lived in the UK.) Holdsworth Zephyr Frameset | Planet X

gycho77

That's a good news!!!
Now you should sell your frame on eBay for 800 or 900

Looks like the standard open mould stuff with a few tweaks.

Banchad

Planet X have added pictures of that new frame. I may have been hasty saying it was standard open mould stuff. Thats a funky looking fork.

looks like the fork affinity uses on the kissena nowadays.
