Wool jerseys, toe clips, and an egg shell helmet brings back memories. I do remember doing hand slings back then. Pushing was reserved for newbies and for experienced riders on the brink of exhaustion. A 100 lap madison twould take a lot out of a rider.

BTW, we called them egg shell helmets (the one on the right) because if you fell they would crack open like an egg shell. Still, we believed them to be safer than the leather hair nets. Given the perception of additional safety, I even rode a Brancale on he rode which wasn't a popular thing to do back then.

I heard that Cervelo is reproducing Cervelo T1
Do you think this is true?

This information is based on my friend(Korea).
He heard this information from a bike shop.

T1 no, well maybe they will call it that, but a new 'mass start' entry level bike, and a higher end carbon frameset.

I was expecting it to be released already, but maybe not be until closer to Rio when most companies see their track sales 'bump'. Also when the brits are riding them

gycho77

Thanks
I should tell my friend about this

In regards to straps with clipless. Is there any particular point where its recommended to use them? Just curious to be honest as I'm nowhere near able to pull my cleats out of the pedal. Is it more of a 'just in case' than an actual necessity for us amateurs?

gycho77

Good morning
I know a "Single gear" cafe(based on Korea).
This cafe is based on fixed gear bikes, and the users are all adults( above 19years old)
There are many track parts on sale in cheap price.
ex) ½Ì±Û±â¾î : ³×À̹ö Ä«Æä
Sometimes there are amazing deals.
Do you think I have to post them on this forum for trackies? or no?

Also they sometimes sell Mavic comete, mavic io, and LIGHTWEIGHT track wheel!!!!
Right now they are selling comete and lightweight etc.

carleton

No. You shouldn't.

We can link to products that we see for sale to answer a user's question, like "Where can I find some Scattos?" But, simply listing their classifieds here is not allowed.

There are 2 benefits to using them. The first is obvious. If you think that you will pull out or have done so in the past, they are options. But, also, they help with the upstroke when pedaling.

Our feet move vertically several millimeters in the shoe each pedal stroke. This really depends on your shoes. Some shoe uppers are worse than others, but all do it. The straps eliminate that "slop" for a more solid connection.

Double straps are not needed for most. A single on each side will do.

The downsides are obvious, too. Cost. Quality straps cost around $100. It's not worth it to use cheap ones. Also, they can be difficult to mount even for regular users. You are always at the boards/rails fiddling with your pedals before a race. To some, it's not worth it.

Personally, I strongly believe that ALL time trial specialists should use them (even 3K, 4K, and longer). They are "free" watts.

Think about it this way: If your cranks or pedals shifted a few mm every pedal stroke, you'd have them replaced, right? Our feet move vertically inside of our shoes every pedal stroke. Some shoes are better than others. I've found that all except the high-end shoes stretch on the upstroke. Sidi Genius 5s were the worst for me. They were like pedaling in house slippers. They were really comfortable for casual riding. But, not stiff enough for track efforts.

I wear straps for the 2 reasons carl mentioned and pulling out is actually secondary to me (my cleats have a bit of float so it very unlikely to twist out by accident). When you start flailing your legs around at high RPM and max power, its much more confident/stable having that strap tight.

Does it make me faster? Probably not. Might make me more consistent.

carleton

They do.

Anecdotal story:

An older masters guy at DLV (big university professor and scientist by profession) used a power meter because he's a science nerd (like me) and tried straps for the first time. He remarked that he got +150W immediately on his standing starts. I was there when he first tried them. He's used them ever since.

I'd guess that wattage gains for steady state efforts would be higher, too. Even an extra 5-10W in a 3K or 4K is significant.

I mean, I could be wrong about this. None of the big national teams use them with the enduros (that I've noticed). I'd expect the Brits to have at least tested them in training with their pursuiters and bunch-racers. But, my gut says otherwise.

Thank you for your clarification

Why do professional track cyclists use Chromoly steel handlebars(Nitto B123 or 125) over aluminum handlebars(Nitto B123 aa or 125 aa)
Aluminum handlebars are 2 times lighter than steel.
Is it because of stiffness or price?

VanceMac

Weight is almost the LAST thing I'm worried about with my track equipment.

gycho77

So track cyclist use steel handlebars for stiffness?
I thought aluminum is stiffer than steel

Thank you for your help

VanceMac

I happen to use the aluminum version of the 125s. Can't really speak for anyone else, but steel is cheaper and will likely take longer to fatigue. Stiffness, you'd have to test, since it's not always apples to apples.

As for "2 times lighter than steel"... not really true for these: 350g vs 316g.

gycho77

Based on velodromeshop
Nitto B125 Handlebar from Velodrome Shop
Nitto B125 AA Handlebar from Velodrome Shop
2 times lighter than steel

VanceMac

Ben's lists the weights I quoted, but appears they are wrong. 12 ounces still wouldn't matter to me on the track. Though again, I have the aluminum. (Also, at that weight, it wouldn't surprise me at all if the steel were stiffer.)

gycho77

Oh I did not know that
Thank you for your help

Baby Puke

In my experience, and I have used both aluminum and steel versions of both 123's and 125's, the steel is marginally stiffer, but more importantly (for me) significantly cheaper!

gycho77

Thank you for your information.

The steel are so stiff that they are uncomfortable on a bumpy track.

Unless you are stronger than average, Nitto B125AA are fine. Just get some narrow ones. Also, the B125AA are just about as light as the Scattos.

But, weight really shouldn't matter.

If you have the extra funds, go for B125AA. If you are on a budget, get B123 (narrow for both). Scattos aren't worth the $$ for new racers unless you've bought everything else (skinsuits, track annual pass, aero helmet, aero front wheel, etc...)

While we're on the topic of handlebars has anyone got any experience with the Velodrome Shop own brand Chromo bars? Velodrome Shop Chrome Track Bars

I'm looking for a set of handlebars to replace the ones on my commuter fixed as I can feel them seriously warping and creaking and I'm getting a bit scared they're going to snap on me.

This doesn't really answer your question; not sure if you've had a good experience with VDS but you might contribute to https://www.bikeforums.net/track-cycl...eshop-net.html
