Feel free to beat my max ever heart rate.

170bpm

I cannot get my heart any higher than that. Even when I did my VO2Max test, I only hit 169bpm.

From what I gather, the best way to increase your lactate threshold is to do interval training.

The measure of millimetres for rainfall is by the square metre. So if they say that an area got 10mm of rain, then every square metre had enough water to cover it by 10mm. So a bucket is an accurate measure of rain, but you need to workout what it's capture surface area is and increase the depth acc...

jimmy

It isn't just the water that is the problem, if your BB is greased properly, then the grease should keep the water out. But, as we all know after riding in the rain, there is a lot of foreign material on the road, and the water will carry that, some of that will get left behind in your BB when the w...

jimmy

I haven't yet done a BB Service, the main reason being that I haven't had the tools to do it.

I have a BB tool on the way, so I am going to start doing it more often.

James

Bit off topic, but if anyone is after any solid state memory for cameras, digital video cameras etc, let me know and I will give you a price.

My company (Express Online) sells SanDisk products, and I am able to buy directly from them. Compared to RRP, I can often get it about 40% cheaper.

There is no organised ride for Renegade this Saturday (9/2), but we have already sorted out to do West Head. So, if anyone is interested in joining you are welcome, just let me know. The express to Lane Cove will be leaving at the 7-11 on Stanmore Rd at about 5:45am. Total distance is a about 105km ...

jimmy

Typically, I don't mind riding in rain in summer, as you said Geoff, you can only get so wet, and you don't get cold this time of year. But as I commute by bike (I have no car and public transport isn't viable), I prefer to stay dry on my weekend rides. I have done enough riding in the rain as it is...

jimmy

Mike, PM me a physical address and I will post you the DVD.

I asked Eugen to send the video to my gmail account, I will upload it somewhere once I have it.

Looking at the radar at 7am, there is a decent amount of rain in the Sutherland area, which is about where the group would be.

OK, I feel justified in bailing this time.

James

jimmy

5:30am - Raining pretty well at my place, looking at the radar, it is heading South West, so the start of the ride would probably be pretty wet.

Also, seems that there are some showers in the park (or at least in that area).

Sorry guys, I am going to bail again.

James

jimmy

Weather permitting, we are off for another RNP Ride on Sunday.

Leaving at 6am (sharp, especially if I am there), doing it widdershins.

I have something to train for now, so I am looking to dish out some punishment.

James

jimmy

You also have to watch on days like this when it hasn't rained for a while. The cars dump oil on the road, which then gets lifted by the slight rain, which makes it even worse.

I know that I ride a lot more carefully in the wet compared to the dry.

James

jimmy

The other issue with a barometric altimetre, is that if the air pressure changes during the ride, it will change accordingly.

James

jimmy

Power != Force They are different measures. Take it to a Lightbulb, a lightbulb draws say 100W, now over an hour, it draws 0.1KwH (Kilowatt Hours), you don't look at it and say, that it draws 100W in this minute, and then 100W in the next minute, therefore it is drawing 200W over 2 minutes. It draws...

jimmy

I was thinking, if my legs produce (don't know how to best describe it) 2W per pedal stroke and I peak at 100 cadence, before loosing the 2W output, then I'm producing a max of 200W. If I can move that peak up another 5 cadence, then I'm producing a max of 210W out of the same 2W legs. You are talk...

jimmy

I have heard that your average Pro Road Sprinter hits about 1500W, so Boonan at 1600W isn't that surprising. As far as the testing goes, I have done something similar (the maximum sustained, not max power). This was done on a special exercise bike. It was able to have a set amount of resistance, tha...

While the Mona Vale Rd Intersection is only 165m, it does climb soon after at Pymble Hill. As Geoff said, there are a multitude of climbs on the North. Galston Gorge Berowra Waters Bobbin Head Akuna Bay Brooklyn Bridge McCarrs Creek Rd Further, many of these are quite close to each other, so you can...

jimmy

Having done a few Cycling Holidays, I have learnt (the hard way) that if you have more riding coming up, it is better to keep riding rather than take just a single day. Look at the Tour de France (and other GT's), even on the rest days, the riders still go out for a ride, they just do lower intensit...

The other option worth trying is Google Video as a hoster.

As Google bought YouTube last year sometime, I suspect that there is no difference between using YouTube or Google Video.

Here is a Direct Download Link for Virtual Dub.

See if that works for you.

Weiyun is right though, I have had fun and games trying to do video editing, it can be a frustrating and unrewarding experience at times.

The problem with the sun rising later at the moment. Although we aren't often riding straight into it, still a careful reminder to be attentative.

For Windows Video Editing, best bet is VirtualDub.

Ride Report There were 4 at the start at Mick Mazza's this morning. Simon (who got his road bike out of long term storage :-)), Eugen, Paul and I. Surprisingly, a strong Southerly had picked up at about 5:30am or so. Subsequently, the ride started off tough. We picked up Fred, George and Eddie at Lo...

jimmy

I went through the RNP clockwise today, and while I was at it, I did some timings. Although I was doing some of it the wrong way, I suspect that the times would still be pretty close. From the Entrance to the RNP to the bottom of Waterfall was about 45 minutes, so I would expect a return leg to be a...

jimmy

Thats awesome getting so many people on that ride. Two questions though. How many of them are club members? At the end of the day we need to ensure that the long term viability of the club is guaranteed, which means increasing the membership. The other question, is how many are likely to make the tr...

jimmy

OK, so shall we say 6am at Mick Mazza's, which means that we will be passing Loftus Oval at about 7am to pick up Fred. Planned Route is Waterfall, Helensburg, Stanwell Tops and then back through the RNP, we can exit at either Waterfall or Audley. My vote is for an Audley exit. The possibility exists...

jimmy

I would prefer to stick to an early departure. Monday is the last day of a long weekend, on top of the fact that School starts again next week. I think that the roads will be quite busy. By having an earlier start means that we would finish earlier, so hopefully we can avoid more of the traffic. James

jimmy

I am going to put a PBK Order through tonight, if you want anything let me know and I will add it to my order.

I am going to place it when I get home tonight, so I will place it at about 8pm.

James

jimmy

What time approx. will you be going through Sutherland? and will you be doing the big dipper or not? Depends on who else is coming. If there are others, then I would expect a 6am depart from Mick Mazza's, so going past Sutherland at about 7am. If there are no other takers, then I would be leaving h...

jimmy

Yep

I posted about this last week and heard nothing. I was going to do Waterfall, Helensburg, Stanwell Tops, then back through the RNP to Audley.

I think that you will find that most frames have Conditional Warranty, whether they have 1 year, 2 year or lifetime. The Conditions on Warranty are usually pretty standard, they only cover the original owner, so most second hand frames will have no manufactures warranty, and they only cover fair wea...

That is actually a pretty good idea, obviously if you have the time, it is probably a pretty good way of getting a cheap messenger bag.

I think that motorists fall into one of four main categories in relation to their attitude towards cyclists. 1) Considerate - They are prepared to give you as much time as you need to take, will give you plenty of space when passing you etc. 2) Ignorant - They don't care either way, but they won't a...

Yeah, I piked. I got up, looked at the sky, looked at the ground, and decided to go back to bed. As it turned out it was a bad call and I could have got at least one ride in over the weekend.

In relation to the original topic, and from Eugen's other post regarding the road rage he experience, I thought that I would pass something along which I have found. First, up, I am aware that dead right is still dead, obviously you have to learn how far you can push this before trying it. When the ...

jimmy

which means...

RNP!

This time, we already know which way we are going to. In at Audley and out at Waterfall.

At this stage it is weather depending, but I am hoping to be at Mick Mazza's at 6am on Sunday.

See you all there...

I was under the impression that it is a UCI regulation that requires a freewheel.

I could be wrong on that, but as I understood it Lindsay always rides single speed, not fixie at Heffron.

Also, forget about compact and semi-compact frames. These exist only to save bike companies money, and don't handle as well as traditional geometry. Funny, my Cervelo, which is compact frame (or maybe only semi-compact) handles like a dream. The only issue I have is that it is very short, so I get ...

jimmy

While Cell may be good on price, I would recommend them in the same sentence where I would recommend someone try Leprosy.

I would prefer they go to a shop who will actually listen to what they want and sell them something suitable, which is pretty much most bike shops (except Cell).

I don't know about the rest of you, but every now and again, someone asks me about advice for a bike.

Judging by what you have put up there, you are looking at spending $3,000 - $4,000 at the most. From what I have seen, there are a lot of bikes in that price range, all of them good. At that point it basically comes down to trying to find the best deal on a bike that you like. I had a look at KOM Cy...

jimmy

If you do it clockwise you're generally still (relatively) fresh going in at Audley, which is the commitment point. Anti-clockwise if it's been a solid pace down to waterfall, you're that little bit less fresh to do the park and the commitment point is a little bit later on. So it can be tempting t...

jimmy

This morning on the way in, I was thinking about our RNP rides. There seems to be a preference in the club to do them in a clockwise direction (in at Audley, out at Waterfall), I have no objection to doing the Park this way, but I think that we are missing out on doing it the other way. So, what I w...

The more expensive frames i'd of course expect a lot more from. You'd be surprised The Pinarello Dogma that I had, didn't have a replaceable dropout.

Yes, it showered on us twice, once just as we were started on the West Head Rd, and the other time when we were climbing up McCarrs Creek Rd.

Both showers were pretty short though.

jimmy

Mike

Route will be through Annandale, Balmain, Drummoyne, Lane Cove, then Pacific Highway to Mona Vale Rd, then to Terry Hills, then out to West Head.

James

jimmy

If we left the 7-11 at about 6am, then as per New Years Day Ride, I would imagine that we would be back by 11am.

Unlike the 3 gorges ride, there is only one real stopping point (West Head), but that is often a longer stop.

James

jimmy

Mike

Do you have any time limit? There doesn't seem to be a Renegade Ride on, and I am thinking of doing West Head, expect about 108km from my place (Stanmore Rd).

Sunday is the first Sunday of the Month, so I would prefer to miss the RNP on Saturday.

OK, from what I understand there was a ride planned on Boxing Day for Galston/Berowra/Bobbin (GBB), this is why I proposed West Head. So, as Eugen pointed out, GBB is a shadier route, and as long as the ferry is running, it is an enjoyable ride. So... Lets do it backwards. Bobbin Head, Berowra Water...

jimmy

It would depend on how much we stop. I would imagine that a good get away time would be about 6am at the latest, (preferably earlier). West head is about a 110km trip, so I would expect that we could return by 10am if you are prepared to push. I wouldn't imagine that we would be much later than 11am...

I typically do nothing special on NYE, so I am up for a ride on Tuesday (1/1/08) next week. I was thinking of something north.

he can turn his rear wheel around to get a free wheel out of it. It is still a single speed, but he can freewheel.
