Distance on the IDT does not relate to distance on a bike. It can be used to compare one IDT session to another (if you also record resistance, etc) but as said before, its pretty academic.

Your front brake gives you 70% of your traction. If you don't use it you are not going to stop very quickly.

Its really about finding what works for you. The pros take minimal spares I think. Try looking for a saddle bag that doesn't break or work its way open (yes I've also lost car keys like that). Or else like you say, reduce what you carry. You also get those park tools bottles that fit in your bottle cage, but are made for tools and spares... You not missing anything, you just have to find what is best for you.

How much have you run before? If you haven't run much, I would strongly recommend a slow introduction to running. Tim Noakes in his book "The Lore of Running", has a beginner programme that starts out with walking for about 2-3 weeks before even running, and then begins the running with 5 minutes at a time. This sounds quite extreme, but research has shown that beginners often suffer injuries. Ironically, in his book he states that generally fit people are more prone to injury as they increase their mileage before their bones/joints/tendons are ready for it. In March, my friends and I (all cyclists)decided to aim for triathlons at the end of the year, and after following this approach, I am the only one of us that is not injured at the moment, all running related. On top of that, this is what Joe Friel has to say about long runs: "When it comes to running, the purpose of the Base period is to increase the duration of your weekly long run to no more than three hours in zones 1 and 2 only. Yes, that’s right—no more than three hours. In fact, you only need a couple of these. Most of the long endurance runs will be in the neighborhood of two-and-a-half hours. Why? As the duration of your running increases your risk also increases but with no greater benefits gained. In other words, you are more likely to get injured running longer than three hours while becoming no more fit than with shorter runs."

Hey Chris, I'm in Weltevreden park and work in Braamfontien. Its about 18km for me, but I have worked out a few routes that reduce traffic, etc. and the climbs aren't too bad. PM me if you are interested. Rob

Yeah, they are older than 2 years. Should I dump them?

Hey guys, My girlfriends Maxxis Monorail UST tyre has fine hairline cracks running lengthways down the tyre. They appear to be caused by perishing- they don't look like they are cuts or anything like that. There is no loss of air or leaking of sealant. I also suspect it has been this way for a while. The tread is still got quite a lot on it, I would say 50% at least, and it would be nice to keep them running for a while longer. So are these cracks confined to the outer layer? ( would assume so because there is no leaking yet) Is this going to suddenly and catastrophically explode? Or is it safe to keep riding? I know Maxxis have a rep for being robust, but I don't know if this is serious or not. Thanks for the help.

Plan well Possibly leave clothes at work on your non-commute days to reduce what you have to carry. Lots of lights/reflectors A fair bit of common sense and anticipation (expect all car will do stupid things). Ride leisurely to work to reduce sweating, and ride hard on the way home. Enjoy the great feeling of not sitting in traffic, saving petrol, saving money, saving the environment, training, saving time, etc.

Wow, you must be really strong!

There is now a mountain king II, and a X king. I think the X king is sort of in between mountain king and race king. I.e. it rolls a little better but still has a lot of grip. And the mountain king II has more grip but a higher rolling resistance (aimed more at all mountain?). I haven't tried either of them yet, as I am still on the original mountain king (which by the way is great).

I think if you are going to use ratio's you should use the time ratios of the event rather than the distance ratios. For e.g., during the race you may spend 1h swimming and 3 hours cycling. Then the ratio is 1:3. That would be more reflective than the km of the event.

I already had one stans strip (your second link) so I used it on the one wheel and it worked perfectly (as they do). I had bought a pair of valves simmilar to the following link for my other set of wheels which are actual UST wheels, and I thought I would give it a shot on the second wheel and it also worked easily. No tape or anything. http://www.cwcycles.co.za/product/stans-no-tubes-universal-valve-35mm I used old used UST tyres because they are my training wheels, and some stans sealant inside. http://www.cwcycles.co.za/product/stans-sealant-950ml I would recommend UST tyres for the puncture resistance, although some of the racing guys use normal tyres because they are lighter, but I think they would puncture easier. Your other option is to do a "ghetto conversion" using a bxm tube. If you do a search you will find a thread that explains it nicely.

Why make it so complicated? Sounds like you are fixing up an old bike... Why not put on a standard size cassette, which is usually 11-32. Also you say you don't need a crank, so why get one? If you do get one, why a road one??? you seem to be making this very complicated. Why go 2x9 unless there's a good reason. 3x9 has been around for a long time on MTB's for a reason. KISS

With those MT15's you dont need a special tubeless kit to go tubeless. I have just set up a new set as training wheels. I would strongly consider it.

In this day and age, what puts these frames above others? Is it just a brand name or something else?

I always wonder why there are hundreds of XXXL left at the end. Surely if they don't know the demographic, they will err on the side of too many mediums. But this is never the case. I use the shirts for gym and the trainer.

Some say he uses cooking oil in hydraulic brakes... All I know is, he's called JB

Wow, those look like 2 extremes... I think it will change your bike handling quite a bit. What's the angle on the 120mm? 15 degrees? I know that you have already installed it, but if it were me I would reduce it to a 100mm 5 degree rise first, then an 80mm, etc.

You can't compare this to Whistler unless you propose building ski lifts and proper NS trails. The infrastructure and trails there are far superior.

What is the distance for that one? and do you have a link?

Very easy. I do mine and save about R350 a pop. When you should (according to manufacturers spec) service it every 50 hours, that adds up quite quickly. Its a Fox fork. I'm sure spring fork is even easier and could be done in your sleep

Well it took you 3 months to reply, so you cant be that fast!

Ceramic bearings are for extremely high rpm and temperature applications. Like above 20 000 rmp. Biggest marketing gimmic ever

I would be interested to see other peoples answers to this. My habit is generally 1 item (bar or banana) per hour, but I often eat less because I cant stomach it. So for example, if its a 4 hour ride I will have a jungle bar after 1 hour and after 2 hours, and then have a gu or two to get me home. I generally drink 2x 750ml bottles, and a few cups of coke/water depending on how I feel.
