Lactic acid doesn't build up in the stomach, it is part of the fuel system that helps muscles drive when there isn't enough oxygen being delivered through the bloodstream. More likely that you pushed your body into stress, and that has a variety of outcomes from nausea, to vomiting, hyperventilation, muscle spasms, all sorts of wierd and wonderful things. The best way to avoid it is to experience it on a regular basis! :eek:

I'm not kidding, just keep building your fitness up and start getting hard intervals into your training regime. Your body will adapt over time and you will be able to cope with more stress during a race before the symptoms come on (if at all).

Phil won. So what's new?

Jammed my thumb in the car door on Saturdee and didn't race. Had a nice sooky Sunday taking kids to soccer, baseball, swimming, shopping, the park. Arghhhhh

thanks thylo and Jock. shows that my understanding of physiology was not up to scratch, i was under the impression that lactic acid ended up in the stomach and when it got built up thats what makes you want to blow chunks.

i figured that once it has happenda couple of times it will get better. my pre race eating plan was in disaray with the staggered start. also suffered from having dirt crit fitness , where i was fine for the 1st 20 or so minutes (dirt crit length) then POP, the pressure valve went...... will work on it some more with the race up at ourimbah this weekend.

comforting thing was that my 1st lap was a 28 minute lap, where the middle c graders were doing that. if i hadnt blown up i may have matched their times.

Hang on a minute. Expat, Australia isn't an expensive place to live. The cost of living (the basics) is very affordable on a global (western) scale. Where the US has us beat is the cost of luxury goods and the credit system (bank loans, credit cards etc). If luxury goods and cheap credit is your definition of 'lifestyle', then yeah, you're right.

It's also unfair to compare Sydney to the rest of Australia. Even we cry when we have to go to Sydney. Sydney is the Paris Hilton of cities - good to look at for a laugh, but really quite a dud lay, and definitely not worth the money. :lol:

Did you spend any time at all down here in Melbourne? Melbourne is much less precocious than Sydney, is much more affordable, and doesn't try so hard. :)

On the whole 'Internet Business' thing, I have to profess we're totally backward in that respect, so anyone expecting to make some sort of living via net based sales is going to struggle in the next three to five years. We don't have the history of 'catalog' buying like they do in the US and are skeptical of credit cards and companies that haven't been around for 30 years and don't have a shop front. This is slowly changing though as people's cheapness trumps their skepticism. "It won't happen overnight, but it will happen"

What would make me move overseas is not a lifestyle problem, but more of getting sick of the parocialism and apathy (and worse) that we're becoming renowned for.

not Sunday, bronze training. Got my first ever surf rescue in yesterday. I'm now officially as cool as the Hoff :)

"Greg Henderson (Health Net) is getting neutral service at the moment. He has them re-taping his handelbars whilst riding along at 51km/h (32m/h). He's one of the teams best sprinters and will want some grip on his bars for the sprint later."

and Chaddy is off the front again hammering, doing his bit for Aussie toughness :)

All together with 10km to go. Bring on the sprinters

I asked this over in the mtb forum, but the nobs over there are to busy talking about critters they've seen on their rides and other useless crap to answer.

Anwyay, I've filled my mtb tubes with stans. Noticed that they have a heap of thorns in them. Is it okay to pull the thorns out and hope the stans will seal the holes, or should I leave them in? I'd think the thorns would eventually rip the tubes up, but you fellas might know better?

Dude, wouldn't it have been better to chuck the swiss cheese tubes, and buy and fill new ones?

Gah, I'll tell the story properly. My sister wants me to go out with her every day for a month to the local mtb track to learn how to ride a mtb better and for fitness. So we've been going out for a week, she got one puncture and I got one. Got some stans, and as an experiment, fixed the punctures then put stans in those tubes, and left the other tubes stanless. Anyway our last ride on saturday, she got another flat in her non stanned tube. Then the next morning I noticed my non-stanned tube was down as well. After going over the tire, I notice that I actually have 3 thorns in it. So I fix the punctures and put some stans in the tubes. Then I think to have a look at the stanned tubes that didn't go down. Turns out they have a heap of thorns in them as well. So I pull the thorns out of mine, and air starts pissing out, and if I let the wheel spin so the place where the hole is is at the bottom, then the stans starts pissing out. So I spin the wheels and the holes eventually seal.

So back to my original question. Should I have left the thorns in? Another question, will that tube be alright to hold it's air with the stans, or should I patch the holes?

you put stans in your tubes? wierd! how do you get it in there in the 1st place?? using a syringe via the valve? you can do a poor mans tubeless using stans and a set of tyres with hard sidewalls like Larsens. but ivenever heard of somone putitng stans IN their tubes.... maybee im out of the loop? for the cost of stans, wouldnt you be better to just go and have some spare tubes?

have considered running it on my tubless crossmaxs, but havent had a need to yet...

Go Hendy. He's been travelling a lot lately. Tour of Southland (NZ) late last year, back to the US for HealthNet training camp, back to NZ for the Tour of Wellington, back to the US for the Tour of California, and now more HealthNet commitments then Melbourne. He should be over the jetlag by July :(

I just managed to breathe, pedal and stay with the bunch on Saturday with our team animal pulling us along at 49kmh (Russell Nant, 1974 Comm Games bronze medal in team pursuit,) never mind getting the bars retaped at the same time. Those guys are amazing.

i'd replace the tubes saccy, you could leave the thorns in and hope to keep the seal around them but any movement in the tyre/tube, it'll create air pockets the Stans sealant needs to keep filling, eventually you'll run out of sealant.

And yeah, how in the hell did you get enough in the tube is the first place? Musta been some operation.

So much for Stans being a tubeless system! :P

I'd pull 'em out one at a time and see what happens. Just for a giggle.

Then I'd ditch the tube altogether and go somewhere with compressed air and make 'em tubeless. (Which I've been meaning to do myself for about 6 months now) :rolleyes:

Can someone please explain to me what "Stans" is? Is this an MTB thing?

On the bottle it says you can use it in tubes, and they say they do it over in the mtb forum. To get it in, I just spent ages with the bottle and the cone shapped applicator thing that comes with it squeezing and shaking it in. Didn't actually know if i'd got any in until it started pissing out after I pulled the tube out.

A syringe is actually a bloody good idea. Think I might go down town tonight and mug a junkie for some of his syringes.

Thylo, over in the mtb forum, them seem to think tubeless is a rort and that things are lighter and simpler if you just leave the tubes in. Or am I getting their gist wrong?

Wil, stans is just this liquid sealant you put in usually tubless tires to stop them going down when you get a puncture.

Btw, a big bottle of stans cost about the same as 2 of those fancy Specialized tubes with gunk already in them (~$45), so I thought I'd go the cheap route. Is a pain getting the stuff in though.

I run tubeless and love it, id never go back to tubes offroad. less punctures esp with kevlar sided tyres which seem really prone on tubed tyres. can be more flexible with air pressure and its jsut a lot less hassle.

as for weight? its a little heavier, but my crossmaxes are miles lighter than my old mavics. a lot depends on tyre choice.

$45 for tubes? !! farken hell. buying the LBS a second ferrari? how often are you flatting? what tyres ar eyou using as well?

i know that GEAX make a puncture repair in a can. ive never usedit but people i know have used them in races and say they are a good option. you put it ont he tube, and fill it up, works like a C02 cannister but has slime in it to seal the tyre as well. i think you get around 40 psi out of one applicaiton? if your using GEAX tyres, i can see why they invented this as they from experience pinch flat more than anything ive ever seen.

also, an old trick is to coat your tubes in talcom powder. in theory thi sis supposed to make it more slippery and less prone to pinch flats and thorns. i dont know if its an old wives tale, but maybee worth a go?

$20 for each tube. Normal tubes are about $12 so considering it's only robbery, not extortion.

Using kevlar beaded larsens at the minute. Their sidewalls don't seem to rigid to me. And I seem to be flatting every ride at the minute, hence the stans path.

Yeah, do the talc trick sometimes. I've never had problems with pinch flats though. The high volume Larsens seem pretty good with preventing that.

Good to see you guys going on about MTB stuff again. :D

I use GEAX (mezcal) tyres and haven't had any problems with pitch flats. Had one where the sidewall split (rock scored the side) though. But since replacing I've had no problems. Mezcals rock, fast, pretty light (540g), predictable.

Pinch flats... Try running some air in your tyres, that usually helps.
:p

Larsons... Light yes (~500g for eXception), I also split the side wall on one. Bit of duct tape on the inside is holding it for the moment. I seemed to have a quite few flats with the larsons from thorns and other pointly things.

You mean there is another kind of cycling? :rolleyes:

Before this week, I'd never flatted with the Larsens. Guess I've been lucky. I really like them as a tire though. Good predictable grip and not really prone to flatting, at least compared to the Hutchinson Python Airlights that came stock on my xtc2. I swear those things have thorns pre-installed on the inside. They are shocking.

Hutchinson Scorpion Tubeless here, big and heavy ones :) I've had a couple of flats with them (from very large objects penetrating the whole tyre) but nothing compared to tubed tyres with the pinch flats you get from those. They've done well for me and had no trouble with them, UST rocks !
