Here is a pic guys - tweet it if you can as well please, thanks

the problem with that is; if they realise the guys are riding with guns, they will shoot before you get off your bike, they wont take the chance of getting shot.. It wont stop the guys, it will make them more eager, they can get bikes, cell phones, guns etc from cyclists...

Yeah thats it..

They know to turn off your phone if they do jack you...

This seemed to be a preplanned hijacking - the exact spot was close to the old Boschkop bike park - there is a single track that goes up away from the bike park to the right, you go through a little gate, there are 2 sloots you have to get over, it then goes up to a small road, over a cattle grate to get the main road again.. they were waiting at the top of the single track..

2 guys had sunglasses and leather baseball caps... he will post some pics of the bike tomorrow.... he seems ok we need to find a way to sort this out, cant be afraid to go out riding.. crime is making our worlds very small...

Hi All My friend was hijacked this afternoon in Pretoria east - we was out close to rosemary hill on his MTB. as he approached the rosemary hill road, he saw a Vito bus without plates parked on the side of the road.. 3 guys jumped out and had guns and knives, they took his bike, glasses etc, tried to get his cellphone, but convinced the he didnt have one. the stole his Cannondale Scalpel, medium, Mavic SLR rims, Carbon lefty etc.. Will get him to post more details on the bike. Be carefull out there guys, the east isnt as safe as it used to be.. watch out for Vitos without plates..

posted this yesterday - it explains the rolling resistance specific to bicycles tyres.. http://www.mtbonline.co.za/info/mtb-tyre-rolling-resistance.htm

if you leave it long enough, it will form a nice goooeee blob in your tyre... try spin the tyres from time to time if you arent riding, but you will need to replace the slime at some stage anyway.. so it all depends on how long you leave it for...

an extract As soon as you leave the road, reducing tyre pressures does not just leave rolling resistance more or less unaffected, as can be heard here and there, but actually reduces rolling resistance! This is true even on level paths of fine gravel, but the rougher the ground, the greater the effect, as the grassy ground shows. Reducing tyre pressure from 4 to 1.5 bar (57 to 21 p.s.i.) can save an averaged 20 W! The main reason for this is the unevenness of the ground. A tyre with less inflation can adapt to unevenness more easily. The total system needs to be lifted to a lesser degree and less frequently. Resistance is reduced, less power is required. Off-road a reduction of tyre pressure reduces rolling resistance. In a meadow for instance going back from 4.0 to 1.5 bar (57 to 21 p.s.i.) can save remarkable 18 Watts of power.

Take a look at this article, it depends on what terain you ride... on tar higher pressure reduces rolling resistance, on gravel the higher the pressure the more rolling resistance... http://www.mtbonline.co.za/info/mtb-tyre-rolling-resistance.htm

keep it like that - nothing sexier than raw carbon... well nothing on a bike anyway..

pics?

Eventually got me a new lid for my pip... Rudy Project - Windmax 220 grams - Nice

you should be able to use a 26er wheel on the back with a normal trainer.. just get the same type of cluster and a slick wheel...

for all the Cannondale fans out there, check out the 2013 range - some nice stuff. http://www.cyclingnews.com/features/photos/eurobike-2012-tech-2013-cannondale-highlights-for-road-and-mtb/238506

some hate mail may be in order - mark@marktheshark.com

That whole section down to the golf course is singletrack...

No access issues, but you cant park at Groenies and get through.. well you can park there and pay, but then you gotta go out the gate and all the way to fountains circle and up.. you dont need to pay to ride Klapperkop, its open

hub is so busy, dont think it even featured for a second on the latest forum posts

Hi All Just though I would share a (new to me) route, you may be aware of it, not sure why it took me so long to figure it out. It’s not long at all, only 8.75 km, but it has 264m of climbing in the route max 18% gradient. A few loose rocky bits which are really tough. Give it a bash sometime if you have not yet ridden it.. Try 3 laps of that and you will know you have done a ride.. I have plottted it in reverse, so just do it the other way.. Clockwise enjoy Pm Me your e-mail address for the google earth .kmz file, cant upload it..
