DC | Subject: How much faster are Conti GP 4000s Seen/read all the data (including on this awesome forum) & these tires rock. I get it. Still, what does all this mean for, say a 40K TT. Victorria Rubino Pro's are less than half the price! Having recently upgraded my tri & roadie wheels (Flo 30' & 60's), i.e., sleepoing on the couch, I am wondering what the extra cash will get me, i.e., is sleeping on the porch worth it? The best tire I've used (trained/race) the Michelin P3's. Huge ride quality digference from, say, Victoria Zaffrino's. |

Champion 6503 NOVA - Ironic for an Endurance Athlete | Subject: RE: How much faster are Conti GP 4000s I'm not sure, because 3 years ago my (much faster) teammate put a ton of research time into tires before IM CDA and basically 11 of us made the move to Conti GP 4000. Never looked back. Durable & fast. What else matters? |

32 | Subject: RE: How much faster are Conti GP 4000s When you buy the tires, get them from the uk. on sites such as probikekit.com or wiggle.com They will take about a month to ship but if you buy them soon enough and just stockpile them your good to go. Why pay 75$ in store when you can get it right now for 39$ a piece. I check every so often and when they go on sale i have gotten them for 34$ a piece. Now i am a huge proponent of supporting local bike shops but for this huge of a difference I'm sorry. I have used this site and others plenty of times and so have a lot of my buddies. Its worth checking out. and will save you probably 60-75$. Here are the tires for 39$ http://www.probikekit.com/bicycle-tyres/continental-grand-prix-4000... |

I don't know how much faith I have in the actual speed number because it ultimately comes down to how hard I am pedaling and it's nearly impossible to keep that variable static when you're talking about a variance of ~5-10 watts but you can just plug your numbers into a site like bikecalculator.com. It'll at least give you 2 numbers for comparison. |

Wow, a month!? It is variable. I've gotten them as quick as seven days or as slow as 28. I think it all depends on whether some customs inspector decides to look at a shipment...... |

I've bought several 4000S's from PBK also. 4 days (yes really) to about 3 weeks has been my window. I'm on East Coast. |

I just picked up a set of Continental Grand Prix's for $35 each, but they don't have the 4000 designation. Does anyone know if these are a similar tire? |
