Extreme Veteran  1942     In front of computer when typing this. |  Subject: Power optionsI've looked around and it seems that there are two main options for power meters: crank-based ($$$) and hub-based (less $$$, but still $$$, so lets say $$). Crank-based, to me, seems ideal because you can use it regardless of your wheel choice (racing and training, if you have designated race and training wheels) since it is tied to your crank. Is there a less expensive way to get power when training and racing (on different wheels) without having to buy a crank-based system or two powertaps? I guess you could change out the hub when you go and race, but that seems like a lot of work (is it?). I could be way off on my assumptions but that's my rudimentary understanding of it. Am I wrong? Thoughts? |

Champion 19812  MA | Subject: RE: Power options You are right. Changing out the hub between race and training wheel is not practical. Cheapest option, find used or cheap PT, buy a wheel cover for it. Most flexible option, buy a crank based system and lower cost is CinQo Quarq then you can use variety of wheels, variety of ant+ power head, and also can change the batteries at home. |

Master 1439 Calgary, AB Silver member | Subject: RE: Power options Unless you're in a draft race, or Kona, a good training wheel with cover is going to be equal or better to virtually all "race wheel" options - and you get your PT all the time, trainer, training, racing. And it's the cheapest option as well. |

Master 2094 | Subject: RE: Power options I picked up a used wired PT and can't be happier. I have seen a huge improvement in my cycling. I had wheel covers and personally didn't care for them. I use a disc for racing and follow HR. I use the PT for training. It is a bridge for me until I decide it is worth the $$$$ for crank based or the price comes down. |

I like the idea of training and racing with power...makes sense to me, although just training with it is prob better than nothing. Crank-based systems are a tad expensive! |

| Subject: RE: Power options couldn't you just sell the 101mm rear? The disc cover will likely be as aero, if not more aero. |

The disc cover will likely be as aero, if not more aero. I COULD do that! I just got it though! My training wheel is not compatible with wheel covers either (Shimano RH500) so I would need to get a new training wheel. Not the worst thing. Good option though. One of my training buddies has the powertap/wheel cover disk option and it seems to work well for him. |

One of my training buddies has the powertap/wheel cover disk option and it seems to work well for him. That's basically what I did. I sold one rear wheel and replaced it with a used DT Swiss wheel with a PT and got a cover for it. By the way, you are probably going to be better off selling that rear wheel anyway, assuming you will want to race with the PT. Having a PT built into the wheel could get spendy. Your best bet, financially, would be to by a used wheel with the PT already built in. If you sell the race wheel, it could even be a break-even proposition. (It was for me.) |

| Subject: RE: Power options Yeah...what most people do is order the wheel with the PT built into it. Not buy the PT and build it into their existing wheel. So the fact that your current rear is shimano is pretty moot IMO. You can buy a PT Pro+ hub on ebay for like $900, but also go to wheelbuilder.com and get the same hub built into a brand new DT Swiss training wheel for $1050. Add in the labor cost for building the hub into your existing shimano rear, and you realize you're better off just buying the hub already in the wheel. The cost savings is minimal, and now you have a spare rear training wheel if anything happens to your new PT wheel. |

Elite 3315 Miami | Subject: RE: Power options another vote for PT + cover. originally i bought flashpoint 60 / 80...raced for 1 year. last year bought PT w/ velocity rim from wheelbuilders. last season i raced front fp 60 + pt w/ cover. its a freaking fast setup. once you get used to it its phenomenal. this season i will be racing Hed3 w/ rear cover+ pt. its the best and cheapest option. having a wheel will also let you change it between another bike if you have. crank based systems are also flexible but if you can change a crank between bikes faster then i can swap wheels well....lets just put it i won't be a happy camper. pt is also not necessary for racing. if you want to race with your 101mm.....although for a longer race 70.3 / IM its invaluable. |

Veteran 198 Chicago, IL | Subject: RE: Power options I bought a PT SLC+ laced into a DT Swiss RR465 rim with 32 DT Swiss Aerolight bladed spokes and alloy nipples. I purchased a Garmin Edge 800 for my head unit as I also wanted course info. With the ceramic bearings and 32 spokes I am hoping it will last forever. It arrived today from wheelbuilder.com... very fast build and delivery. |

Well, I suppose it depends on how long it takes you to swap wheels between two bikes (and whether you use the same cassettes on the two). |

For that price, you could get a PT on your training wheel and one on your race wheel. I just had to make this decision, and went with a PT. I can train and race on the same wheel (HED Jet 9). I wanted the use it on my road and tri bike, an don't want the hassle of swapping the crank. I'll put on a disc cover for races. |

But in any event, I don't run different cassettes on my bikes, and to me not having to think about buying different wheels for training and racing is a feature, not a bug. |

Elite 3315 Miami | Subject: RE: Power options i don't think i think its a bug at all and i see your point perfectly. in my case IF i wanted to buy a disc wheel right now, i have 2 options. Zipp or HED w/ pt which is insane, around 3k. so tot cost of quarq is worth it. but what i was saying earlier is i am never going to have HED h3 rear, Jet9, Jet6, Zipp 808....what would be the point, i am not a pro.
