From a friend that worked for a wheel manufacturer. Tire making is a super precise art. Bad tires are really bad because it means that the molds etc are off.

Rim manufacturing (other than molded carbon rims)? Not so much. Extruded tubes, looped, welded, and ground down so they appear straight? Talk about crap manufacturing tolerances.

The pre-machined-sidewall Mavic rims (and probably others) were extruded from some normal pipe, it's like the Allen trunk racks using electrical conduit piping to make trunk racks. Mavic, as the demand dropped for their rims, couldn't use the mega-length rolls of pipe so they had to start making rims like normal. They developed the machined sidewall so that the apparently "not-very-straight" extruded rims would be "true". Now machined sidewalls are the norm.

Well, I believe that all of Challenge's tires are hand made. Meaning, yes, the tread is made in a mold, but it has to be glued to the casing by hand. Same with the stitching, etc.

For "normal" vulcanized clinchers, yes, it's very precise. The only bad tire I've ever had was a Continental that was part of a known bad batch. Hundreds of complaints, all over the internet.

My bad. I didn't read the "tubs" part. I take back everything I said about precise art. :)

Vittorias are really solid and if you look around, not too expensive. I've got some Stinger 3 tubie wheels on the way to me now. Looking forward to racing them.

Anyone have any experience with Specialized tubulars? I need a new tire and I'm normally a Vittoria fan but my team shop is a Specialized dealer.

revchuck 03-04-15 05:39 PM

I'm currently running Specialized Espoir tubulars on my TT bike. They're my first set of tubulars; I got them because they're cheap and I didn't want to mess up expensive tires my first try mounting them. They're solid and actually ride pretty well. I can't comment on how well they corner, but they do use the same tread compound as Specialized's race tires.

Well I just jumped off the deep end and decided that my tax refund would be best spent on a new bike. My shop that I have personal ties to basically got me a beyond smokin deal on a new Felt AR2. Now I can go do my tempo in style. The handlebars I am sort of split on, I like short and shallow drops but it is coming with Aerotundos (Traditional drop aero style bars), gonna see how they feel, may end up deciding to hand them off......anyone got some interest?

shovelhd 03-06-15 08:50 AM

Welcome to the Felt club. I love my FC. I would be interested in the bars If they were 40cm.

dz_nuzz 03-06-15 09:16 AM

I think they are 42s. I also want to try them since I have never ridden standard drop bars before but if I hate them I am going to swap back to some good ole trusty ergonovas. I will shoot you a PM if I decide they aren't for me.

grolby 03-06-15 09:52 AM

Yep, were they 40's I'd have been interested. Alas for me.

BTW, I have some Ergonova's lying around that I took off my cross bike, if you're interested. They're 40's though, which you might find a little narrow. Nice and aero though!

dz_nuzz 03-06-15 10:14 AM

I have an older set of 40cm Ergonovas and just picked up a set of 42cm ergonovas at the swap. Sorry buddy.

Traditional bend with flat tops?

shovelhd 03-06-15 12:10 PM

Yes. Anyone getting rid of 40cm bars, are they carbon?

Yes.

I will want to try them for a bit before I make any decision.

love my rotundos; aero version sounds cool.

will they help me win??

shovelhd 03-06-15 02:05 PM

Only Fudgy can help you win.

echappist 03-06-15 02:34 PM

i can get people a brand new aeronova team handlebar for ~250 shipped. PM me for details

for aerotundo, some guy (not me) on slowtwitch was selling one for relatively cheap (~$230 ish). also PM me for details.

Ygduf 03-06-15 03:34 PM

buy your handlebars off ebay like I do, then when they are broken and you build the bike up on the old bars you've saved $230.

Nuts. Funny thing is I could actually use 42 cm Ergonovas, they run so narrow. Anyway I'm sure I'll be able to do something with my 40's.

Looks like the Aerotundo is substantially different from the Rotundo. The reach is much longer.

Holy crap, 113mm reach!? AEROTUNDO TEAM - Dropbar - 3T Cycling Road

Anyone used this Park Cable routing tool? I sure could have used something better than my coat hanger.

I think next season I'm going to 40 bars on my road bike. Going to try 38 on the track bike this year.

I switched my parlee from external to internal battery this year... pretty much had to rewire the damn thing more or less. I used a heavy fishing type weight to get it down the seat tube down to the BB area.

mattm 03-06-15 09:22 PM

Took my bike into the shop; turns out the derailleur hanger was bent.. no wonder I could never get the derailleur adjusted quite right!

May or may not explain the mystery chain drop, but it can't be any worse.. (I hope)

Mechanic joked that people are usually either a good mechanic or a good bike racer, and that I must be a decent bike racer.

I have some PRO vibe carbon bars (round) that are 40s. Been meaning to sell them. Super solid, they are.
