2018 PRO thread
Moderators: robbosmans, Moderator Team
I find the tech/bikes the pros are racing more interesting than the dope they are using, yet the doping aspect gets discussed far more in this thread. But it’s still all pro racing related, so to each their own. No one is preventing anyone from discussing the latest races going on. Not to worry, Le Tour is just around the corner. Things will shift again.

My bike has 435mm chainstays. On a full suspension MTB. Given that it has tires that are 60mm+ taller in diameter (743mm) than those on my road bike (679mm), your argument doesn’t make sense. There are 29er MTBs with and much shorter stays (414mm, for example) that can accommodate the same size tires.Calnago wrote:Of course they do, and that’s what long cages and long chains can take care of just fine. But how long are your mountain bikes chainstays? How much clearance is there up front between tire and whatever obstructions might be in the way. What is the BB drop on your mountain bike? I’ll bet all those things are quite different than on the 3T road bike they’re trying to run 1x on. And those differences all contribute to the problems AquaBlue is having. Either in the form of bad chainlines at the margins which adversely affect shifting or clearance issues which adversely affect speed of wheel changes. Also, what is your average cadence on a big technical mountain bike ride. Probably lower than your average cadence on your fast road ride. I seem to have already said all this when you posed the question before about the differences inherent in mtn bikes versus Road Bikes. The two have different requirements in so many respects. Why don’t we just have the entire peloton on mountain bikes then. That would solve everything.

So are you planning on contributing something more “relevant”...?
Makes total sense. Discussing two separate issues, potential for chaindrop and ease of wheel changes. 435mm is a huge chainstay length compared to the 405-415mm of the typical road racing bike. In the context of chainstay length, longer chainstays ease the chainline a lot. Even a couple millimeters can make sometimes make the difference between go and no go when it comes to a good chainline at the extremes. Your 435mm is like 20mm longer than a longish road bike chainstay. The shortest example you come up with is 414mm... which is at the longish end of a road bike chainstay. AquaBlue's chainstays are only 405mm and they wonder why they're having issues? Actually, I think they're fully aware of why they're having issues.LeDuke wrote: ↑Thu Jun 21, 2018 1:09 amMy bike has 435mm chainstays. On a full suspension MTB.

The clearance and BB drop differences between road and mtn bikes have more to do with quick and easy wheel removal verus chainline and the possible resulting chaindrop issues. I've described all this prior but I guess you didn't get it first time around. Maybe a reread if you're really interested is in order.
And lastly, I’ll be damned if I’m going to ever ride a “road bike” with 435mm chainstays. At that point it’s not a road bike anymore, well maybe you can ride it on the road, but that’s about it.

Again: WC XC racers often have much faster wheel changes than what I see happen on the road. So the problem is the personnel, not the equipment. If you can’t change a disc wheel in under 25 seconds, you aren’t good at your job.
Re: chainstays, they are a function of suspension design and desired performance traits, plus mud clearance. On a hardtail, sub-400mm is regularly done by custom builders. On tires ~25-30mm larger in radius than a 25mm road tire. There are 29x3.0 bikes with 415mm chainstays.

You're right, opinions differ, but at the end, lots of blah,blah talk about doping and bike tech,..Calnago wrote: ↑Wed Jun 20, 2018 11:59 pmI find the tech/bikes the pros are racing more interesting than the dope they are using, yet the doping aspect gets discussed far more in this thread.

Don't forget, before the Tour ( and like you say, a new chapter of the huge novel will start again there...) it's national championships weekend now in many countries .

There just isn't much innovation in road bikes. People rarely take any risk and aren't willing to make mistakes and learn from it. Mountain bikes have undergone some growing pains at times, like when 29ers first came around and handled/rode like giant boats. 1x is another great example as are a billion suspension tech trends, but manufacturers and riders learn and move on. I applaud 3T for even trying and don't trust a tweet by an angry pro to inform us as to what happened when there isn't video evidence. It's pretty easy for people that are emotional to make up parts of narratives that don't happen.
So hopefully we can move the *f##k* on from this circle jerk and find something else for the next few weeks until the Tour.

Hinault saying the riders should strike if Froome lines up for TdF. Big words again from the almost certain ex doper!
exactly. why not, istead if complaining about certain topics, post stuff you feel belongs here
re: 1x
I just left my bike at lbs' for a day and got a replacement rig: Focus Paralene 1x I'm going to clock some kms on her today just for kicks, but the initial feel of SRAM's Apex 1x is not very road-ish. enough for rocking that bike path though...

A guy in our bunch turned up on a paralane last year- he sold it the following week. I think it was because of the threats of throwing it off the nearest cliff
