Hi all, I'm unfortunately one of the few TM01 riders that has been affected by this issue. Specifically, I was thrown over the bars three times over the course of a six week period. For those riding with 25mm tires, please for your sake, DO NOT take the chance.

I was completely confused at first as to why this was happening and thought that I maybe had something to do with it, but BMC reassured me after the second accident that the issue had been resolved. It wasn't until my third identical accident that a BMC corporate manager reached out to get a full picture of what I had gone through.

To note - all three of my accidents happened upon moderately applying both the front and rear brake simultaneously. I can't possibly explain how the frame and tire can flex to such a variance, but the front wheel immediately locked against the downtube and forced the headset cover upward (as detailed in the photos).

As stated above, BMC is in fact working on a fix for this (a modified fork to be precise) that apparently will be out in September. They've been kind enough to provide me with a TM02 to get me through IM Lake Placid but this still leaves me wondering whether this solution is in fact just. Please I'd love to hear what you all have to say.

While I appreciate the predicament, I have to admit that it is frustrating to see that this recall is only voluntary and that they are giving discretion to riders based on the tire size they are using. Please shoot me any questions should you have any

Oh man, this looks pretty bad. I hope you are okay and didn't sustain any injuries with this.
I am very surprised that this tolerance problem happened on such a premium bike that has been ridden by two pro teams (most of them are running 25mm tires too) for almost 2.5 years now.

After doing a lot of research, it looks like there has been quite some accidents actually where people got injured and BMC had to do the recall after reports started piling up. BMC still are being vague on the details for what exactly can happen and how to avoid it.
From what you are saying, it looks like it is a stopping power problem, when the whole bike is "squeezed" the downtube/fork/wheel get very close and end up causing this tire/downtube contact.

How fast were you going when you were braking? was it downhill fast speed or a moderate speed. Also, can you let us know what tires were you using?

Another thing is that according to BMC, worst case scenario, you can run 23mm safely (after headset being adjusted), why did they send a TM02 frame if the problem can be resolved with a new set of tires?

Sorry to be asking a lot of questions but i am very worried and i have an IM race this weekend, considering going for a regular road bike and not take any chances.

This post got me also very alarmed, apparently someone from Brazil also got knocked off his bike and spent sometime in a hospital,
its bad enough that we have to worry about safety with traffic, but now we have to think about manufacturing failures too.

in the second post, it actually shows the frame cracked after the contact. so it isn't just headset issue.
From earlier posts too, it looks like they ignored him for quite sometime before owning up to it.
