@robotdave: the first response for this one (regarding aluminum) in your link is a 3 year old NSMB forum post that says this: I have never changed bars because of a concern about failure, but I am a chronic bar swapper, trying to find a perfect fit. I'm also a mechanical engineer, and do a lot of work with aluminum fatigue. I can't guess about how aluminum handlebars are engineered, but aluminum does not have a fatigue limit, so it will eventually fail under very low cyclic loads (e.g. normal riding). That said - I would guess anyone designing bars is running FEA on them and has a life criteria (number of stress cycles to failure). Any reputable bars are also going to pass ISO 4210-5, which is the ISO spec for "bicycle steering equipment." Part of that standard is a fatigue life test on a bar, which is usually to 10 million stress cycles (unloaded -> loaded -> unloaded under the force generated by a "severe user"). Short story: yes, aluminum bars will eventually fail, but it will probably take a long time unless you are riding pro-level DH all day every day. If you want to be safe, replace them once a decade; 3 years seems very short given that there are a lot of older bars out there and they do not fail if you look at them wrong. If you damage the bar in a crash (visible gouges, which are stress risers and will decrease the fatigue life in that spot) or get hit by a car (forces much much higher than the bar is designed for) then I would replace them.

@robotdave: they do! or did, i have a 11-50 sunrace 11spd HG cassette that replaced my 11-46 xt cassette. i think it might be hyperglide though.

@Grosey: i mean it literally has 75 times the amount of power as the spesh, so it's probably safe to say it's a little faster.

I waxed my skis this weekend instead

@Fix-the-Spade: Moose mountain and Canmore are both less than an hour away... come ride Razor's edge and try it out

@andyelliott3: @andyelliott3: Agreed, however even on YouTube you need a reason to make a video, and WC racing can be a great subject. take Redbull race recaps or any of the factory team videos for example.
