Yes, the bike's got oversized handlebars now that are relatively if not completely straight (flat) and a short heavy duty stem. It's also got disc brakes so the lines I think will need to be extended and bled which I heard was very expensive. Since I think you cannot just extend brake lines, they would need to be removed and new longer brake lines put in its place, correct?
I just need to make sure if I swap it out for something new it can support my weight as the rig now is really pretty heavy duty. Are there certain brands that are known for heavy duty handlebar/stem combos?
With regard to just changing the stem, I was told by a bike shop it might be difficult due to the weird handlebars he's got - some sort of non-standard size I guess - thicker in diameter than standard.
