You could possibly fix it with a shorter stem, but… actually, just take the bars off and sell them to a hipster. Look at the picture above, and imagine where your centre of gravity is when riding with the original bars. Then where it would be riding on the horns of those bars you’ve fitted. Now go and get the bullhorns off your bike, take them somewhere safe and set fire to them.
Unless your torso is way too long for the frame, that’s going to be super-uncomfortable. Stop thinking about which bars you *want* for it, and start thinking about which ones are going to be the most comfortable. With bullhorns, you’ll have a position like Graeme Obree’s – fine if you only ride track, not so good if you’re riding anywhere else. As this bike was specced with a flat bar, and you’re using the existing stem, your hand position on the horns will be a good 6-8″ further forward than the designers originally intended. Not good.
As a general note – look at the numbers for a drop bar bike and numbers for a flat bar hybrid like the one you have there. The TT length, forward centre and headtube length are the key numbers here – and you’ll find they tend to be a little different.
Great point… unfortunately your completely wrong.
Its not your fault tho, your expecting Chrage to have designed the bike for flat bars, when infact they have just taken a stock road frame and fitted flat bars. The effective TT on the Large is only 575mm FFS! Thats cramped even with drop bars or bull horns.
To the OP, bull horns are a weird proposition, most people hate them for their looks before they even realise they are uncomfortable. If you like them great, but you’ll not find many willing (or able) to give you support in setting them up.
