Do you have a crank that's easy to replace, like Shimano Hollowtech 2? It's actually easier to exchange those than chainrings. I usually ride a road-compact (50,34), but for long tours around the alps I exchange them for a MTB one (44,34,24). I have a non-indexed front-shifter, so I don't need to change settings. Triple crankset axis seem to be some 3mm ...

I would underscore taking it to a trusted local shop to remove the bunged screw. But I would also suggest that if you've tightened the other four that your creak is NOT coming from the chain rings but probably from either your pedal, your cleat or your shoe. Also if you haven't lubed the chain for awhile you can try that as well. A creak from the ...

Personally, considering the cost of a replacement crank and/or chainwheel, I'd probably take the bicycle to a trusted local bike store and pay them to fix my mistake. If you make it worse, that's false economy. You could slot it with a Dremel, but before I did that I'd try a Torx bit first. Sometimes it is possible to force a Torx bit into a stripped ...

I think it's the trimming function on STI shifter as you have a Tiagra shifter set (at least in the UK) You can adjust the front derailleur's adjusting barrel and move the derailleur a little bit to Low, so that it wouldn't rub on the chain when it's at trim level. Then you adjust the Low limit screw to make sure it wouldn't swing the chain off the small ...

You could try using a brand new hex key, some brands may be slightly larger than others. You could see if a slightly larger non metric hex key, or hex key bit can be hammered into the recess. For example, a 7/32" hex key is about 5.6mm. I believe some nicer metric hex key sets come with 5.5 mm sized keys. If you can buy or borrow a dremel tool, you might ...

First, are you really sure the crankset needs replacing? Maybe you just need new chainrings. It takes a lot of riding to wear out a crankset, like 10000 kilometers at least. If you've done enough riding to wear out a crankset, you will likely need to replace the rear cassette and chain at the same time. If you are maintaining the bike at all, you should get ...

You'll need a new bottom bracket with a different axle length, a new crankset of course, front derailleur and matching shifter. Since you'll probably need to buy a complete set of brifters it will be quite an expense. And while you're at it you'll probably have to get new cable housings and cables for the brakes. Not to mention new bar tape. At least you can ...
