I ordered this derailleur for my husband's bike. He has since purchased a higher end model from another company.According to him, this is a basic, entry level derailleur. It's a good choice for a generic big box inexpensive Chinese bicycle. It does the job, mounts easily and the arm swing is enough to move the chain between the chain rings. However, it's machine pressed and inexpensively built and he wanted one that's more upgraded.This is an average, ok derailleur that's priced well but it's just average.

I got this to replace a tiagra triple that had become very loose and was impacting shifting. although rated for 6/7 speeds, tourney will function with up to 9speed systems without issue. the width of 10+ speed chains is narrow enough that the wider cage on the tourney can fail to shift properly, although it can still work with certain setups. I believe some companies changed the cable pull ratio as well.regardless, I'm impressed at this FD's all-metal construction and quality of manufacture.

I was going to replace an old derailleur with this one. The old one wasn't broken, just dirty and scratched up. But I decided not to do that, because I think the old one is better.Why, you ask. My first photo shows the clamps of the old (silver) and new (black) derailleur next to each other. The old one is 1/8" or so thick at the thinnest, and thicker at the hinge and the bolt ends of each half, and the edges are chamfered (rounded). This new one is a much thinner, and the edges feel rough. Why does that matter? This clamps onto the painted down tube of your bike, and that rougher construction is likely to scratch up the tube (particularly if you don't get it positioned just right initially, and have to wiggle it around).My second photo shows the two derailleurs side-by side--I guess it's obvious which is which. What surprised me is that the old one (and every other front derailleur I've seen) has a screw holding the two sides of the cage together; this allows you to slip the chain out for cleaning or un-sticking it (like if it slips off the gears and you need some slack to get it un-jammed) without "breaking" it. The new one just has a rivet there--no way to get the chain out of this derailleur without breaking the chain.Not sure what I'll do with this derailleur, but I'll be cleaning and lubing the old one and putting it back on my bike.By the way, I was perplexed by the description of these derailleurs as "up swing" or "down swing." I've never seen those terms before; most front derailleurs are described as "up pull" or "down pull" (meaning the control cable pulls from above or from below) and "bottom swing" or "top swing" (depending on whether the cage is mounted to the bottom or top of the four bar linkage, which in turn means above or below the clamp). I'm still uncertain what "up swing" or "down swing" means.

Replacing the original worn-off Shimano Tourney TY300 on Trek Precaliber 24. This comes in OEM packaging. Perfect retrofit and noticeable improvement in shifting. Easy to install.

Just as easy to install, as durable, and fits as any other. Good value and should perform just as factory.

Not a bad clone/knockoff. It's actually almost indistinguishable from an authentic one except for two things. One, it comes inside a padded envelope and not a Shimano box or any kind of box really. And two, the stickers are not right. Search FD-TY300 and notice that the real FD-TY300 has two stickers whereas this clone just combines them into one sticker.With that said, the price is unbeatable and it's worth giving this clone a try especially if it's for an older bike or one you're fixing up and selling.

I've been searching for a new front derailleur for my vintage 10 speed bike (1973 Nishiki). Unfortunately, this one doesn't mount onto my vintage bike's frame without severe modifications (which I won't do). Still, it's a quality derailleur, and should work for anyone seeking a new front derailleur for their bike ... provided it mounts the way this one does. One thing I miss on the "modern" derailleurs is the screw post that holds the two strips of metal together at the rear of the derailleur. With that screw post, you could actually change the derailleur without having to break the chain, just by unscrewing that screw post. Derailleurs today are mostly pressed together, forcing you to break the chain, or modify it to put in a screw post. This one is no exception.
