I’ve been researching the differences between the Shimano RD-TY500 and RD-TY300.
RD-TY500 and RD-TY300 are the same TOURNEY series rear derailleur’s.
What’s the difference? We looked into it.

model number
Except for the three-digit numbers “RD-TY500-SGS” and “RD-TY300-SGS”, all alphabetic characters are identical.
Maybe, it is the same TOURNEY series, but the model number with more digits may be higher version. The reason is … only RD-TY500-SGS has “Wheel Type Cable Guide” (to reduce resistance of inner cable).
You will find explanations on the following pages.
Wheel Type Cable Guide – Shimano
Product Specifications
We compared the “Product Specifications” on the official manufacturer’s page.
The only difference in the product specifications is that it is available with or without the “Wheel Type Cable Guide”.
Appearance differences
I can clearly see that the RD-TY500-SGS has a guide pulley and the letters “6/7SPEED SHIMANO” have a white background and black letters. Maybe there are some minor differences, but I couldn’t tell the rest.
Price Difference
Amazon prices (as of 5/29/2022) are…
RD-TY500 1,527 yen
RD-TY300 ￥1,391
This was the result.
What’s your experience with the RD-TY500-SGS?
I replaced the minivelo (talk about customizing a minivelo (Bridgestone F6F) to single speed) when I asked for an overhaul.
The overall impression is bigger than the Tourney RD-TY21 I’ve been using. The pulley is also bigger.
I feel the shifting performance is smoother and lighter than RD-TY21 with “click-click-click”. It may be the effect of the “wheel type cable guide”. The shifting lever is SL-TX30-6R.
