DNP 7 Speed Screw on Freewheel Nickel Plate 11-34T, ST1781

This is the sort of thing that you just hope will turn up. I've a rear wheel with a screw fitting for the gears and was reluctant to spend the money in order to buy another wheel with cassette fitting. What I wanted was a good range of gears and this fulfils that criteria with a low gear of 34 teeth and a high of 11 teeth. The product looks good, fitted perfectly and is a real dream when changing. At this price, you have to expect a few burrs on the teeth before you run the item in. This is because the gear are drop-forged and on the more expensive models, the burrs left by the drop forging are removed. However, a two-hour- bike ride using all the gears fixed that and this items runs as sweet as a nut. I am very happy and can highly recommend it. Good for DNP for filling that hole in the market.

On the beginning after I changed this Freewheel the chain start to skip on some gears a lot, but after changing chain as well everything stabilized and work very well.

Worked great on my Lectric XP 2.0 to add more pedaling resistance at higher top speeds. Even has a little resistance in parallel assist 5 mode. Perfect amount of resistance in pedal assist 4.

Nothing at all.

シマノの１４－３４の７速スプロケットからの交換です。当方の２０インチ折り畳み自転車ですが、効果あります。巡行スピードが４～５km/h上がり、ちょっと頑張れば３３～３５km/h巡行できるようになりました。取付時フレームと干渉するためスプロケット側にスペーサーとしてワッシャーを1枚かませたりちょっとした工夫入りますがいい感じに仕上がりました。

Low quality product. Teeth were uneven and some with the shape of a shark fin. Ractheting mechanism seems poorly lubed. Was expecting a higher quality product given the price. It is a shame as the gear ratio was interesting. Returned without any issue.
