DNP 7 Speed Screw on Freewheel Nickel Plate 11-28T, ST1780

This was a perfect match for my Lectric XP folding ebike! Great upgrade allows for less pedalling at higher speeds.

Works great on my e bike when motors topped out I still have 2 more gears 4 ma gams

Two words sums this up. KICK ASS!!!

This Freewheel did not fit on the bike; the spacing between cogs was not uniform! The company offered a return but the shipping cost to china was more than the item was worth. The company responded quickly but you are dealing with a poorly made product that you can not return. This is the new Amazon.

Too many skip on the cogs,not so durable..

Much thicker than the stock one that came with my new Ebike and definitely helps to slow down your peddling cadence attempting to use oeddle assist that most e bikes have..

works great

As advertised! Upgraded my XP Lectric & very satisfied.

今までの最少14 T、7段が壊れたので付けてみました。 取り外し工具等は別に購入の必要がありますが、古い物を入れ替えただけですがトップスピードが上がり満足です。（平地でもこぐのは少し重くなりました） 軽さは持った感じではあまり変わらない気がします。耐久性はこれからですが先ほど５㎞ほど慣らし運転した感じでは問題無いようです。（最初は馴染んでいなかったのか少しカラカラなっていたのですが今は問題なく使えています） 今後のチャリンコライフが楽しみになりました。

Bought this to replace my 14 - 28 because i converted my bicycle to a 250w Ebike. The original 14-28 gearing was too low, and I found myself ghost peddling. So, I bought this 11-28. I did not put a new chain on. As others had reported there was grinding and slipping so i thought I'd cycle it for about 40miles to wear it in. There was an improvement but still 11 grinded or slipped. So, i put on anew chain. The moment i did everything fitted and ran smoothly. I should have known this from driving motorbikes where you always change the chain as well as the sprockets. So, when buying include a new chain. Otherwise seems to be working fine now and no more ghost peddling.

Gearing is great. Easy to use. Fun to train with

The DNP Speed Screw ON freeWheel-casette didn't by any means fit My Chain!? Even though this Chain is a Shimano for 7-Speed Casette... the chain Just "rattled" over the Teeth!? - in the 3 Highest gear-sprockets!? Only the lowest gears was functioning? I Do not know What's The Reason for this Behaviour? - Searched the net for an answer? Or TIP to Stop it from Doing this? I Consulted trustworthy Bicycle-folks deling with Gears every day..!? Noone seemed to have an answer? So - for ME . buying this Casette was a Flop!! K.R.'s Update: I found a site knowing of this problem? And as I read the advice regarding the DNP-casettes behaviour, I had to pay attention to the B-screw!!..! I did!.. and setting the Deraillieurs upper trolley-wheel as close as my Derailleur allowed??!.. the things changed drastically to the better!!..! My deralleur though (Shimano-Deraillieur) didn't allow me to get as close as I would want to. To get the chain as close as possible to the sprocket?.. So? There is!! A little tendency still to "skip/slip over" the sprockets teeth in the very highest gear (smallest sprocket!) Still?.. But regarding the way it behaved before it's a huge bettering!! K.R.'s!!

ターニーと組み合わせると、キャパシティを超えてしまうこともあり調整必須です。通勤用バイクで雨の日も走るので条件は悪いのでしょうが、3000㎞程度でよく使うギアが歯飛びするようになりました。耐久性はシマノより、かなり劣ります。
