[Regarding our Bicycle Parts Trade-in/Purchase Service]
"We want to deliver products that can be cherished and used for a long time."
With this in mind, Grumpy proposes bicycle products every day. In addition to providing items that can be used for a long time, we also focus on repairs and maintenance so that what you already own can be used even longer.
However, the world is still dominated by mass production and mass consumption, and things that can still be used are disposed of, and even new items are discarded as unnecessary. I believe our lives also contribute, to some extent, to the waste of resources and environmental pollution.
In such a situation, is there anything we can do? Perhaps it's part of the culture surrounding bicycles, or a part of our business as a bike shop. After much thought, we decided to start by increasing our handling of used products!
This is because I realized anew that used products themselves contribute to using a single item for a long time and carefully utilizing limited resources.
What is "unnecessary" to one person may be "necessary" to another. For example, do you have a bicycle at home that you no longer use? Do you have leftover custom parts at home, a broken derailleur that no longer works, or junk items like a stem with rusted screws that you don't know how to dispose of? Is there anyone like that?
Do you want to build a bicycle but want to make it a little cheaper? Do you want to use high-quality parts even if they have scratches? Do you need replacement parts to repair the parts you are currently using? Is there anyone like that?
Grumpy acts as a bridge for such people, offering trade-ins, purchases, and sales of used products.
【About Trade-in/Purchase Methods】
You can choose from two methods for trade-ins and purchases of bicycle products: ① In-store appraisal and ② Shipping appraisal.

② Shipping appraisal
This is a method where you ship your bicycle products for trade-in or purchase.
Please use this method if you wish to trade in or sell from a distant location.
We will provide a preliminary appraisal via the inquiry form in advance, and after the product arrives, we will conduct an official appraisal and inform you of the final amount.
