"Bas items"
"When you have a Bosch powered bicycle and you want to do tune-up, you must have this tool in your kit."
"Must need tool for service work, change chain rings etc. From the store that knows what you need. Arrived on time. Will order supplies from here again."
"Shipped quickly and price was right, I was experiencing chain suck after putting on a new chain, to install a new front chain ring to solve the problem I needed this tool. Perfect fit, definitely a genuine Bosch tool."
"great service!"
"Had what I needed in stock, quick delivery. Quick answers to my questions."
"What can I really say about something like this? it’s a simple spider tool that is required to open up a fairly low torque lock ring. Not a very demanding application but it works so I guess that’s the end of story."
"Ordered a tool for my Bosch Electric system. Ended up ordering additional parts from these guys. They are great!! I know I will be working with them again. Thanks!"
"This is an original from Bosch not a cheap replica."
