Hello all! I need help. I have no clue how to determine what type of handle bar I need. I have a Trek7300 that has not had any personal changes on the bike except for spd petal. I have taken up doing long rides and I have had a problem with my hands going numb. I changed the position of the handlebars but that has not seemed to help. I want to add bar ends to be able to change my grip for longer rides (30 +miles) and I am not in the market for a new bike. I have added new grips and wear gloves but after 25 miles I still get tingling. My current setup has gripshifts and the ergo-grips but I cannot fit any more gear on my bars. The bar is a bontrager with this obnoxious bar for hooking up their gear and I think the trend faded out as I can't find that stuff anymore. I am curious if I need to get a new handle bar to fit in the bar ends, or is there anything else I should do (such as switching up from my grip shifts). Any feedback would be awesome. Thanks alot for any help!
Peace,
Sean
