hi i'm new to posting here. Ive had my Schwinn cutter for two weeks now its a great bike .but my problem is that Ive just bought a built set of velocity rims with surly hubs. i went home rode to work and 2 and a half miles into the commute i get a flat. call a friend to pick me up because i do not have the tools to fix the flat .get to work and look at the tire but no cuts on the tire it self.take the tire off and inspect it the puncture is inside between the rim and the tube like one of the spoke poked it but im looking at the rim tape and theirs no indication that there a spoke poking through the rim tape. so i put on the spare tire on after work and head home only to get 2 and a half miles in and here we go again a flat .take the tire off same puncture same place what going on am i missing something ? it has rim tape brand new i saw my bike mechanic put it on.is the spoke poking the tube? im a big guy i weigh 288 i am 6'4" bikes made for a big guy like me its a XL frame.can anybody help me ?I am a rookie here. here are some pics i took hope you can see what i am talking about. i put an x on the spots where the spoke is and i circled the tube puncture.

What tire pressure are you running?

Sounds like a pinch flatting issue.

put a little piece of duct tape over the spoke inlet. if it still punctures try running your tires at a higher psi.

With a pinch flat, shouldn't he have a "snakebite?"

The OP might look for another puncture nearby the first, so that the two punctures together look like a snakebite.

If the OP has a snakebite, I would recommend that at 288 lbs he inflate his rear tire to the maximum pressure printed on the side of the tire.

If the OP's tire doesn't allow more than 120 lbs per inch, he might consider a tire like the Schwalbe Ultremo that goes to 140 lbs and has very good flat resistance.

He might also consider a 25mm or 28mm tire, with the rear tire pumped to the max.

Not always. There's also the possibility of a bad bunch of tubes.

What the hell is a puncher?!!

nm. bad reading comprehension.

120 psi im running bontrager race lite hard case with triple puncture protection

im running the recommended psi of 120 psi max.

Cover suspected area of rim with thicker tape.
Run your finger along the inside of you tire to make sure there is nothing inside of it giving you flat.
Install new tube very slowly to make sure it is seating itself correctly. Read here if you are unsure https://www.parktool.com/repair/readhowto.asp?id=100
Take the velocity stickers off your rims.

thank you. you solved my problem it is the rim tape. i will go back some time this week end to my l.b.s. and get that replaced with wider rim tape. again thank you guys for your support.
