PACK Replacement Mountain Cruiser Bicycle Review

It's so hard to find a camera with a long shaft. My local bike shops didn't have it. Luckily this seller made it and it fit perfectly. Thanks for saving the day!

I just completed a 2500 mile bike ride for two months. I have never inflated the front tire of my bike that had one of those inner tubes! I have been on tours like this for over 20 years and this is the only time it has ever happened.

My grandson is back on the road after the tube on his new 29" Genesis GS29 mountain bike failed after 4 weeks. Bought from Revain. Fit perfectly and got it back on the track and the camera seems to be of much better quality than the original camera sold with the bike (no wonder).

None of the hoses lasted very long. After a few rides, the valve stem base has split and cannot be repaired. It was a waste of money and a product I do not recommend at all. UPDATE (8/31): The company refunded the money so I increased the star rating from 1 to 2.

Not quite as advertised. For mountain bikes you need a full 48mm valve stem to attach the pump to the stem. I have ordered a pair. They came without a box and the stem was about 1 inch long. It didn't protrude far enough out of the rim to engage the pump. Definitely not 48mm. I'm ordering again to see if I get the right thing this time. I want to get a tube in a box. Maybe this makes for the right take away.

has a longer than usual strong metal valve stem. Since my rims are about 1" deep this tube should be useful for any deeper rim (although I don't know about MT Bike Aero rims and don't need them!) Otherwise pretty much the same as the other tubes. Pumps and inflators can cause different stresses on valve stems, this overkill seems to make the brand a good choice (I've blown stems on road bikes before, hence 5 stars for beef).

These inner tubes are no good. I've been running the same Bontrager tubes on my MTB for years. When I changed my tires a few days ago, I decided to change inner tubes as well. The first thing that struck me was that these guys were smaller in diameter and thinner rubber. My old Bontrager tubes were designed for smaller tires and were bigger and thicker than them. My second ride on a very well known circuit ended with a puncture! Did I mention that in the 6 years I've owned this MTB I've never…

I have never had a tube rupture and have been cycling for over 40 years. I installed this on my mountain bike a few weeks ago and when I took it off for my first ride with a new tube I added some air (the tire is marked 30-50 psi). I think it was about 32 pounds per square inch when it exploded. I thought it was a strange phenomenon. I replaced it with the second tube from that order and halfway down I ran over a rock and as soon as my front wheel hit the rock the tube popped out of the tire…
