This is a rhetorical question. The answer is obviously, "YES". However, this is not the case when you switch from 27" wheels to 700c wheels and forget to adjust your brake pads....like I did....and have your pads wear through the sidewall in 1/2 hr. I feel like an idiot, but at least I noticed...

So, I just noticed that my LEFT pedal is going into the crank arm at sort of a weird angle. I don't recall it being that way before. After removing it with a wrench, and trying for close to 1 hour to ease it in straight, I'm close to giving up. It only goes in at that same weird angle. ...

I have a set of Shimano 600 brake levers I am giving to a friend. Her hands are quite small and unfortunately there is no reach adjuster screw on these levers. I seem to remember some...wedges that can be used to hold the lever in a slightly closed position. For the life of me I cannot seem to...

I have a Formula rear track hub that I respaced to about 135mm (from the usual 120mm) to fit a singlespeed cyclocross frame. I then installed an ACS bmx freewheel. Now I'd like to take the freewheel off, but my Park FR-6 removal tool can't fit over the outer locknut (my spacers are between the...

Hello everyone, I have a cheap bike with 27 x 1 1/4 tires. My front tire had been giving me issues for some time, I'd pump it to about 90 psi (it can take upto 105) and it'd be flat in a couple of hours. Got a new tube and well, rideable pressure lasts for a day max. Changed the valve set...

I had a single speed on my mtb but found it to be too hard on my knees so i redid the wheel on a Deore hub with an XTR 9spd cassette, XT 9 speed rear mech and SRAM 9 spd chain.when i was setting it up they worked perfectly and changed gear perfectly smooth but when i put pressure on the pedals the...

bought a new saddle and I'm not sure where exactly to position it on my seat-post. another thing is that how high should I keep my seat-post for optimal performance. last thing is that I want to buy a suspension seat-post,what will be the best option under 30$ , any suggestion on how to measure...

Hello everyone my bicycle's shifter recently broke The shifter has the brake lever integrated and is a 7 speed The name on the shifter is Shimano STX RC and the model number is ST-MC33, this is an old model and my bike is also old but in really good shape, i am trying to get this part however it...

I have a rim I've taken twice to the LBS to get trued. All manner of wobble and my brakes would surge when braking at faster speeds, especially downhill. In the end I bought a new rim and just set this one to the side, and as expected my problems went away. I just bought a Park Tool Truing...

Does SRAM use standard bake and shift cables or do I( need something special for SRAM deraillers and brakes?

I am currently trying to find a cassette and chainset to suit my new build. My current bike uses an 11-28t cassette with a 34-50t compact chainset. I find that the lowest gear this provides isn't really low enough for some hills and I find myself having to mash a bit. How much difference would...

I haven't worked on threadless headsets that much and just put on a new stem with a threadless setup. I snugged the compression bolt/cap. I then tightened up the two bolts on the stem itself, securing it to the fork. This is a Campagnolo Chorus headset & a Thomson stem. My question: when I...

My old floor pump just crapped out and I never liked it much anyway, so I am looking for a new one. My tires range from 700c Balloons to 20' high pressure. So I want something that can fill the balloons reasonably fast but still handle the high pressure tires. Suggestions?

So I've just received one of these racks in the mail, and am unashamed to say I can't work out how exactly to mount it... and the old man mountain instructions are, well, less than instructive. Anyone have experience putting one of these on? particularly on a road bike without brake bosses? Even...

My Giant Iguana has Hayes HMX-1 mechanical disk brakes, I just replaced the pads for the first time. Of course, the fresh pads are significantly thicker than the old ones and when I install the front wheel, the rotor sits right up against the inside (stationary) pad. The inside pad adjustment dial...
