I just haven't built enough of them yet.

Tonight I almost gave myself an ulcer trying to get my back wheel built after the shop closed.

I'm using Velocity Blunt 650b rims and Shimano XT 756 disc hubs. The spoke holes on the rims are drilled right and left of center on the rim. Using Shimano's recommended lacing pattern for disc hubs, I can't for the life of me get the parallel spokes to line up with the valve hole. I just need to offset them one spoke hole to get that to line up, but if I do that, the spokes have to cross the center line of the rim and the nipples will be at an odd angle. Can anyone tell me what the **** I'm doing wrong. Feel free to blast me with the flame throwers of derision and shame. :o

side is very tight... non drive side is too loose. More or less was told that releasing all the tension on the spokes would cause the rim to go out of round..

Rim is a good quality alloy.. I am told.. and the spokes are stainless.. 36 hole rim. On an older Schwinn.. of which I have about gone thru now.

Why can't this rim be stabilized.. in some brace/bracket... and the spokes loosened.. the then retightened??

like the man who did the work.. just don't think I'll ever even let him lube my chain.. at this pt. The 'new' shop I am trying gave me the 'cant loosen'
scenario.

The noise riding is more than annoying.......... :). Did read the articles per spoking and building a wheel.. good stuff. I've been told a wheel should last thousands of
miles......... the original did.

and extended out front a little, than the stoker being on too tall of a bike. Plus the bike was foud that way. Are these considered
fairly safe? I need a good 3-4 inches of rise to put the bars where I need them, and I have a nice 115mm threadless stem that will put me about where I need to be. I want to run drop bars about level with the saddle for long distance comfort. To give you an idea of what I am up against, here is the bike in as found condition, with the saddle up front at the height I need it for correct leg extension. Maybe I should drop the cash for a technomic deluxe and call it a day?,,,,BD

Forgive the condition, it is a recent acquisition, and will get the full treatment.

I am now the proud owner of a new Lynskey frame. Got a good deal on it, partially due to some purely cosmetic paint damage. That got me thinking about stripping the paint and leaving the titanium exposed. I love the look.

I spoke with a stripping company who has done other titanium frames, but have never done a Lynskey, and had some questions about the prep work the factory before painting (i.e. frame scuffed before priming to promote adhesion, or if it was cleaned and was primed with a self etching primer). I spoke with someone at Lynskey today and they seem to consider the prep and paint process they use to be some kind of trade secret and weren't forthcoming with information.

So, my question to the forum is: has anyone done this, or had it done? What sort of results did you have? I'm leaning towards having it dunked to strip everything, I just want to be sure that I'd be able to get a nice finish on it once I go over it with a 3M pad or something similar.

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.

Could the threading inside the crankarm have gotten stripped while I was riding? Why else would the pedal be at this weird angle and only screw in like that? Maybe some WD40 will help?

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 (schrader) too on the new tube.

Only bits left are the rim or the tire, because I've checked for punctures on both tubes and found nothing. Loss of pressure persists even when its parked. Its in my apartment so no one's fiddling around with it either. It doesn't have particularly good rim tape. Also a couple of spokes protrude by about 1 or 2 screw threads (maximum). Is this protrusion enough to cause a leak? Anything else on the rim that I should look for? I've hardly done 50 miles on the bike so an aging tire is out of the equation. I have the exact same tire and tube set on the rear wheel and that hardly loses pressure.
