24/28 will do lar... unless you weigh 300 pounds

in fact a stranger 20/28 configuration would also work as the front wheel don't take up that much of a hit...

just build the rear in 3 cross lacing patern and that should hold up...

of course... why would you want to cross the front unless you are heading for CX races...

just find a wide enough hub... 70mm and above and the wide stance bracing angles should give the wheel plenty of stiffness...

what is proprietary anyways??? radial is already quite against the rules of wheelbuilding and there is no 2:1 or G3 lacing pattern for front wheels...unless you are speaking of twist and solder techniques which i think is crazy waste of effort...

custom wheels don't have much proprietary rims lar... nipples also the same... most you can get is aluminum nipples which is slightly lighter, but those are still replaceable items...

there are options for straight pull hubs nowadays... spokes are hard to come by in the first place because of the length variations... especially with bladed spokes as you can't cut and re-thread them...the ones who have them usually have the hubs and rims as well so they can pre-determine the length of the spokes they need to stock in every possible configurations...

the only thing that will kaput eventually is the rim as that is a non-repairable thing once the brake track wear line disappears and you start getting a concave shape on your brake track...wheel bearings and freehub body are replaceable if you can find it... spokes and nipples are also replaceable if you kept spares...

all my previous sets of wheels expired eventually due to exhausted brake tracks...and if you can't find rims with the same ERD, then it is no issues as you can rebuild the wheel...

if i want to setup a home workshop, do i need to have a tensiometer to check the spoke tension during wheel truing?

of course... spoke tension is very critical... if you have an overly loose spoke.. the elbow or spoke head will break due to fatigue from all the pulling and releasing and with elbow freeplay in the spoke hole..if spokes are tensioned too much, either the aluminum nipples will crack or the spoke will break...

aside from a good truiing stand... the armory for a very good wheelbuilder includes a complete set of very good nipple wrenches, tension meter and it'll be a plus if you can afford to get spoke length rullers, cutters or a Kowa/Morizumi spoke cutting machine (thinking way over my head)

it is also good to have spoke prep ready like wheelsmiths spoke prep so your spokes threads in easily with the lubrication and seizes enough not to loosen itself after finishing the wheelbuild...

nipple and spoke washers are a plus as well.. nipple washers to reinforce rims without eyelets like carbon rims or kinlin niobiums and spoke washers to minimize the spoke freeplay in the spoke hole... with that also requires a spoke head puncher... DT has em...

some syiok sendili vids...


wheelbuilding with lubricated threads, 1 of a 3 part series...

just for periodical truing, not wheelbuilding. should have tensiometer too?

if your squeezes can tell you accurately how much each spoke is tensioned... then you can make do without one...

else, you are bound to run into over-tensioning or over-loosening spokes over time... after every few trues... it is good to unwind all the spokes and re-start from light tension again to get the wheel track straight, i think personally...

uniform spoke tension is good for overall wheel health...

one of my fav articles of zinn interviewing rich sawiris of wheelbuilder.com
Rich Sawiris-Wheelbuilder.com

didn't actually exposed how they build their wheels... but it did mention their directions on wheelbuilding... same goes for after build wheel truiiing...

it's a cheap version to the park tool TS8 i believe... it should do well enough... but, don't you think it's overkill to get a stand?

i just flip my bike, clamp up my calipers as close as i can get to the rims and adjust from there... i don't chase hops as they usually aren't too bad... if hops is an issue, it's time for the bike shops to put my money to work...

TS2.2 would be more preferable and if you are a gadget junkie... get the dial gauge set as well rclxms.gif

"A notable update on the powerful Edge 800 but not quite what we were hoping for"

LiveTrack followers can track your progress almost in real time

This should be a boon for solo riders who would like to reassure loved ones they're safe, or even racers who want to transmit their progress to fans during an event. It's not thrilling to watch if you're on the other end ("This is about as much fun as watching paint dry," said BikeRadar technical writer Josh Patterson) but it's useful information nonetheless.

ok la, not too expensive. so i can practice, and maybe one day will build a set of wheels on my own. hopefully

wanted TS2.2 initially, but when i saw the price. woahhh..

you are not... it's just 2 days old...

the review is right... it is nothing earth shattering with the new features from my perspective... they just made it even more gimmickry and most probably a battery that flats faster than you can bonk...

unless you got some CNY bonus money to blow anywhere you like after even spending it on a 12-prosty orgy night... then, it's really up to if this screen touching, nothing fancier, GPS tracking, anti-terrorist missile guiding computer fancies you... hell, they'll throw in some facebook or twitter check-in features integration sometime in the future...

imagine how you want to explain to your other half if you just so co-incidentally unluckily suffers a double puncture in front of a row of brothels with the chain lodge jammed up in the derailleur and got captured by the GPS???

it should come to over RM1k if you choose to get the dial gauge...that is why i said it's overkill... even TS8 price which is targeted at home users is a pinch to the nuts for something you don't use often...

in ebay, i think you can find for less than that...not adding shipment charges which is a bomb due to the weight...
