So, funds are low? Economy in the toilet? Grab a set of bolt on skewers to drop some weight off your rig. Riding around they are very secure, probably more so than quick releases. Also, unless you have a set of spare wheels in the pit, it doesnt really matter anyway----race them.
Steel shaft bolt ons are cheap. And only weigh 66 grams (about half the weight of Dura Ace skewers) pictured above.
And titanium shafted ones are around 45 grams (for twice the price).
Lastly, search the + 1 lap archives. Cheap weight tips are a plenty.

Ali sent in his Ridley which he calls "light-ish". Ali, any cross bike under 16 pounds is just plain light in my book even if it is small. Nice rig.
"I just switched my drive train to Sram Rival from Ultegra/DA mix, the bikes weight dropped to 15.82. Almost .5 of a pound, it was somewhere over 16lbs with the Shimano. 34c mud tire setup brings weight to 15.85lbs.

I made this chain tensioner awhile back. It worked great on smooth roads but not so hot on rough trails (maybe it needed a design tweak?) The reason I just didnt shorten the chain was I liked to switch cogs based on race terrain and conditions.
Took some flat aluminum, drilled some holes as shown below. Then stole a derailleurs wheel and screwed that onto the plate. The trick is to bend the plate the right amount.
