Ive been searching for a while for fork deals and have come to the conclusion that it's not the right time of year for the amazing deals. But I guess that depends what specs your looking for. If your fine with a straight steerer and 9mm drop outs, there are deals out there. But when you start looking for tapered with 15thru axle, it's slim pickings.
I've talked to guys who have found close outs on jenson for Sid 100mm tapered 15thru for 400 bucks....where are those deals!!!
I think you should keep your eyes open on eBay. The good deals sell out immediately. Check the completed listings for actual selling costs. Otherwise you have to be patient and jump on the deals. On ebay, click on the option for newly listed. You might get lucky and find one that has been listed for less then an hour. Or email the seller and ask if they can do a better price outside of eBay. I've convinced a lot of sellers to drop the prices significantly...but I've also had guys with unrealistic price expectations.
The rockshox Reba seem to be the best deals now. Most are adjustable from 80-100-120 with spacers regardless what it's listed as.
This should be easy..9mm QR, 100mm. Just go on Ebay and type whatever mid-tier fork name and something will come up new or virtually new like a Reba or Manitou Minute. Personally I used the Minute Pro. It's a fantastic fork for the money if you can find one from 1-2 years ago.
