I can tell you if you post what year it is and what fork it uses. Generally speaking it would fit 26" Stump jumper with quick release fork. If you happened to have 15mm TA fork, then it will not fit.
Both are QR. Front bearings are 15mm ID and with spacers (such as ZTR conversion kit) can take 15mm TA, although solution is not perfectly clean, since spacers do not held by the hub on its own.
