I need to upgrade my MTB, but I'm not sure how my R5000 would be best spent - any help would be much appreciated! I have an old Schwinn Mesa that I bought off my brother-in-law for R 2,500 some years ago. The front fork is forked!! So that needs replacing. The front wheel is very slightly buckled - so that also needs to be replaced. 1. What kind of front fork should I get? Are forks brake specific? 2. Do I replace both wheels? Are rims brake specific? 3. If I get disc brake rims, I guess I need disc brakes too then? 4. Is everything pretty simple to install oneself or should I look up a bike shop? 5. Any bike shop recommendations (JHB North) that will fit components for me? Currently looking at: New - Hygia Elite Carbon disc brakes (R1800) 2nd hand - Rock Shox Sid dual air (R1000) 2nd hand - Alex DP17 Rims on Novatek Hubs with Tires (R1300) Thanks hubbers!!
