The gears make a clacking noise. It like the chain is knocking against something. Do you know how I can fix this?
The sound normally is the derailleur arm touching the chain after shifting, and the derailleur need be shift further or less to move out of way of chain. So, When you hear the sound you may want to twist the shifter a bit, so that the sound will go away.
You want find whether it occurrs in front or rear derailleur. If it is from front, you need twist left shifter, if it is rear, you need twist the right derailleur.
If the sound persists, even you make the twist. You may need adjust the front or rear derailleur. Our FAQs has two videos which teach people making the adjustment. Please scroll down of this web page and see the two videos.
For a SP26S bike, can you turn and pedaling?
The clearance is six inches from pedal to front tire, If a person correctly pedal, there will be no issue. But if a person pedal with his heels, then his feet may touch the front wheel when turning. The following is a link to a web page teach people how to pedal, people's shoe only extend one to two inches beyond front of a pedal. How to Pedal
If you found out the pedal to front tire clearance is smaller than six inches. You may have installed the wheel backwards. Simply, remove the handlebar stem from head tube(quick release), turn the wheel 90 degrees, so the front brake assembly is in front of the fork, not behind the fork. Then put the handlebar stem back to head tube.
Check List before Riding
1. Check your brakes. Make sure the brake pads for both wheels are not touching the rims of the wheels (when brakes are not being applied). If a brake pad is touching the wheel's rim, the brakes may need to be adjusted or the wheels may need to be trued. Check out the videos on our FAQ page.
2. Check the tire pressure with a tire gauge. The maximum tire pressure is displayed on the tire's sidewall. Make sure your tire pressure is at least 85% of the maximum marked pressure.
3. Check the quick release mechanisms. Make sure the handlebar quick-release, frame quick-release and seat post quick-release mechanisms are locked. Observe and follow the minimum insertion mark on the seat post and handlebar stem to avoid issues.
4. A mistake that needs to be avoided: Make sure the brake assembly is in front of the bike's front forks. Sometimes, if the user was not paying attention, the brake assembly may have been left behind the front forks. If this situation happens, simply unlock the handlebar quick-release, then turn the wheel 180 degrees around the center line of the head tube. Now, the brake assembly will be situated in front of the front forks. Then, lock the handlebar quick-release.
