På Veloform sprutar han in fett i vajerhöljena innan han leder in vajern. Det ska motverka att det kommer in fukt som fryser.
Har det redan frusit ska man kunna lösa det med låssprej/5-56/WD-40.
http://www.bakfiets-en-meer.nl/2009/12/20/frozen-cable-time/ So here's what you do to fix (or prevent) a frozen cable: 1. Let it thaw.
2. Remove the crimped end cap and make sure the end of the cable isn't unwound or damaged. If it is either rewind, shorten or replace the cable as necessary.
3. Remove any kinks in the cable so that it can easily be pulled and reinserted through the housing.
4. Pull the cable out.
5. Seal the nozzle of a compressed air pistol against the upper end of the housing and blow everything possible out of the housing. (alltså med en cykelpump då eller?
6. Seal the dispenser straw of a suitable light oil against the brake lever end of the housing. It might be necessary to pull the housing cap to do this. We use a generic multipurpose oil with teflon but just about any light oil should work fine. Don't use "dry" type lubricant because it won't displace the water for long.
7. Spray the oil into the housing until it begins coming out the other end.
5.5 Oops. Put a rag at the brake end of the housing to catch the oil coming out at great velocity.
8-9-10. Thread the cable back into the housing, readjust the brake and crimp a new end on.
