Bearing in mind that it's only possible to delay the determined thief, I've developed, as promised, my Mark1 Disc Lock. The aim was (1) to make a lock that would'nt damage the front mudguard if I forgot it was there. (2) To be able to carry it on the bike when not in use. (3) To use a combination lock so there was no danger of losing a key.
First, I planned to utilise this aperture between the caliper and the fork leg.
Like so:
I used a piece of tuff plastic/polythene? rod we had lying about in the workshop to make this prototype.
This stuff is very 'shear' resistant.
I planned to use this short bit of frame to carry it when not in use.
And, because I've found my auxilery charging point is more convenient on the off-side, I've incorporated it in the 'mod' and made a new bracket that needs only to make use of the one sub-frame bolt. The elongated slot fits over the bracket that holds the brake pipe in place and once located is held rigid and protects the brake pipe.
The 'bar itself fits like this....
But in practice it's easier to insert from the near-side and the lock then comes easily to hand.
And it tucks away thus..the 'hook' is shaped and slightly flexible so that it clips onto the fram tube and holds itself in place. With the lock in place it's held tightly.
Added a better (albeit a key type) lock.
The only 'downside' is that I may need to move the bike slightly for the wheel to line up with the aperture in the disc mounting. There's a mark 2 (in aluminium?) in the pipeline along with a more substantial combi-lock.
Not everything we turn out is so small tho...
It's been a long winter and yes, I know; I need to get out more.
