I broke the metal strap that is used to attach retention strap from the front bail of my Grivel Rambo 4GrivelRambo 4 's. It seems that this might have been a blessing in disguise as it made me do some comparisons of the front bails (I have few other Grivel crampons laying around (Grivel G14GrivelG14 's, my brother's old Rambo 2's).
I replaced the whole front bail with the one from mono-point set of Rambo 2. By doing this I noticed that the bail of Rambo 2 fits better with my Scarpa Phantom Guide's. It is not asymmetrical like Rambo 4 one, but this doesn't seem to matter. The difference is that the bail is narrower, thus eliminating the possibility of horizontal movement almost completely. The front bail is slightly longer though, so I ended up moving the front bail one step further back. This effectively moved the boot backwards half a step.
After noticing this, I compared the front bail of G14 and Rambo 4. Rambo 4 bail is significantly shorter, a bit narrower and asymmetrical in shape. By using slight violence I was able to fit Rambo bail on my G14. This moves the boot backwards quite a bit, which causes two changes:
- front point gets effectively longer (which is otherwise significantly shorter than on Rambo 4)
- secondary points and small additional points move significantly towards front giving them a much better possibility to actually hit the ice
I am generally not a big fan of very long front point (added leverage equals added strain for calves). However there's such a thing as too short. This new setup looks much better than the original one so I obviously need to give it a go to test whether this translates to better real-world performance.
While I was at it, I also tried out my new DremelDremel by sharpening pathetically dull secondary points.
