Montessa titanium spindle set
I’ve just finished a titanium spindle set for Montessa trials bikes. The set comprises front and rear wheel spindles and swinging arm spindle including rear wheel and s/arm nuts, the front spindle screws straight into the fork leg so there is no nut for that one.
Unfortunately in my rush to get it to the post office the photo’s i took of the set didn’t come out, so we’ll have to make do with the close ups of the heads!
I’ve modified them from original slightly, the OEM wheel spindles were solid alloy, so i’ve drilled these titanium ones. The swinging arm shaft was steel and already drilled, but as its titanium i drill mine with a bigger hole and put finer threads on the end.
Weight wise my titanium front spindle is 147g, OEM 190g. Rear spindle 147g OEM 148g and swinging arm 113g OEM 224. The biggest weight saving is in the s/arm where we’re replacing the steel one with titanium, and shoving a bigger hole up it and making the head smaller and neater, the front spindle is not bad considering the OEM is alloy and to say that there wasn’t all that much i could do to modify the rear spindle at 1g less than the OEM alloy one i’m pleased with that.
