SR Tubular one peice crank

[billycrabtreeomer]

Whilst looking though my collection of O,S part i discovered two sets of hollow one peice cranks. Weighing some wot lighter than my 401 flight cranks
im thinking of using them . Has anyone got any feedback on these cranks as i havent seen or haerd nout about them .
weight 665g , lenght 175mm

You will probably find your 401s will last a bit longer than a hollow opc. Solid ones are bad enough!

I've been using a Tioga Max-Flo tubular crank which is identical to your Sr.
I've given it quite a beating, and haven't had any issues with it at all.
Obviously it'll never last as long as a set of 401's, but it does weigh less than the flights, and how much abuse are you going to be giving it...

Yes i agree 401's will last longer & make my restro project a better bike to look at & most of all too ride at my local track & skate park.
Never heard of tioga hollows but know they make quality parts . Intened to race & jump on these cranks like a 39 year old should SLOWLY HA HA ,
