Superlight Club Racer with Stainless

April 2nd, 2014

Well this has been a fun one. We have a complicated relationship with stainless steel: we’ve always loved it for things like dropouts, where the paint is sure to get chipped anyway; and we love the all weather durability. But it’s expensive, and even from three suppliers there are a limited number of tube profiles available. Part of the benefit of a custom frame is that we have so many options to choose from in order to optimize performance and comfort.

So, for Myles’ club racer, we decided to use a mix of True Temper S3 and OX Platinum tubing, along with a KVA Stainless drive-side chainstay; and then we upped the ante by doing all the interfaces in stainless: rear dropouts, cable stops, H20 bosses, and brake bridge. A true all-weather steel bike, where it matters.

The frame comes in a tic over 3 lbs, and with some very nice components indeed (King/Enve wheels; Enve fork, cockpit, and seatpost; and Sram Red/Black group) the complete bikes is a svelte 15.75 lbs. Not bad for a durable and repairable heirloom!

I used the Enve 1.0 fork with a 50mm rake and a 72.5 HT angle – this setup is eerily comfortable over rough roads while still being whip-quick, and gives a little longer front center for a stable wheelbase with short chainstays – 41 cm with a 73.5 ST angle and 25c tires. ST center to center is 52.5 cm and effective TT length is 55, with a 10 degree slope.

But enough talk – first more pics of the complete bike, then some shots of the frame before building up.

Jay also painted a 1895 Rudge Penny Farthing:

And I modified a Surly Ogre to accept belt drive with an 8 speed Alfine hub – they said it couldn’t be done, but after a little chainstay crimping and some fine tuning of the chain, er, belt-line, it’s an all-weather commuting monster:

And finally I repainted a very rusty old Serotta in the trademark fade:
