650b Conversion!

Posted by Susan on June 1, 2011

Liz loved her Casati, but felt limited by the high pressure skinny tires. This light and fast Italian racing bike made a good candidate for a 650b conversion.

The 650b Conversion allows her to ride with a larger tire, which means she can now ride our favorite dirt paths.

650b allows for more tire clearance on the casati

32c Gran Bois 'Cypress' tires fit the frame, with room for fenders, if desired

Before the conversion Liz’s saddle was too low to permit clearance for a Carradice Saddle bag. But now, there’s plenty of room!

Now the Carradice won't drag against the tire.

Also, there is no more toe overlap!

Liz enjoys riding this bike more than ever. With the fatter tires, it is more comfortable over Boston’s rough roads and able to conquer many a dirt path. She can’t wait to ride it at D2R2!

Some notes about the Casati set up

It sports a compact double crankset. Again, I converted a triple to a double using a chainguard for the outer ring. Due to oversized oval tubing (Columbus Oversized EL tubing ) The Casati cannot take a clamp-on derailleur.  This presents a problem, as the derailleur braze on is located too high for use with a compact crankset. The problem is solved using a triple derailleur with a chainguard. Right now, gearing is 44, 32.

Another triple converted to a double.

Here’s my new custom built Sketchy, built by expert frame builder Mike Salvatore of Seven Cycles. Made to fit me and my riding style, it’s light and fast, has plenty of room for fat tires (700 x 35) with fenders, fits a rack on the back, and has triple water bottle mounts.

I wanted a simple mounting solution for rack and fenders.

Since this bike is intended for epic rides (such as D2R2), I wanted a third set of water bottle cage mounts. These also work nicely for holding my Lezyne pump. Though the frame does also have a pump peg, should I decide to carry a “normal” size road pump.

Pump intalled in place of third water bottle.

One good use for a third set of water bottle mounts.

Since I don’t race, I don’t ever find that I need a front ring larger than 42. This triple crankset is converted into a double, with a chain guard in place of the third chainring. This is a simple solution to compatibility issues of using small rings with standard derailleurs. This gearing is enough for me, the chain guard offers a little extra protection against grease when I’m commuting, the weight is negligible, and there is less chainrub in the front.

I’ve put about 1,000 miles on it so far. It’s wonderful to ride.
