Miche Primato Pista bits

Hi all,

Many thanks for the good advice. I do indeed have a couple of freewheel
hubs that I could have simply redished and bunged a track cog on, but I
figured that I would avoid risking my luck and get some proper track hubs.
Sheldon recommended the Suzue ones (how could I resist with a name like
that) so I've gone with their cup-n-cone ones, which look suitably shiny.

Also, as people have recommended, I'll stick with my road cranks for now and
simply fit shorty chain bolts, so I can run just one chain ring.

I can't wait! I rode to work and back today in a 49/19 - 68" (on my lotsa
gears bike) and found the hills were doable. There's a short steep bit
(perhaps 5% for 500m) on the way home that pretty much dictates the upper
limit. I reckon a few weeks of having my legs spun off like this will do
wonders.

Regards,

Suzy

be aware that the "real" track stuff doesn't have good seals on the
bearings. don't know if you plan on playing in the rain but it's a
great time to practice your skip-braking.

Next down the
list seems to be the Miche Primato bits, which seem at first glance to
strike a good compromise between shinyness and expense. Are they as nice as
they look? I see they use cartridge bearings. What do I do when said
bearings disintegrate?

Miche use 6001 series bearings in both their front and rear track
hubs. It's one of the most common sizes found in bicycle hubs fitted
with sealed bearings. Their bottom bracket bearings aren't
serviceable, but they're cheap enough to regard as disposable.

The next issue is that the cranks are 135mm PCD, whereas most other track
cranks seem to be 144. Is this likely to cause grief?

If (when) you start track racing, using 135 mm. p.c.d. cranks will
force you to be somewhat more self-reliant to own all the gearing
options you'll need for the range of events you ride. There will be
fewer people from whom you can borrow a chainring than if you were
using 144 pattern cranks. On the other hand, there may be fewer riders
hassling you to borrow _your_ stuff.

For fixed-gear road use, the bolt pattern will mostly be a non-issue.
There are fewer manufacturers supporting the 135 standard, but you'll
find 3 mm (1/8") 'rings from 46 to 52 from Miche and an even wider
range of 2 mm (3/32") 'rings from T.A. and Campagnolo.

Finally, is it an issue squeezing the back end of a 126mm wide bike down to
120mm? It's had 130mm wide wheels forced into it before without significant
complaint.

Most steel road frames like the one you mention should tolerate this
kind of compression. However, it's such a trifle to stick a 3 mm
spacer on each side of a Miche rear track hub to bring it to 126
over-locknuts that it'd be an error to omit this simple remedy.

oh yeah, i have a pair of Miche - the freakin' axles are a wee
short, the nuts have a few exposed threads. not the end of the world
but don't know if i would exacerbate the issue with 6-mm of spacers.

I can't readliy explain the configuration of your hub. My "hands-on"
experience selling Miche's track hubs goes back only a year and a
little. In that time however, the hubs I've received have invariably
been fitted with rear axles that could only be described as generously
long (170 mm., plus or minus a smidgeon). The Miche rear axles have
been at least 5 mm longer than those fitted to current Dura-Ace track
hubs. Axles in Campagnolo's rear track hubs measure shorter still
(less than 160 mm.).

These current Miche track rears should be plenty long enough to span
126 mm OLN.
