Hi there.
A while back I came into a brand new CCM Presto Road Bike from
Canadian Tire. This is the bike I posted an image of for someone who
was wondering what unwrapped aero brake cables would look like.
Here are some of the thoughts and modifications I made to that bike.
Both wheels came complete with brass filings in them and under the rim
tape. One filing punctured the rear wheel before I discovered them.
The front rim had a rattling sound in it when I took the tire off to
check for filings in it. The rattling was caused by the plug stamped
out of the rim when the valve hole was made. It was between the rim
walls and was not easy to get out.
This bike has drop handlebars attached to a 90 degree aluminium stem.
The bars are steel and are the same diameter as mtb bars so that the 7
speed Revo twist grip shifters will fit on the straight section at the
top of the bar. These shifters are able to fit there because the bars
are in two pieces and one side fits inside the other. there is a long
thick two-piece shim that holds the bars to the stem. To prevent the
bars and/or the stem from moving whilst adjusting the location or
angle of the bars there is a hole drilled through the bars and a
larger hole in the shim pieces so that they can be bolted together. I
think these bars are an accident waiting to happen so I ditched them.
It was the wheels i was really interested in and i have put them on my
1980's Tange #5 tubing Miele Sport Touring bike. I used Campagnolo
2001 9 speed Ergo levers to shift the Shimano derailleurs over the 7
speed freewheel. This works wonderfully with very crisp shifting. I
have a triple racing crank with 50 - 40 - 30 chainrings.
The crankset on the CCM Presto was way too far out to the right with
the factory bottom bracket. I gave the frame to a friend of mine and
we built it up with other extra parts I had on hand. We bought a
Shimano Cartridge bottom bracket for it and had the shop install it
because the right hand cup was far too tight for my tool to loosen it.
The shop used a six feet long pipe over their tool to get it off. I
jad to use an 18 inches long steel pipe over my 17 mm wrench in order
to break loose the 17 mm lock nut on the rear wheel in order to loosen
the cones a bit as they were too tight.
The CCM Presto ftrame has been built up with Alex D22 rims on Shimano
hubs with an 8 speed cassete cluster shifting with an 8 speed Ultegra
bar end shifter set. The stem is shimmed to accept a 26 mm aluminium
handlebar and the original brakes are still on the frame but with old
Shimao Exage brake levers as my buddy liked the contour of them better
than the wider bodied levers that came with the bike. The bike rides
very nicely now and my buddy is thrilled with it.
IF anyone buys a CCM Presto road bike they better be prepared to a)
have it checked over by a competent bike shop and be change out the
handle bars and shifters to aluminium bars and bar end shifters if
they do not want to risk the steel bars breaking at either the centre
joint or the hole in the right hand side where the shim is. Regular
price of this bike is $299.00 Canadian and I think it is far too much
to pay for a bike that is going to need as much work as this one did.
