9 or 10 speed cassette help

alexander flint

Just got a boardman comp racing bike 2010 and have noticed that on the chain ring it says ten speed. Yet when i looked at the cassette it only has 9 sprokets. Is this normal and does it mean that I can add a sproket.

Im new to all this and am some what confused.

Thanks

Most modern chainsets are 9/10 speed. This is normal.
You cannot add another rear sprocket without great expense (new shifter and cassette).

Thanks for that Chris, would I not be able just to add one extra sproket.

Like I said im knew to all this

no as Chris said your current shifter will only shift for a 9 speed cassette so you'd need a 10 speed shifter and a new cassette, you can't just add a cog afaik!

alexander flint

just to clarify then why does it say ten speed on the chain ring

gaddster

is it this bike here? http://www.bikeradar.com/gear/category/bikes/road/product/review-boardman-comp-08-22946/

alexander flint

I think so
the only difference i think is that my bike is 2010 not 2008

gaddster

yea noticed that after I'd posted it, sorry. Did you buy the bike new?

alexander flint

yes

gaddster

Then that's how it is. The 2011 is 10 speed I believe but not the 2010, says 18 speed wherever I've seen.

it'll say 10 speed on the chainring as it will compatible with a 10 speed cassette if it had one fitted.

Well for a 9 or 10 speed the action of shifting the front ring wont be any different.. so maybe you just have a component branded for 10spd (more expensive?) but only used for 9 speed.

Wouldnt worry about it too much
