I have a 2000 Specialized Expedition Sport I'd like to try and semi-convert into a beginner triathlon bike. About how much would I be looking to spend to get more appropriate rims/tires? Is there anything else I should look at having done? I don't want to spend a lot of money but would like to have a plan.
Jeff,
Great question, this is one we get a lot. I would look at replacing just the tires, keep the same rims/wheels and just fit the narrowest tire on the rim you can. This would most likely be a 700x28 or 700x32. This will give you some more speed, reduce your effort and help the bike roll faster. Additionally from what i remember that model comes with a suspension seat post, i would swap that out for a rigid post , this will help you pedal more efficiently and generate more power. Other options would be clip less pedals to help increase efficiency, and perhaps stop by a local shop and have the bike re-adjusted fitwise to accommodate this new goal. Having your position tweaked to cater a little more towards faster riding could help you waste less energy.
Tires would run about $42 a piece for a good flat proof tire, plus install $13 a piece, you will also have to replace the inner tubes to accommodate the smaller tire, they are $7.99 a piece. A new seat post is about $45. Pedals range in price and you may need shoes to work with them. A fit is something that may be quick and cost very little or could cost upwards of $125.
If you really love triathlons after doing one or a few, take a road bike for a spin, i guarantee you will see the difference right away.
Hope that helps and thanks for the question
