    Hello all,

    Nice to join you, apologies if this has been covered at length before (please post links). I am male weight around 17 stones 110 Kg and recently got a “Hybrid” bike. The hybrid is heavy and I’d like to be faster, so I am looking at spending around 1000 quid on a road bike, things like the Scott Speedster 20, these are available as doubles or triples.

    My current bike weighs about 15Kg and has 28 38 48 crankset with a 14-28 cassette, so I get a 1:1 ratio as the easiest, I can’t obviously try all sorts of bikes up all sorts of hills, so I wondered if any of you had moved from a 28 to 28 ratio to a 34 to 30 etc. ratio on a significantly lighter bike and if you were able to get up hills in higher gears than you could before?

    I hope you understand my question and any assistance would be greatly appreciated!

    Thanks for your time!

    Chris

    I had been looking at
    I had been looking at Specialized Secteur or Roubaix triples before seeing the Scott today, would they be less “severe” starter road bikes? Do you think?

    Thanks

    Thanks for the replies, I
    Thanks for the replies, I will try a few more bikes before buying, I had never sat on a dropped bar bike before sitting on the Scott today, it felt not bad, but with no pedals etc I couldn’t really say how it would be in the long term.

    In my mind the mathematics makes sense, I just kind of asked myself ” if I added 6 kg to a backpack on my bike how much harder would going up hill be?”

    How can you try before you buy, as the bikes in the shops don’t have pedals on them?

    Thanks again!

    I started on a scott
    I started on a scott speedster bought second hand with a tripple I still use it today for commuting but it really is uncomfortable even on short rides it honestly beats the crap out of you.
    I started riding when i was about 90kg and am now down to 84kg (i’m 35). The front end is pretty low and the saddle that came with it was terrible I’ve just bought a new saddle (same as on my other bike) to see if this will improve it. The scott made me decide what i didn’t want in a bike. I then bought a Felt Z series (many other manufacturers have similar geometry of varying price) over the more racy F series straight away i could spend far more time in the saddle and be much faster i’ve done 2500 miles on it in less than a year my average speed over my local test route has improved by 2mph. So to conclude try before you buy!

    To answer you question about gears personally i don’t see any advantages of a triple. My felt came with a compact and 11-30 rear cassette you can get up anything with that. Today I run a 11-25 but it’s pretty flat where i live I only change it when i have a really hilly sportive takes less than 5 minutes to do.

    Mathematically, the gear
    Mathematically, the gear ratio makes a bigger difference than the weight.

    Total weight goes from 125kg to 120kg, or 4% lighter.
    Low gear goes from 28/28 to 34/30, or 13% harder.

    So, if you regularly use that 28/28 gear, yes you will sweat a little on 34/30. But if you keep riding you should both lose weight and get stronger legs…
