Bianchi Sempre Ultegra vs Infinito 105

hi , i need to decided between the bianchi sempre ultegra and the bianchi infinito 105. Wondering if anyone has a view?

Infinito is from their coast to coast range which means it is more comfy. What I don't know is how much racing speed/agility is sacrificed for this.

Sempre is from their born for performance range and is aimed to be agile and fast. What I don't know is how much comfort is sacrificed image

I am new to road bikes so any help would be appreciated. I know the ultegra groupo is better than 105 by the way but I am more concerned about the framesets here.

Thanks,

Tortoise

  • Ride both. Get the best frame you can that fits well.

  • I am likely to be in a position where I have to ride the Infinito and decide then whether I want it before trying the sempre.
  • 105 is a decent enough groupset imo,  not sure how much the step up to ultegra  worth.

  • The question is about the frames.
  • From reviewing the specs for both 'versions' of this bike, I'm still not sure what the difference is, apart from one has a slightly more expensive group set and what appears to be a slightly better quality carbon in the frame - but the difference is minute. The geometry is the same.

    To be honest, if the bike fits, chose the colour your prefer, as that appears to be the biggest difference image

  • i was going to ak what are the colour choices likeimage

  • image none of then are Guiness coloured I'm afraid Seren my dear image

  • They have different geometries. I think the infinito is supposed to be more of a sportive bike with a longer heat tube and slacker angles. The sempre is more of an aggressive racer bike.
  • Also the infinito has Kevlar bits in the chain stays to damp vibrations. This means the sempre gets the power down more directly but is probably a bit more bumpy. My heart is saying get the ninja racing sempre but my head is saying my arse will thank me for getting the infinito.
  • What are you going to be using it or ?
  • Really - coz the Bainchi website seems to give the same geometries - but then again there are lots of numbers floating around and I may have had the odd glass of wine to celebrate Sir Chirs and the team's victory and I get confused easily!!

    But to be honest, I doubt you will notice the differnce - I know I wouldn't - your riding style will be a bigger influence, so go with the one that feels more comfortable!

  • Rafiki for someone with lots of wine in them you are making a lot of sense image
  • Dave I won't be doing crits but that could change I guess. Unlikely though. Mostly it will be for training for the ironman, riding the ironman, and I plan to join a club to go on rides with. Possibly for shorter triathlons too but definitely plan to do some century rides.
  • go with cheaper one and use money to upgrade wheels

  • They cost the same price. Sempre has better groupo but infinito is slightly more expensive hence with cheaper groupo they end up costing the same.

    I may quote this numerous times in the future image...... now where's that dam cock screw gone??

  • A lower head tube will give you a lower aero position so +1 for the Sempre. For the IM and C100 rides you will want something 'comfortable'. This does not necessarily exclude the Sempre as comfortable is a many faceted thing at 90 miles, regardless of bike. It is about fit - especially if you want to run 26.2 miles afterwards without being dicked for the mincing prize*

    I've looked at the geo too - other than the length of the headtube there really isn't much in it.

    Sempre it is then! Do they come with men's chainsets, or just compacts image

    *Even though gladys would win anyhow.

    image Each to their own...

  • Hahaha I plan to keep compact. Will help me ride up zig zag road image
  • +2 for Sempre based on the last couple of posts... no brainer for me now

    Still not recovered from being minced at Ballbuster eh?! image

    Bitterness is a horrible thing! image

    FWIW I would choose comfort over aggressive riding position, unless you are looking to go sub 6 hour biking. The sportive-ish bikes are desied for long rides in relative comfort. 

  • Go fast! Then you have to sit on it less. image

  • I just looked at the prices of these bikes.

    Then I looked at one of your past posts where you speak of running a 10k this July. You thought you may be able to run it at 10 min/mi pace.

    Its not about the bike.

    Save your money get a cheaper bike and train more.

    Times mean more than kit.

  • Ive been riding longer than I've been running - but on a mtb. I learned its better to buy right in the first place. I managed to run that 10k in 58:42 in the end btw - was rather pleased. You are right - time means more than kit. Might as well spend that time on sexy kit though image Price wise I'm getting a massive discount. I can get either bike for ??1560.



    I read that a south African dude road the infinito in the 2009 giro and got some good stage places. I guess while it has some more comfort than the sempre it must still be a serious racing bike. Similarly I have found people who have ridden century rides on the sempre. This is going to come down to looks image Got to love bike porn.
  • Zig Zag road is only 6%, even I wouldn't need a compact for that. Gasbag makes sense on the wheels. 6-to 8 hours on a bike is no joke. 6-8 hours on a bit of leather stuffed up NQB/NQA is fecking painful. Listen to Gladys on the comfort thing. It won't ever feel like a full suss MTB but if it's comfy after 40 miles, that's not bad. I can vouch for a Kevlar/Carbon combination as the closest bikes get to Bentley comfort, but then I am a Cyfac tart.

  • I just mentioned zig zag because of the Olympics image I want to ride around the Surrey Hills. Anyway these are only available to me in compact so it is a moot point.



    Comfort guys have made really excellent points. So glad I asked on here from people who have done IM.



    Heres hoping the infinito is a good fit image I will take it for a long test ride before deciding on it.
  • Which ever one you buy, you will want a new one next week....i know i do

  • Isn't that what upgrading components is for? Anyway you always need another bike due to rule 12 (http://www.velominati.com/the-rules/)
