Good bike - great for daily commute

sturdy, faster than you expect, comfortable

Rims/hubs; brake calipers

used for More than 1 year Bought this bike Aug 13 to have daily commute bike as quality of London roads meant I wanted aluminium commuter..
Overall quality for the amount paid is good; the new Sora speed shifters are step up from the old version.
Decided not to review until I done a good 1500km on it to really judge quality. So one year down the line, bike has survived reasonably well given the daily abuse it gets!
Issues that I noticed over the year
a) Bottom bracket needs tightening frequently - does have more flex than i like.
b) brake calipers are ok but no way near as good as even simple shimano tiagra's ( which only cost 19£ for the replacements- essential upgrade for central London commute)
c) the rear hubs are poor quality and not up to the job. First failed after 6 months and got replaced, three months in replacement wheel showing same issue. Similar reports can be found on web.
In summary, would still buy it but just be aware of the above.

used for 2 to 8 weeks After over a decade of using my trusty Raleigh M-Trax Team Titanium, on & off road, it was time to switch to a road bike (especially as I now live in Cambridge).
Staff at Lakeside were very helpful. suggested I took a quick test ride even though i already had reserved it & fitted bottle cage for me (saved me doing it!). After two weeks of riding it has been faultless. So fast & efficient. Will be doing my first sportive on it soon, London to Cambridge. I am sure it will give me many years of great riding! Did I mention how awesome it looks!?

My first Road bike, so know little! I've adjusted the handle bars up with an adjustable stem (bought from decathlon) once this was in place it has become a trusty steed..
In addition, the service from decathlon was very good. .

overall an amazingly cheap for the quantitt your recieving frame is adjile and light with full sora set excluding brake callipers but sora brake callipers in my opinion arent as smooth as these ..... recomended to any entry level rider weather for commuting or training

Still misleading with the product description

Very light, great Shimano gears, and great value

You don't get the advertised Hutchinson Tyres

Taking on first long ride tomorrow and really looking forward to putting it through its paces
