First Road Bike

At this price?

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!?

Looks good, great entry level bike

Nothing I wasn't expecting. ..

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 amazing

light 10.3kg with accesories in 57

if I`m nit picking the seat doesnt adjust its tilt

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

good all round bike for sportives

good sora spec and reasonable weight for the price

wrong spec advertised

overall good and well set up at the sheffield store. did a 50 miler first off with no hiccups its a good platform for upgrading. a similar bike elsewhere would be £600-700. Only letdown was you do not get the hutchison tyres nor the sora brakes as advertised here. However as a sportive it is a good competent all rounder and giddy to get going too. Buy one i have 13 bikes and im more than happy to have this in my artillery.

Response of the brand

Dear Sir,

I'm glad that you enjoy your bike.

I will send you a pair of hutchinson tyres. There was an early upgrade a few months ago from the b'twin tyres to prepare for the the 2014 tirban 500. I will arrange dispatch shortly. Thank you for letting us know.

Regarding the brakes, the specification on the website says b'Twin calipers. The 2014 triban 500 will be updated shortly with the sora brakes but the bike will retail for £449.99.
