Hyro: Giant TCX SLR 2

This is a bicycle made for cyclocross racing – shorthand for “taking a drop-bar bike off-road.”

At the time of his release/purchase in 2014, disc brakes were just barely starting to make their presence felt on road bikes, but going cyclocross was the only practical option if you really wanted them. Hyro has since seen most of his kilometers on pavement, refitted as my idea of an all-conditions bicycle for commuting, randonneuring, or light touring.

  1. Hi Juan.

    After reading a lot (your articles included) I bought myself a 2017 Giant TCX SLR as a 5th bike.

    I use it for Audax rides on both gravel and tar. In my opinion the TCX is an awesome all rounder and should be the 1st bike that any serious beginner cyclist purchases.

    I wanted wider gravel tyres and was able to fit Fluid 29″ x 1.95″ Mountain Bike tyres without a problem on the standard SX-2 wheels.

    For road use I have purchased 700c x 32mm Armadillos that works well.

    I have also upgraded the FSA 36/46 crank to a Shimano 105 34/50 crank as this gives me a wider (climbing and sprinting) gearing range.

    Keep up the good work. I love reading your articles.

    1. Congrats on the purchase. The TCX has its flaws, but they’re pretty livable and none of them has been a deal breaker IMHO – at least not at the price point it sits in. The only real competitor I see it has is the Merida CX 500, but like the TCX it’s also a rather rare beast. I’m glad the blog was able to help you decide.

      Thanks for the fitment tip on the 29er knobbly tires.


  2. Hi I was wondering how you were able to mount the fenders only using the screws on the fork and chainstay… are they enough to hold the fenders in place?
