Trek District 8

Perfect riding position with seat adjusted back on my 54cm, great quality steel framed bike for road / paved leisure trail use.

Only has 8 gears so check if you have any super steep grades in your area as the gearing 'may' not be low or high enough for you. In my case it is perfect.

I would always buy Disc brakes on a bike - especially handy in the Wet vs traditional brakes after a dangerous non stop experience with traditional rim brakes on previous bike.
The Tektro Novela mechanical disc brakes have excellent stopping power, but a little fiddly to set up min gap & disc flex when re-installing wheels so there is no scrap noises. Rear was perfect, buy the front I matched the disc rounout to the hub & also straightened a run out spot in the disc.

Quality issues:
1) Derailleur hanger was on an angle - not picked up by bicycle shop that sold it.
Found masking tape had bee left behind from the frame painting process on the top machined hanger surface.
Once removed, perfect alignment to wheel as measured with a ParkTool aligner.

2) Tiawanese Pedals Wellgo M141 started cracking noises - loose screws between aluminium cage to plastichub, plus after 300km still rough to turn, swapped out for Wellgo M138 with one side sealed bearing & inner DU - Much better pedal, Why Trek bothered with the M141 pedals is beyond me.

3) Front tyre had a buldge at 90psi due to poor moulding manufacture of the Bontrager AW1 Hard-Case Lite, 700x32c, replaced under warranty.

4) Headset lower fork bearing race cracked 2 places, replaced under warranty - bad heat treatment / manufacture, was causing creak snap noise and was getting harder on turns. Still have the odd creak noise trying to narrow it the source (hope it is not the headset again).

Conclusion
Great road /smooth trail bike and really enjoy riding this one.
For a Trek entry level bike with mostly brand name parts I did expect better standard parts and assembly quality from a high volume bike manufacture.
