Bike Fit Assistance

Hello all

Firstly let me apologise for yet another bike fit post.

I've been looking for a professional tri bike fit where I live but the closest person who confidently said they could fit a tri bike is a flight away interstate. And as much as you try to pick up things on the internet through other peoples experiences, its a bit of a steep learning curve.

I've had my tri bike for some time now and never really got it set up, the original fit came from the app - Best Bike Fit. Through a series of injuries (all from crashing the mountain bike) I've only really been able to race it once, avg 36km for the 60km. This was 2 years ago now and Im well behind what I was then in fitness terms!

One of the injuries I had was a torn rotor cuff in my right shoulder, which has caused the bike position to be a bit unbearable. Combined with my loss of flexibility, loss of time on the bike, etc I basically have to start from scratch.

Changes I have made since being able to train again:
- Base bar up (see photos for all the spaces). Its about 70mm.
- Change of base bar (oen that came with bike had no adjustment capacity at all)
- arm rests out wider (15mm each)
- cleats moved as far back on shoes as possible so they are more "mid-sole" (more to give it a try than anything else)
- seat lowered to compensate

This resulted in:

When riding with this position I can put down sufficient power but:
- not resting on bone structure so between shoulders and triceps get fatigued quickly
- constantly sliding forwards until I am perched on the edge of the saddle and feel like I need to shuffle backwards


Tried a different approach this morning and increased the tilt on the extensions, thinking it might allow me to lean into the arm rests a bit more and take pressure off my shoulders. Not being used to it at all I almost flipped over the bars when riding on it the first time... Still experiencing arm/back fatigue but not slipping forwards as much.

Now my partner is about to give birth and gives me a solid 2 weeks off work, so between sleeping, crying, changing shitty nappies, etc I'll be working on this (have some nice quiet straight roads 5 minutes from home).

What does the collective Slowtwitch think I can change to improve? I guess priority for me would be eliminating shoulder/arm fatigue. Any more photos/videos I can get readily (but they might be shaky if I recruit the son to do it). Also.. if you could tell me how to embed videos properly, that'd be rad!



Thanks in advance

I'm no fitter, but in the second pic you really look like you need to increase the reach. I think you need to stretch out a little, I think the reason you feel like you're going to fall over the bars is because you're elbows need to move forward.
