RossTopher Posted January 15 Share 38 minutes ago, Underachiever said: Can you please share your 105/grx mix details Ross? 105 shifters and brakes. Originally had a 105 RD but the "almost new" item I bought from the hub was basically scrap, so went for a GRX 810 RD along with the grx FD and 810 crank and a sram 11-36 cassette. Great gear ratios and no extra bits and pieces to make it work. Bought the grx stuff from merlin so didn't work out too expensive Underachiever 1 Link to comment Share on other sites More sharing options...

splat Posted January 15 Share 3 hours ago, Underachiever said: A frustration is when to find a good 2x (shimano) groupset if you do a custom build, even 105 is not available - unless I look in the wrong places.... If this is for a gravel bike, why not get GRX instead of Ultegra ? The clutch on the rear much is super useful for keeping that chain slap under control!

You might sukkel with Swartberg Grand Fondo, but on the other end of the scale (flat tar), you will wear down the 13 sprocket pretty quickly Edited January 16 by Underachiever eala 1 Link to comment Share on other sites More sharing options...

Agree, but I cannot find a full GRX gruppo, any ideas? 1st thing is to move from mech discs to hydraulics if I do a stepwise upgrade. Link to comment Share on other sites More sharing options...

Tip, the more bits you order, the cheaper shipping gets :). merlin doesnt stop Shimano to SA. i think sram is an issue though. Link to comment Share on other sites More sharing options...
Underachiever Posted January 15 Share 1 minute ago, Johan1983 said: So what will you recommend? For my MTB equivalent gear ratio you would need a 28x42 for the last 3km of Swartberg. Having said that, I've done Swartberg many, many times on a MTB, but never with a gravel bike, so not sure how the 1x gravel crowd manages their gears for the race. They most likely use a 50 cassette? Link to comment Share on other sites More sharing options...

Wont run out of gears? 1x gearing really depends on your preferred cadence, or your power. as you see from these comments, both @Jbr and @DMJ are running 10-50 cassettes, but one has a 38t and the other 46t. in my lack of knowledge, i feel a granny gear ratio of 25 gear inches to be about minimum for a gravel climber. 1:1 wont cut it DMJ and Akon 2 Link to comment Share on other sites More sharing options...
